Withdrawal Sleeve are suitable where bearing with the tappered bore are to be located on cylindrical shafts. The tapered sleeve is pressed into the bearing bore until the required reduction in radial internal cleaerance is achieved. The bearing is abutted, for example against a shoulder on the shaft. The tensile strength of material atleat 430N/mm2. The outside surface of the sleeve has a taper of 1:12, in series AH240 and AH241 tapper is 1:30.

Locknuts can be used to fix bearings on shaft or adapter sleeve they also give a easier mounting of bearing with a tapered shaft seat and the fitting and dismantling of the bearings on sleeves.Locknuts are made from steel and the tensile strength of the material is atleast 350 N/mm2. They have four or eight evenly spaced slots on the circumfrence into which hook renches or strinking face renches can be fitted.

Locking Washer MB and MBL are simple,reliable element for securing smaller locknuts.They have an tab and outer several tabs.Evenly spaced around the circumfrence.The inner tab grips on the adapter sleeve or the shaft,one of the outer tab is bent to give location in the slot of the nut. These plates are made from steel and tensile strength of the material used is 300 N/mm2.

Hydraulic Withdrawal sleeve is used in fitting and dismantling of large bearings requires high mounting forces and is made easier by using the Hydraulic Withdrawal Sleeve. There are Hydraulic Withdrawal Sleeve with oil slots on the tapered outside surface and to pump connectors offset to each other by 90 degree.

Hydraulic Adapter Sleeve is used in fitting and dismantling of large bearings requires high mounting forces and is made easier by using the hydraulic adapter sleeve. There are adapter sleeve with oil slots on the tapered outside surface and a pump connector on the thread side.

Adapter Sleeve are suitable where bearing with tappered bore are to be located on cylindrical shaft they require no additional means of securing of the shaft the bearing can be postioned at any point of smooth shaft. This also simplifies dismentling of bearing. Adapter sleeve compromise slotted adapter sleeve, locking nut and retaining plates. For larger sizes retaining brackets are used instead of retaining plates. The tensile strength of material atleat 430N/mm2. The outside surface of the sleeve has a taper of 1:12, in series H240 and H241 tapper is 1:30.
