Q:How to install the tensioning sleeve

On the surface of the cleaned expansion sleeve and the surface of the joint, evenly apply a thin layer of lubricating oil. 3. Push the connected parts to the shaft to reach the position specified in the design. 4. Smoothly load the expansion sleeve of the loosened screw into the coupling hole, to prevent the tilt of the joint, and then tighten the screw by hand
Q:How to maintain the expansion sleeve
A:
1. After installation, apply a layer of anti-rust grease to the exposed end face of the expansion sleeve and the head of the screw. 2. On machines that work in the open air or have a poor working environment, anti-rust grease should be applied to the upper end face of the exposed expansion sleeve regularly. 3. The expansion sleeve that needs to work in the corrosive medium should take special protection (such as a cover plate) to prevent the expansion sleeve from rusting.
