SKF needle roller bearings SKF NAO 50X68X20

Single row needle roller bearings have a smaller diameter relative to their length. Due to the large number of rollers, the bearing has a large load carrying capacity. The outer ring flange bearing is separable, i.e. the outer ring and needle roller and cage assemblies can be installed separately. The inner ring contains a lubrication hole for easy relubrication.

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