Radial style bearings for high speeds and heavy loads

IKO manufactures a wide range of radial needle roller bearings to meet the needs of different applications and machine profiles. These include shell type bearings, needle roller cages for both general use and within engine connecting rods, and machined type needle roller bearings.

Machined type needle roller bearings feature low sectional height and large load ratings. A highly rigid outer ring makes these bearings ideal for light alloy housings as well. Three styles are available: Caged, Guided and Capilube.

  • Metric and inch versions available.
  • Caged and full complement design options.
  • Suitable for a wide range of conditions including heavy loads requiring either high-speed or low-speed rotation.
  • Design choices include bearings with or without inner rings. Ringless style uses a shaft as the raceway for a streamlined, compact footprint.
