Bearing Adapter

Product Detail Information

Bearing Adapter

-. Adapter sleeve (H)

Adapter sleeves are the most commonly used components for locating bearings that has a tapered bore, onto cylindrical shaft seating’s as they can be employed both on smooth shafts and stepped shafts.

They are easy to mount and require no additional fixation on the shaft. Using adapter sleeves on smooth shafts, the bearing can be located at any position on the shaft . EESCO adapter sleeves are supplied complete with lock nut and locking device.

   

-. Adapter sleeve for oil injection (OH)

These sleeves have an oil supply duct (or ducts) at the threaded side of the sleeve and distributor grooves in the bore as well as the outside surface.

Sleeves up to and including size 40 have on supply duct, larger sleeves have two.

Withdrawal sleeve (AH,AOH)

-. Withdrawal sleeve (AH)

Withdrawal sleeves can be used to mount bearings with tapered bore on cylindrical seating’s of stepped shafts. The sleeve is pressed into the bore of the bearing that abuts a shaft shoulder or similar fixed component. The sleeve is located on the shaft by a nut or an end plate. The sleeves are slotted and have an external taper of 1:12 or 1:30.

   

-. Withdrawal sleeves for oil injection (AOH)

These AOH sleeves have two oil supply ducts at the threaded side as well as oil distributor grooves in the circumferential and axial directions, both in the outside surface and the sleeve bore. If oil is injected through these ducts and grooves, an oil film is formed between the mating surfaces of the bearing and sleeve and between the shaft and sleeve, and the force required to mount the bearing is considerably reduced.
