HK 4520
Drawn cup needle roller bearing with open ends
Drawn cup needle roller bearings are typically used in applications where the housing bore cannot be used as a raceway for a needle roller and cage assembly, but where a very compact and economical bearing arrangement is required. Owing to their large number of rollers, the bearings have a high load carrying capacity and stiffness.
High radial load carrying capacity
High stiffness
Very low cross-sectional height
