SKF needle roller bearings SKF RNAO 12X22X12 TN

Single-row needle roller bearings without inner rings consist of an outer ring assembly with needle rollers and cages. In applications with hardened and ground raceways on the shaft surface, this bearing is an excellent choice for compact bearing arrangements. The outer ring flange bearing is separable, i.e. the outer ring and needle roller and cage assemblies can be installed separately.

  • High radial load-bearing capacity
  • High rigidity
  • Small cross-section
  • It can withstand bidirectional axial displacement
