Product description

Single row needle roller bearings incorporate cylindrical rollers that are small in diameter relative to their length. Owing to their large number of rollers, the bearings have a high load carrying capacity. The outer ring includes two integral flanges to guide the bearing axially and an annular groove with one or more lubrication holes to facilitate relubrication.

  • High radial load carrying capacity
  • High stiffness
  • Low cross-sectional height
  • Accommodate axial displacement in both directions
  • Separable design
