Designs and variants

SKF supplies alignment needle roller bearings with (fig. 1) or without (fig. 2) an inner ring.
Bearings with an inner ring
  • should be used in applications where the shaft cannot be hardened and ground
  • have limited permissible axial displacement (→ product table) of the shaft relative to the housing, which can be extended, if needed, by using a wide inner ring (→ Needle roller bearing inner rings)
Bearings without an inner ring
  • are an excellent choice for compact bearing arrangements, if the shaft can be hardened and ground
Cages

SKF alignment needle roller bearings are fitted with one of the cages shown in table 1.

For additional information about the suitability of cages, refer to Cages and Cage materials.
