Product Description

Faster, easier mounting and dismounting

On some paper machines, bearing mounting and dismounting can be facilitated by the use of SKF sleeves. Adapter sleeves enable bearings to be mounted on smooth shafts as well as on stepped shafts. Mounting is made easier and no additional location on the shaft is required. Expensive machining of the shaft can also be avoided. For mounting bearings on stepped shafts, it is possible to use withdrawal sleeves as well. All SKF high quality sleeves contribute to optimal bearing performance and long service life.

Tapered seat direct on journal is however recommended when the bearings run at high speed and/or high running accuracy is required.

1) Adapter sleeves are the most commonly used components for locating bearings with a tapered bore onto a cylindrical seating as they can be used on smooth or stepped shafts.
2) They are easy to mount and require no additional location on the shaft.
3) When adapter sleeves are used on smooth shafts, the bearing can be located at any position on the shaft.
4) When used on stepped shafts, together with an abutment ring, bearings can be accurately positioned axially and bearing dismounting is also facilitated.
