Contact SupplierBoth the Adapter and the Withdrawal Sleeves have cylindrical bore and tapered outer surface, with threading on one side of the outer surface, and are slit along the length. While the Adapter Sleeve has the threading on the small diameter side of the taper, the Withdrawal Sleeve has the threading on the larger diameter side. Thus, the Adapter Sleeve facilitates easy mounting of the bearing, while the Withdrawal Sleeve is normally used to ensure easy dismounting of the bearing, hence it's name.
An Adapter Sleeve assembly consists of the Sleeve, a Lock Nut and a Lock Washer, because the Lock Nut is needed first to drive the bearing up the tapered sleeve, and then to lock it in position with the help of the Lock Nut. A Withdrawal Sleeve, on the other hand, does not necessarily need the Lock Nut and the Lock Washer for it's assembly with the bearing and the shaft, and hence is supplied without them. However, a Withdrawal Nut may required to remove the Withdrawal Sleeve from the bearing, and in that case, it has to be ordered separately.
