needle roller bearings

Needle Roller Bearings


  • Low cross section
  • High load carrying capacity
  • High stiffness
  • The possibility of assembling inner and outer rings separately permits interference fits for shaft and housing and also enables easy maintenance inspections
  • Accommodate axial displacement Except for bearings with flanges on both the inner and outer rings, needle roller bearings with machined rings can accommodate axial displacement
  • Accommodate static misalignment
  • Locating bearing arrangement Combined needle roller bearings accommodate combined radial and axial loads in one or both directions
