Q: What is a bearing cup and what does it do?
A: A bearing cup is the outer race of a tapered roller bearing assembly. It works with a corresponding bearing cone to allow wheel and axle rotation under load. The hardened raceway surface distributes force evenly across the roller elements.
Q: Why are the raceway surfaces ground and polished?
A: Ground and polished raceways reduce friction and wear in the bearing assembly. This precision finish ensures smooth wheel rotation and extends the service life of the bearing under the constant load cycles of electric lift truck operation.
