Description
Maximize rotational precision and withstand severe combined loads across your commercial fleet with the genuine SKF Heavy Duty Commercial Vehicle Angular Contact Ball Bearing. Engineered specifically for heavy-duty commercial truck gearboxes, final drive pinions, power take-off (PTO) units, and engine superchargers, this OE-grade bearing supports heavy combined radial and axial loads simultaneously. Pitted raceways, spalled steel balls, improper preload clearance, or lubricant thermal breakdown cause severe transmission shaft misalignment, loud gear whining, excessive axial play, and catastrophic gearbox lockups. This original SKF angular contact ball bearing solves those mechanical driveline failures directly. It features premium high-purity 100Cr6 bearing steel, precise contact angle geometry, reinforced cages, and super-finished ball raceways to deliver uniform load distribution, ultra-low friction torque, and uncompromised fleet reliability in demanding transport operations.
Technical Parameters
| Category | Specifications & Technical Details |
| Precision Contact Angle Geometry | We design the inner and outer ring raceways with precise 25° or 40° contact angles. They evenly transfer radial load and one-direction high axial thrust along the inclined contact line. As a result, this greatly improves axial load capacity. |
| Universally Matched & Tandem/DB/DF Pairing | We support flexible pairing in face-to-face (DF), back-to-back (DB), or tandem arrangements. This perfectly solves the bidirectional high axial thrust challenge on heavy truck gearbox and differential input shafts. |
| High-Purity Vacuum-Degassed 100Cr6 Steel | We manufacture the rings and steel balls from deep-hardened high-purity bearing steel. It delivers extremely strong resistance to rolling contact fatigue spalling. Moreover, it easily withstands long-term high speed and high-pressure tangential stress. |
| Reinforced Brass & Polymer Roller Cage | We equip precision-machined brass or reinforced polymer cages. They keep the steel balls running smoothly under high speed, alternating impact, and high oil temperature. Notably, they completely prevent seizure. |
| OEM Super-Finished Raceway Finish | We micron-level super-finish the inner and outer ring raceways. This greatly reduces rolling friction resistance and heat buildup. Consequently, the bearing maintains extremely low noise and high efficiency during high-speed operation. |
Applicable Car Brands & Models
Common warning symptoms include:
High-Pitched Gearbox Whining or Grinding: A persistent mechanical noise coming from the transmission or differential that changes volume or frequency under throttle acceleration/deceleration.
Excessive Transmission Shaft End-Play: Radial or axial runout detected on the input shaft or pinion shaft during driveline maintenance.
Gear Disengagement or Jumping: Gears popping out of mesh under heavy load due to shaft misalignment caused by worn bearing raceways.
High Operating Oil Temperature: Transmission fluid temperatures spike significantly due to increased friction and thermal breakdown inside the bearing.
Single angular contact ball bearings can only accept axial loads in one direction. Installing them in matched pairs (back-to-back DB or face-to-face DF) enables the bearing unit to handle heavy dual-direction axial thrust loads while maintaining precise shaft preload and rotational accuracy.
No. Fleet technicians strongly advise against replacing only one bearing in a paired set. SKF matched bearings are manufactured with micro-inch paired tolerances; mixing new and worn bearings causes uneven load distribution, premature spalling, and rapid bearing failure.
Our 1-year warranty covers all raceway spalling, ball fatigue fracture, cage structural damage, manufacturing dimensional flaws, and non-artificial mechanical failures under normal operating and lubrication conditions. If a bearing fails within 12 months, we provide prompt replacement or warranty processing upon inspection.
