Bearings on sleeves

Spherical roller bearings with a tapered bore can be mounted on smooth or stepped shafts using
  • an adapter sleeve (fig 1)
  • a withdrawal sleeve (fig 2).
The sleeves facilitate bearing mounting and dismounting and often simplify bearing arrangement design.
When sealed bearings are to be mounted on an adapter sleeve it is necessary to protect the sealing lips from being damaged. This can be done by
  • using an E-design adapter sleeve (see section Adapter sleeves)
  • inserting an intermediate ring between the bearing and the locking washer (fig 3).
