Technical information on Needle roller bearings, aligning needle roller bearings

The bearings:

  • can support high to very high radial forces
  • are used when the load carrying capacity or accuracy of drawn cup needle roller bearings with open ends is no longer sufficient and the high load capacity of cylindrical roller bearings is not yet required
  • can only support radial loads and, as a result, are highly suitable for use as non-locating bearings (they permit axial displacement of the shaft relative to the housing in the bearing)
  • permit high speeds in spite of line contact
  • compensate misalignments between the shaft and housing (aligning needle roller bearings)
  • require only a very small radial design envelope, particularly if the bearing arrangement is designed without an inner ring
  • are available in numerous sizes and designs
  • result in particularly compact, cost-effective and economical bearing arrangements

Technical information on Needle roller and cage assemblies

 

Radial needle roller and cage assemblies:

  • are suitable for applications with a very small radial design envelope, where the raceways on the shaft and in the housing are designed as rolling bearing raceways (direct bearing arrangement)
  • can support high radial loads
  • allow high speeds
  • combine the load carrying capacity advantages of full complement needle roller bearing arrangements with the speed advantages of a cage bearing
  • have a high running accuracy
  • result in rigid bearing arrangements
  • are easy to mount
    • permit technically straightforward, economical and cost-effective designs
