Drawn cup needle roller bearing BK0912 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
