1. Introduction of bearing adapter sleeve

Adapter sleeves are the most commonly used components for bearings with tapered bores when locating on cylindrical shafts, as they can be used on plain or stepped shafts.

This bushing 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 accurately positioned in the axial direction, and the withdrawal of the bearing is also convenient.

2. Application of bearing adapter sleeve

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.

3. Structural composition of bearing adapter sleeve

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.

4. The difference between the bearing adapter sleeve and the withdrawal sleeve

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.

5. Marking of bearing adapter sleeve

The mark of the adapter sleeve is represented by the Latin letter H and Arabic numerals. The Arabic numerals represent the size series code and the applicable bearing nominal inner diameter code respectively from left to right. An example is shown in Figure 1. [1]

Adapter sleeves suitable for uranium bearing inner diameter 40mm and size series 23 are:

Product Description:

SLEEVES:

A roller bearing having a tapered bore is mounted on a straight shaft using either an Adapter Sleeve assembly, or a Withdrawal Sleeve. Mounting a bearing on a sleeve also permits maximum flexibility in the axial positioning of the bearing on the shaft and can accommodate light locational thrust loads.
An Adapter or a Withdrawal Sleeve mounted bearing requires the correct reduction of Radial Internal Clearance of the bearing so as to prevent relative motion amongst the bearing inner ring, the sleeve and the shaft. Non-compliance with proper mounting procedures will invariably lead to hot running of the bearing and subsequently to it's premature failure.
Both 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.

MATERIAL :

The Sleeves should be made from Carbon Steel as per established International Standard
Imported XSY Sleeves are manufactured from originally processed raw material (C20/C30) and machined in CNC machines to achieve the required machining accuracy and the surface finish, so that contact area is fully maintained to provide projected service life to the Bearing.
