grease lubrication, do not clean, directly fill with grease. For lubrication with lubricating oil, it is not necessary to clean in general. However, bearings for instrument or high-speed use shall be cleaned with clean oil to remove the antirust agent coated on the bearings. The bearing with rust inhibitor removed is easy to rust, so it can not be placed regardless. Moreover, bearings sealed with grease can be used directly without cleaning.

 

The installation method of bearing varies according to the bearing structure, fit and conditions. Generally, the inner ring needs interference fit because it is mostly shaft rotation. Cylindrical bore bearings are usually pressed in with a press or hot installed. In the case of taper hole, it can be directly installed on the taper shaft or installed with sleeve.

 

When it is installed on the shell, there is usually more clearance fit, and the outer ring has interference. It is usually pressed in by a press, or there is a cold shrinkage fit method for installation after cooling. When dry ice is used as coolant and cold shrinkage is used for installation, the moisture in the air will condense on the surface of the bearing. Therefore, appropriate anti rust measures are required.
