Part name: Roller Bearing Cage for Railway Application
Description:
In roller bearings, the cage keeps the rolling elements separated and equidistant during operation of the bearing. The surface of the roller housings must be characterized by very low roughness, so as to allow the sliding between roller and cage without dissipating energy in rolling friction. Cages are produced with glass fiber added granules, with high elasticity and limited specific weight. Diameter ranges from about 250 mm up to 400 mm.
General characteristics:
  • PA66 and PA46 polymers with glass fiber added
  • High flexibility and low weight
  • Extremely small dimensional tolerances
