SKF needle roller bearings SKF NK 37/20

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. Integral flanges on both sides of the outer ring for axial guiding bearings, lubrication grooves with one or more lubrication holes for easy relubrication.

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