2. What Is a SCANIA Universal Joint?
เอ SCANIA Universal Joint — commonly called a U-joint or cardan joint — is a rigid mechanical coupling that connects two rotating shafts whose axes are not perfectly aligned. In heavy-duty trucks and coaches built on SCANIA platforms, the universal joint sits at critical transition points of the driveline: between the gearbox output and the propeller shaft, between shaft segments, and at the differential input. Without a reliable SCANIA universal joint, no amount of engine power can be transferred cleanly to the driven axle. Any wear, play, or fracture in the joint produces vibration, noise, and ultimately driveline failure — which is why choosing a replacement that matches OEM geometry and material grades is absolutely non-negotiable for fleet operators and independent workshops alike.
Our EP-HS Series covers the complete range of SCANIA universal joint sizes used across SCANIA P, G, R, and S series trucks as well as Interlink and OmniExpress coach platforms. Each part number in the series has been dimensionally verified against original SCANIA specifications and stress-tested to confirm load ratings suitable for gross vehicle weights up to 40 tonnes on paved roads and the demanding unpaved corridors common throughout Colombia, Brazil, and other high-growth commercial-transport markets in Latin America.
3. Five Key Product Advantages
Why fleet engineers, spare-parts distributors, and workshop technicians across the Americas specify our EP-HS Series SCANIA Universal Joint.
OEM-Matched Geometry
Every journal cross diameter, cup outer diameter, and overall length in our EP-HS SCANIA Universal joint range has been verified directly against original SCANIA engineering drawings. From the compact HS239S (φ38×148 mm) to the heavy-duty HS292T (φ57×164 mm), dimensional tolerances are held to ±0.02 mm so your driveshaft balances correctly out of the box, without shimming or secondary machining.
High-Grade Alloy Steel Construction
Journal crosses and bearing cups are machined from 20CrMnTi or 20CrNiMo case-hardening steel, vacuum degassed for purity. After precision machining, parts undergo carburizing and quenching to achieve a surface hardness of 58–62 HRC with a tough, fatigue-resistant core. This combination resists both the surface wear of boundary-lubrication starts and the subsurface fatigue that destroys lower-grade parts on high-torque SCANIA applications such as tipper trucks and off-road logistics vehicles.
Extended Lubrication Intervals
Bearing needles run inside precision-ground cups pre-packed with high-pressure, high-temperature NLGI 2 lithium-complex grease and sealed with lip-type seals rated to 150°C continuous service. For fleets operating in the high-altitude Andean corridors of Colombia or the humid coastal lowlands, a grease nipple variant is available so technicians can re-lubricate on schedule without disassembly, dramatically reducing unplanned downtime per vehicle.
Dynamic Balance Certification
Each EP-HS Series SCANIA universal joint assembly is dynamically balanced to G6.3 standard or better before leaving the production line, reducing residual imbalance to below 25 g·mm at rated RPM. This is particularly important for long propeller shafts on SCANIA intercity coaches and heavy haulage tractors where even minor imbalance translates into perceptible cabin vibration and accelerated driveshaft centre-bearing wear over transcontinental distances.
Full Cross-Reference Coverage
Our EP-HS Series SCANIA Universal joint is catalogued against GKN, SPICER, GMB, and original SCANIA part numbers simultaneously, making procurement straightforward for spare-parts managers who maintain mixed-brand inventories. Whether your purchasing system references GKN HS268S, SCANIA OEM 294383, or the original number 365913, a single lookup maps to the correct EP-HS part — eliminating costly errors and reducing the warehouse SKU count for common SCANIA universal joint applications.
4. Universal Joint Working Principle
Understanding the universal joint working principle is important for anyone specifying or servicing driveline components on SCANIA heavy commercial vehicles. At its core, the U-joint consists of a cross-shaped journal (the spider) whose four trunnions each fit into needle-roller-bearing cups. Two of these cups are locked into one yoke, and the other two into a second yoke rotated 90° relative to the first. When one shaft rotates, the spider transmits torque to the other shaft even if the two shafts form an angle — the joint flexes about both pairs of trunnions simultaneously.
In a SCANIA truck driveline, there is an important characteristic to understand: a single Hooke-type universal joint delivers non-uniform angular velocity output whenever the joint angle exceeds a few degrees. The driven shaft accelerates and decelerates twice per revolution of the input shaft. This velocity fluctuation creates vibration, second-order harmonics, and additional stress on driveshaft components. SCANIA engineering addresses this by pairing joints in phase — the propeller shaft arrangement has the front and rear yokes in the same plane (phased), so the two joints cancel each other’s non-uniformity and the axle shaft receives a nearly constant velocity input. This is why replacement SCANIA universal joints must be installed with the correct phasing; reversing yoke orientation doubles rather than cancels the velocity error.
The bearing cups in our EP-HS Series use full-complement needle rollers machined to DIN 5402 tolerances. Under torque, the needles generate an elastohydrodynamic film that separates the rolling elements from the hardened cup bore, distributing contact stress evenly and extending service life. When the joint articulates to larger angles — as happens when a SCANIA vehicle negotiates tight construction-site turns or deeply rutted rural roads in Colombia’s Llanos region — the needles oscillate back and forth rather than rotating continuously. This oscillating-contact regime demands a grease that retains its film strength under partial EHD conditions, which is exactly what our pre-filled NLGI 2 lithium-complex formulation is optimised for.
5. Materials & Manufacturing Standards
The durability of any SCANIA universal joint replacement hinges almost entirely on material quality and heat treatment precision. Our EP-HS Series uses a carefully specified material stack for each functional component of the assembly.
The journal cross body is forged from 20CrMnTi alloy steel conforming to GB/T 3077 and its closest international equivalents (EN 1.7218 / SAE 8620). Forging rather than machining from bar stock aligns the grain flow of the steel with the direction of service load, increasing fatigue strength by up to 30 percent compared with machined blanks at equivalent hardness. After forging, each cross undergoes precision CNC turning and cylindrical grinding to achieve trunnion diameters accurate to IT6 tolerance and a surface roughness Ra ≤ 0.4 μm, which is the finish required for correct needle bearing contact.
Bearing cups are produced from 20Cr or 20CrMo steel and deep-drawn to near-net shape before precision grinding of the bore. The bore surface hardness, achieved through case-hardening to a depth of 0.8–1.2 mm, is 58–62 HRC — hard enough to resist needle indentation but not so hard as to be brittle under shock loads from road impacts or clutch engagement on SCANIA trucks with manual gearboxes. Needle rollers themselves meet DIN 5402 grade G3, with diameter tolerance ≤ 2 μm and roundness ≤ 1 μm, ensuring load is shared equally among all rollers in the cup.
Seals are moulded from NBR (acrylonitrile-butadiene rubber) or FKM (fluoro-elastomer) depending on the application. FKM seals are standard on versions intended for higher operating temperatures or where contact with ATF fluid is a concern. Snap rings and circlips are hardened carbon-spring steel, zinc-chromate plated for corrosion resistance in the salt-laden coastal air common in Colombian port cities such as Barranquilla and Cartagena. All surface-treated parts comply with EU RoHS 2011/65/EU by using trivalent chromate coatings — hexavalent chrome is not used at any stage of production.
6. Regulatory & Compliance Framework
Spare parts for heavy commercial vehicles — including the universal joint in car and truck applications — are subject to an increasing body of regulation across the markets where SCANIA vehicles operate.
Colombia (Registro de Libre Importación / NTC Standards): In Colombia, automotive spare parts do not require a specific approval certificate in the way that OEM-equivalent parts are handled in some markets, but importers must comply with DIAN (Dirección de Impuestos y Aduanas Nacionales) tariff classification under heading 8708.99 (parts and accessories of motor vehicles) and must ensure parts meet the technical requirements referenced in ICONTEC’s NTC standards applicable to road vehicle components. Vehicles in commercial operation must pass mandatory revision técnica vehicular (technical inspection) where driveline play and noise are evaluated; installing non-conforming universal joint parts can result in inspection failure and vehicle immobilisation.
European Union (ECE Regulations & REACH): SCANIA trucks destined for European markets or used by multinational operators must comply with UN ECE Regulation 10 (electromagnetic compatibility) and ECE R13 (braking, indirectly affecting driveline integrity). More directly relevant, REACH Regulation (EC) No 1907/2006 restricts substances of very high concern (SVHCs) in parts and assemblies sold in the EU or supplied to EU-based manufacturers. Our EP-HS SCANIA universal joint set uses no restricted phthalates, lead compounds, or hexavalent chromium, ensuring full REACH compliance for re-export or use in European assembly.
Brazil (INMETRO / CONTRAN): Brazil’s INMETRO certification scheme for automotive parts, implemented under CONTRAN Resolution 432, covers safety-critical components. Universal joints are classified as functional safety components for heavy vehicles. Importers supplying fleet operators in Brazil must verify that parts are manufactured under a quality management system meeting ISO 9001:2015 at minimum, and must retain technical files demonstrating dimensional conformance to OEM specifications for audit by DENATRAN (now SENATRAN) or state traffic authorities.
Mexico (NOM Standards): Mexico’s NOM-086-SCT2 and related SCT2 technical standards govern roadworthiness of heavy commercial vehicles. Driveshaft components including universal joints must not exhibit play exceeding OEM-specified limits during periodic inspection. Using non-OEM-dimensioned universal joint parts that introduce additional clearance can cause vehicles to fail inspection under the federal transport authority (SCT).
ISO Quality System: All EP-HS Series parts are produced under ISO 9001:2015 certified quality management, with full traceability from raw material heat number to finished part batch number, supporting any regulatory audit requirement across Latin American or global markets.
7. Universal Joint Application Scenarios
The EP-HS Series SCANIA universal joint set covers a broad range of commercial vehicle applications where reliable power transmission is critical to operational continuity.
Long-Haul Freight Tractors
SCANIA R-series and G-series tractors pulling 48-tonne combinations across the Panamericana and Troncal del Magdalena in Colombia place extreme cyclic torque through the driveshaft universal joints. The HS292S and HS292T joints (φ57×164 mm) are the standard fitment on these applications, handling rated torques above 5,000 Nm while articulating through the 3–5° angles typical of a two-piece propeller shaft. Replacement intervals in this service are typically 400,000–600,000 km depending on grease re-lubrication discipline and road surface quality.
Urban Transit & Intercity Coaches
SCANIA OmniExpress and Interlink coach chassis used on Colombian inter-departmental routes between Bogotá, Medellín, and Cali require universal joint parts with lower journal diameters (HS239S, HS244) to suit slimmer propeller shaft designs that fit within the lower floor height constraints of bus bodywork. These applications see higher articulation angles than truck applications because engine and rear-axle layout forces a larger driveshaft angle. The slip-yoke (FIG J) configuration compensates for chassis flexion between laden and unladen states without introducing binding.
Construction & Mining Tippers
Tipper trucks operating in Colombian open-cast coal and nickel mines (Cesar, Córdoba, and Chocó departments) subject universal joint truck drivelines to severe shock loading as heavily loaded bodies raise and lower the vehicle’s centre of gravity, changing propeller shaft angles dynamically. The HS381 and HS280 mid-range joints are commonly fitted to 8×4 rigid tippers, offering a balance between torque capacity and angular flexibility while remaining compact enough for twin-propeller-shaft arrangements with centre-bearing support.
Steering Column Universal Joint Applications
Beyond the main driveline, SCANIA vehicles also use smaller steering universal joint components in the steering column intermediate shaft. These steering column universal joint assemblies must transmit precise steering feel from the wheel to the rack while accommodating the angular offset created by the cab tilt mechanism. Our EP-HS steering series uses smaller journal crosses (φ38–φ39 mm range) with minimum radial clearance to preserve steering response and prevent the “dead band” feel that worn steering joints create on SCANIA trucks after high mileage.
Agricultural Machinery & Special Vehicles
SCANIA industrial engines are also used in agricultural and municipal vehicles where a universal impact joint or heavy-duty cardan joint transfers power from the engine to processing equipment via PTO shafts. Larger-diameter EP-HS joints (HS316, HS380 series) with higher torque ratings are suitable for these applications. The flanged (FIG A) configuration allows direct bolted assembly to standard SAE companion flanges, making installation straightforward even in custom-built vehicle applications common in the Colombian sugarcane and cut-flower agricultural sectors.

คำถามที่พบบ่อย
Q1. What does a SCANIA Universal Joint actually do on a truck and why does it fail? ▼
A SCANIA Universal Joint transmits rotational power from the gearbox or transfer case through the propeller shaft to the drive axle while accommodating the angular misalignment between those components. Failure most commonly results from inadequate re-lubrication (allowing the needle bearings to run dry), excessive operating angle caused by incorrect chassis levelling or overloading, or shock-loading from clutch drops and hard starts. Regular lubrication at the intervals specified in the SCANIA vehicle maintenance manual and prompt replacement when vibration or knocking is heard can prevent costly driveshaft and gearbox damage downstream.
Q2. How do I find the correct replacement SCANIA Universal Joint part number for my truck in Colombia? ▼
The easiest method is to locate the original SCANIA part number stamped on the existing joint’s bearing cup or noted in the vehicle’s service record. Cross-reference that number against our EP-HS Series catalogue, which lists GKN, SCANIA OEM, GMB, SPICER, and original numbers in parallel columns. If the part number is not visible, measure the trunnion outer diameter and the overall length between cup faces and match those to the SIZE column in our reference table. Our technical sales team, reachable through our website, can assist with cross-referencing for Colombian-registered SCANIA fleets.
Q3. What is the difference between FIG A and FIG J SCANIA universal joint configurations? ▼
FIG A refers to a flange-yoke design where the yoke has a flat mounting face with bolt holes for direct attachment to a companion flange on the gearbox or differential. FIG J refers to a slip-yoke design where one yoke has a splined internal bore that slides onto a matching splined shaft section, allowing the driveshaft to change length as the suspension moves or the chassis flexes. On SCANIA trucks the front end of the propeller shaft typically uses a slip-yoke (J) to accommodate chassis flex during off-road driving, while both ends may be flanged (A) on rigid shorter shafts.
Q4. Which universal joint types are used in SCANIA truck steering column systems and can they be replaced independently? ▼
SCANIA steering systems use compact needle-bearing universal joints in the intermediate shaft between the steering column and steering gear. These steering column universal joint assemblies are a different product from the driveline propeller-shaft joints and use much smaller journal diameters, typically in the φ16–φ25 mm range. They can generally be replaced as standalone units without removing the entire steering column. Excessive free play in the steering — experienced as a “loose” wheel on-centre feel — is often the first symptom of a worn universal steering joint and should be investigated before the condition worsens.
Q5. What is the main function of a universal joint in a SCANIA driveline compared to a CV joint? ▼
Both universal joints and CV (constant-velocity) joints transmit torque through an angle, but they do so in fundamentally different ways. A standard Hooke-type universal joint, such as those in the EP-HS SCANIA series, delivers non-uniform output velocity at large angles — the driven shaft slightly speeds and slows twice per revolution. CV joints maintain exactly constant output speed at any angle, which is why they are preferred for front-wheel-drive passenger car axle shafts where the large angular range would otherwise cause severe vibration. In SCANIA heavy truck drivelines, the small propeller-shaft angles involved (typically 3–7°) mean the non-uniformity of paired Hooke joints is acceptably low, and the higher torque capacity and simpler serviceability of the universal joint makes it the preferred choice over CV joints.
Q6. What are the signs that a universal joint on a SCANIA truck needs immediate replacement and is unsafe to drive? ▼
The clearest warning signs are: a clunking or knocking sound from under the vehicle during acceleration or deceleration gear changes; vibration felt through the floor or seats that increases with vehicle speed; visible rust streaks or grease deposits radiating from the joint area (indicating failed seals and dry running); and any perceptible rotational play when rocking the propeller shaft by hand with the drivetrain stationary. Any of these symptoms warrants immediate inspection. A universal joint that is close to total failure can separate at highway speed, which causes the propeller shaft to drop and dig into the road surface — a potentially catastrophic safety event on Colombian highways.
Q7. Does the EP-HS SCANIA Universal Joint set come with all hardware needed for installation by a workshop in Colombia? ▼
Yes. Each EP-HS SCANIA Universal Joint set is supplied as a complete kit containing the journal cross assembly with pre-fitted needle bearing cups, new snap rings or circlips matched to the specific journal diameter, and a grease nipple where applicable to the variant. The sealed-for-life variants include a measured quantity of pre-packed grease sufficient for the rated service interval. No additional hardware is required for a standard workshop replacement. We recommend using a proper u-joint press tool rather than a vice or hammer during installation to avoid damaging the bearing cup bores or distorting the snap ring grooves — a common workshop error that shortens joint life significantly.
