Raceways on shafts and in housings

In order to save space, the rolling elements of cylindrical, needle or tapered roller bearings can run directly on raceways on the shaft and/or in the housing. To fully exploit the load carrying capacity, the raceways should comply with certain requirements, including:
  • suitable material properties such as cleanliness, hardness and heat treatment
  • suitable roughness and surface texture
  • adequate tolerances for profile, roundness and total run-out
