The adapter sleeve is the most commonly used component when positioning bearings with tapered holes on cylindrical shafts. It is characterized by easy installation and does not require additional fixing on the shaft. This bushing can be used for both smooth shafts and stepped shafts. When an adapter sleeve is used on a smooth shaft, the bearing can be positioned at any position on the shaft; when used with a stepped ring on a stepped shaft, the bearing can be accurately positioned axially, and it also facilitates the removal of the bearing. Adapter sleeves are widely used in textile, light industry, papermaking, metallurgy, belt transportation and conveying equipment industries.

The installation steps of the adapter sleeve are as follows:

1. Clean the workbench and installation location to ensure the surface is flat and clean. 

2. Install the bearing sleeve on the shaft, ensuring the correct direction and position. 

3. Use the bearing sleeve installation tool or a light hammer to gently tap the bearing sleeve until it is completely installed on the shaft. 

4. Check whether the bearing sleeve is installed correctly and make sure it fits the shaft completely and is not skewed or misaligned. 

5. If necessary, apply appropriate lubricant to the bearing sleeve and shaft to ensure smooth operation. 

6. Carry out a final inspection to ensure that the bearing sleeve is installed correctly and is not loose.
