description

Tapered roller bearing cup is the outer race component of tapered roller bearing, matched with inner race, rollers and cage. It carries heavy radial load and one-way thrust load, commonly used in final drive and transmission. Race spalling, scoring, hardness loss and excessive fit clearance will cause abnormal noise, overheating and axial movement, and even roller seizure and gear damage.

FAQ 

Q：Can bearing cup with light rust stains be installed?
A：Not recommended. Rust spots damage race finish and will induce pitting by grinding rollers.

Q：Can this cup be matched with other cone parts?
A：No. It must be paired with 126-0587 cone. Mismatched taper causes incorrect preload.

Q：What trouble will excessive preload bring?
A：High friction and continuous overheating, grease carbonization and premature seizure.

Q：Why does the bearing feel stiff after assembly?
A：Usually caused by over-preload, misalignment or housing burrs, disassemble and inspect again.
