description

This bearing cup is made of hardened chrome bearing steel with super-finished raceway. It works together with cone and roller cage as a full tapered roller bearing set for heavy-duty transmission such as wheel end and gearbox under cyclic shock load. Raceway spalling, scratch, cup deformation and corrosion will lead to abnormal noise, overheat and excessive clearance, causing gear offset wear and axial movement, even transmission lock-up.

Part No.:7K-8876
Type: Tapered roller bearing cup
Material: Chrome bearing steel
Outer Diameter:90 mm
Process: Forging, quenching and superfinishing
Matching System: Transmission, wheel end reduction assembly

Application Scenarios

Fits multiple Caterpillar wheel loaders and small bulldozers, for overhaul of bearing positions in transmission, wheel reducer and steering assembly.

FAQ 

Q：Can slightly rusted cup be reused after polishing?
A：Not recommended. Polishing changes outer dimension, loose fit causes cup creep and overheating.

Q：Can I replace only the cup while cone and rollers are intact?
A：Not recommended. Raceways are wear-matched. New cup with old cone causes poor contact and early spalling.

Q：What risk exists if striking cup end during pressing?
A：Impact creates hidden crack and surface stress, which leads to raceway spalling after operation.

Q：Does hot bearing mean the cup is damaged?
A：Not necessarily. Check preload, lubrication and contamination first before judging cup failure.
