Adapter Sleeves

Adapter sleeves are typically used to locate bearings with a tapered bore on cylindrical shafts. Installation is very straightforward because the bearing is simply
pressed onto the adapter sleeve until the required reduction in radial internal clearance is achieved. Because adapter sleeves require no additional means of retention on the shaft, the bearings can be positioned at any point on shafts that have a consistent diameter.
If adapter sleeves are used with a support ring on stepped shafts, the bearings can be axially located with high accuracy.

Adapter sleeves are suitable for locating bearings with a tapered bore on
cylindrical shafts, whereby:

• Adapter sleeves require no additional means of retention on the shaft.

Locknuts and shaft nuts are suitable for locating bearings on cylindrical and tapered shafts as well as on adapter sleeves, and for mounting and dismounting bearings on withdrawal sleeves, whereby:

• Locknuts can be easily tightened using a striking wrench or a spanner wrench.
• Shaft nuts do not require any slots on the outside of the shaft, which increases the strength of the shaft and makes it easier to manufacture.
  

Tab washers and retaining plates are suitable for securing locknuts, whereby:

• Tab washers are used for smaller locknuts (SNW).
• Retaining plates are utilized for larger locknuts (SNP).
