Product description:

  • Tapered roller bearings have an inner and outer ring with tapered raceways between which tapered roller bodies are arranged
  • Due to their design, tapered roller bearings are ideally suited for taking combined axial and radial loads
  • The axial load carrying capacity of bearings is largely paid for by the contact angle
  • The larger this angle is, the higher the axial load carrying capacity is
  • Tapered roller bearings can generally be separated into the cone, consisting of the inner ring with cage and roller bodies and the cup (outer ring)
