Adapter sleeves

  • Tightening sleeves are the most common component used to locate bearings with tapered bores into cylindrical housings, as they can be used on plain or stepped shafts.
  • They are easy to install and do not require additional locations on the shaft. When used on a light shaft, the bearing (Adapter sleeves )can be located anywhere on the shaft. When used with L-spacers on stepped shafts, they allow for accurate axial positioning of the bearing and easy mounting and dismounting of the bearing.

Fastening Sleeve - Tool and Accessory Selector

The SKF Tool and Accessory Selector is used to select the correct tools and accessories for mounting SKF spherical roller bearings, (Adapter sleeves) CARB circular roller bearings and SKF self-aligning ball bearings on sleeves and tapered shafts.

Features and Benefits

  • Fastening sleeves (Adapter sleeves) are the most common component for locating bearings with tapered bores in cylindrical housings, as they can be used for light or stepped shafts. They are slit and are equipped with a KM locknut and an MB lock washer.
  • Easy to mount
  • with locking nut
  • With locking device


Loads are defined by their direction. Loads perpendicular to the shaft are called radial loads and loads parallel to the shaft are called axial (thrust) loads.

DGBB can carry axial loads in both directions, whereas angular contact ball bearings can only carry axial loads in one direction.

  • Seals and shields provide additional protection for the bearing components and help to improve and maintain lubrication.
  • In terms of sealing performance, sealed bearings rank best, followed by shielded bearings and finally open bearings.

Deep groove ball bearings are available in a large number of sizes with different seals, shields, cages, and greases.

Successful mounting is critical to the life cycle of your bearing. Proper bearing dismounting can safeguard other machine components and maintenance workers.

The bearing is at the heart of all rotating equipment, and the condition of the bearing often reflects how well a machine is running. Learn more about bearing damage and bearing failure – and how to prevent it.
