Accessories are standard machine components serving for fixing rolling bearings on the shaft or in the housing bore.
They are adapter sleeves, withdrawal sleeves, locknuts and withdrawal nuts, locking washers and snap rings for bearings with snap ring groove on the outer ring.
Adapter sleeves and withdrawal sleeves
Adapter sleeves and withdrawal sleeves are used for fixing bearings with tapered bore on cylindrical shaft. The sleeves facilitate bearing mounting and dismounting and they often simplify the arrangement design. Adapter sleeves are more common and their mounting is more simple than mounting of withdrawal sleeves. Bearings with the withdrawal sleeve need to be rested on non-rolling part, e.g. housing shoulder. Once the withdrawal sleeves are pressed into the bearing bore with a lock nut or lock plate they need to be fixed on the shaft.
Adapter sleeves are supplied complete with lock nut and locking washer. The sleeves are slotted and the outer part taper is 1:12. The dimensions of the adapter sleeves comply with ISO 113/I. standard. Adapter sleeves of bigger diameter are produced as standard with oil ducts at the threaded side and an oil distributor groove on the outside surface – designation OH…H. The sleeves with distributor grooves in the bore as well as the outside surface are designated OH…HB. The sleeves with an oil supply duct at the side opposite to the threaded section and a distributor groove in the outside surface are designated OH. The sleeves with a distributor grooves on the surface as well as the bore are designated OH…B.
Withdrawal sleeves are slotted and have a taper surface. Dimensions of the withdrawal sleeves comply with ISO 2982 standard. The withdrawal nuts are not included and they must be ordered separately. Withdrawal sleeves of bigger diameter are produced as standard with oil ducts at the threaded side and an oil distributor grooves on the outside surface as well as the bore – designation AOH.
Lock nuts and withdrawal nuts
Lock nuts are used for fixing the bearing inner rings on the adapter sleeves or directly on the shaft, eventually for mounting and dismounting the bearing on the withdrawal sleeves. Lock nuts are equipped with grooves on the outer diameter to facilitate the manipulation with them. Dimensions of lock nuts are in accordance with ISO 2982.
Locking washers, locking clip
Locking washers are used for fixing the lock nuts of smaller diameter and the locking clips are used for fixing the lock nuts of bigger diameter. Locking washers are made of a deep-drawing sheet steel and their dimensions comply with ISO 2982 standard. Locking clips are also made of a deepdrawing sheet steel and they are attached to withdrawal sleeve with a bolt. The bolt and the washer are included in the delivery.
