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 minor race scratches continue to be used?
A：Not recommended. Scratches accelerate roller wear, cause overheating and noise and lead to premature failure.

Q：Can I replace only the cup and reuse the old cone and rollers?
A：Not recommended. Tapered roller bearings are matched sets; mismatched contact causes early failure.

Q：What happens if you strike the raceway during installation?
A：Indentation and stress concentration appear on raceway, resulting in pitting, spalling and shortened service life.

Q：Will new bearing cup work if the housing bore is worn?
A：Poor effect. Loose bore causes cup creep, overheating and rapid damage, repair housing bore first.
