Cylindrical Roller Bearing
Product Specification

Cylindrical roller bearings offer excellent resistance to instantaneous overloads and shocks.

They simplify assembly thanks to their detachable elements and allow, for certain types, axial displacement or low axial load, for other types.

Cages

The standard cage for these bearings is the polyamide cage which allows bearing operating temperatures of 120°C or 248°F (150° or 302°F peak). The standard cage for series 4 is in pressed steel. The machined brass cage is available on option. Large-dimension bearings are equipped with a machined brass cage. For special applications in which the synthetic material cage is unacceptable, a metal cage can be provided on request.

Capabilities

Loads and speeds

Cylindrical roller bearings are designed to

  • Withstand radial loads
  • Withstand moderate axial loads if the position of the shoulders on the rings allows them accept high speeds of rotation

Misalignment

Cylindrical roller bearings accept misalignment of about 0.06° thanks to the correction on the roller surface profile
