BK 3520
Drawn cup needle roller bearing with a closed end
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 the large number of rollers, the bearings have a high load carrying capacity and stiffness. The closed end makes them suitable for bearing arrangements where they are situated at the end of a shaft.
High radial load carrying capacity
Accommodate small axial guidance forces
High stiffness
Very low cross-sectional height
