The Importance of Bearing Adapter sleeve

Adapter sleeve is the most commonly used component for bearings with tapered bores when locating on cylindrical shafts, as this sleeve can be used for plain or stepped shafts.

Adapter sleeve is easy to install and does not require additional fixing on the shaft. When using an adapter sleeve on an optical shaft, the bearing can be positioned anywhere on the shaft. When used together with a stepped ring on a stepped shaft, the bearing can be positioned accurately in the axial direction, and the withdrawal of the bearing is also convenient.
The adapter sleeve is used to fix the tapered hole self-aligning bearing (self-aligning ball bearing, self-aligning roller bearing) on the shoulderless shaft, with simple structure, reliable operation, convenient bearing replacement, widely used in textile, light industry, papermaking, Metallurgy, belt transportation and conveying equipment and other industries.
The adapter sleeve is composed of the adapter bush, lock nut, lock washer (or lock card) and other parts. Adapter sleeves with lock nut and lock washer are only interchangeable as a set. Spare parts from different sources are not interchangeable.

The adapter sleeve tightens the round nut against the bearing, and the withdrawal sleeve does the opposite. The specific implementation method is that the thread opening is different: the adapter sleeve is at the thin place, and the withdrawal sleeve is at the thick place.

The taper design of the bearing ring is designed to facilitate installation and disassembly, improve efficiency and reduce mechanical maintenance costs. In layman's terms, the adapter sleeve is used for the convenience of installation, and the withdrawal sleeve is used for the convenience of disassembly. It is simply understood that the adapter sleeve is an accessory of the inner tapered bore bearing, which can ensure the stable operation of the supporting bearing. The use of the withdrawal sleeve and the adapter sleeve can achieve the effect of adjusting the internal clearance.

(1) Bearing adapter sleeves are widely used in places where light loads are easy to disassemble. There are many bearings that will encounter difficulties in assembly and disassembly, especially the assembly of bearings inside the box is limited by conditions, and the application of bearing sleeves solves the assembly and disassembly problems.
(2) Because the bearing sleeve can be adjusted tight and loose, the machining accuracy of many boxes is relaxed, and the work efficiency of box machining is greatly improved.
(3) Pressing the sleeve to overcome the axial movement of the bearing through the friction between the shaft and the inner ring. Therefore, the bearing sleeve is widely used, but there are also some shortcomings, because the accuracy of the sleeve directly affects the radial runout of the shaft.
