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
