CUSCINETTO RULLINI RNA 6908 ZW – Cuscinetti a rullini

Description

Double row needle roller bearings without an inner ring consist of an outer ring with two needle roller and cage assemblies. They are an excellent choice for compact bearing arrangements in applications where hardened and ground raceways can be provided on the shaft. The outer ring includes flanges to guide the roller and cage assemblies and has features to facilitate relubrication. The roller and cage assemblies and the outer ring form a non-separable unit.

  • High radial load carrying capacity
  • High stiffness
  • Low cross-sectional height
  • Accommodate axial displacement in both directions
  • Enable a larger shaft diameter and a more rigid bearing arrangement
