The adapter sleeve is one of the commonly used bearing attachments, it is the most commonly used component for positioning a bearing with a tapered bore on a cylindrical shaft, because it can be used for either an optical or stepped shaft.
Many people may not know much about the adapter sleeve. Today, Isutami is here to tell you what is the difference between the adapter sleeve and the withdrawal sleeve.
Adapter sleeves and withdrawal sleeves are generally suitable for large bearings. The adapter sleeve is used to tighten the round nut to tighten the bearing, and the withdrawal sleeve is reversed.
The original intention of the adapter sleeve and the withdrawal sleeve is to facilitate the installation and disassembly of the bearing, improve the efficiency, and reduce the maintenance cost of the machine. In layman's terms, the adapter sleeve is used for easy installation, and the withdrawal sleeve is used for easy disassembly. And the use of the withdrawal sleeve and the adapter sleeve can achieve the effect of adjusting the internal clearance.
The adapter sleeve is convenient for adjusting the axial positioning of the bearing, and has better self-locking property. The use of the optical axis avoids the stress concentration phenomenon of the stepped shaft, and is beneficial to the use of heavy-duty transmission or shock vibration.
Although the structure of such a bearing device is simple, satisfactory results can be obtained only under the correct installation and maintenance. Otherwise, it will not be fast or even counterproductive.
