Components of Adapter Sleeves

    Adapter sleeves: are used to mount bearings with tapered

bore onto a flat shaft (maximum tolerance H10), without the

need of a shoulder. The complete set comes with 3 parts: a

sleeve, a nut and a lock washer or MS locking device,

always supplied together.

    Withdrawal sleeves: are used to mount bearings with tapered

bore onto a cylindrical seat of stepped shafts. The shaft must

be threaded, so the nut can push the sleeve against the

bearing and the shoulder. The nuts are not supplied with the

sleeves and must be ordered separately.

    Lock nuts are accessories for the sleeves, but they also have

their own application where bearings need to be located onto

a shaft.

    Lock washers are an accessory for sleeves but they also have

their own application. Their main purpose is to lock the KM

and KML nuts preventing them from being released from the

sleeve or the shaft itself.
