Needle Roller Bearings



SKF needle roller bearings are bearings with cylindrical rollers that are small in diameter relative to their length The modified roller/ raceway profile prevents stress peaks to extend bearing service life SKF supplies needle roller bearings in many different designs, series and in a wide range of sizes, which make them appropriate for a wide variety of operating conditions and applications Bearing features

  • Low cross section in applications where less space is available, needle roller bearings offer a very compact solution, and drawn cup needle roller bearings enable downsizing
  • High load carrying capacity Owing to their large number of rollers, needle roller bearings have a high load carrying capacity
  • High stiffness Because of their large number of small-diameter rollers, needle roller bearings have high stiffness More information General bearing knowledge 17 Bearing selection process 59 Lubrication 109 Bearing interfaces 139 Selecting internal clearance 182 Sealing, mounting and dismounting 193
  • Separable design the possibility of assembling inner and outer rings separately permits interference it’s 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 Alignment needle roller bearings are self-aligning up to 3° of static misalignment
  • Locating bearing arrangement Combined needle roller bearings accommodate combined radial and axial loads in one or both directions
