NSK Cage & Needle Roller Assemblies

High Load Capacity Cage & Roller Assemblies | Compact Bearings for Planetary Gears & Gearboxes
Cage & roller assemblies are easy-to-handle bearings that offer high load capacity despite their small size. A unique cage structure guides the needle rollers and allows for effective lubrication even at high speeds.
Cage & roller assembles feature controlled contour crowning to reduce stress concentrations on the roller end from moderate misalignment/shaft bending, thereby extending bearing life.

Features

  Easy-to-handle, with a unique cage structure that keeps the rollers in place.
• Easy-to-lubricate
  The outside surface of the cage forms the guide surface, providing good lubrication conditions.

Applications
