Single row needle roller bearings with machined collar without retaining ring and inner ring.

Single row needle roller bearings without inner ring consist of an outer ring assembly with needle rollers and cage. In applications with hardened and ground raceways on the shaft surface, these bearings are an excellent choice for compact bearing configurations. The bearings with a non-retaining outer ring are separable, i.e. the outer ring and the needle roller and cage assembly can be mounted separately and individually.

  • High radial load carrying capacity
  • High rigidity
  • Small cross-section
  • Can withstand bi-directional axial displacement
