Whether the bearings are installed correctly affects their accuracy, life and performance. Therefore, the design and assembly departments should fully study the installation of bearings. It is hoped that the installation will be carried out in accordance with the operating standards. The items of the operating standards are usually as follows:

(1) Clean the bearings and bearing-related parts

(2) Check the size and finishing of related parts

(3) Installation

(4) Inspection after the bearings are installed

(5) Supply lubricant

Before installation, open the package. Generally, grease lubrication is not cleaned and grease is directly filled. Lubricating oil lubrication does not need to be cleaned in general, but bearings for instruments or high-speed use should be cleaned with clean oil to remove the rust inhibitor applied to the bearings. Bearings with rust inhibitors removed are prone to rust, so they cannot be left alone. In addition, bearings that have been filled with grease should not be used directly without cleaning.

The installation method of bearings varies depending on the bearing structure, fit and conditions. Generally, since the shaft rotates, the inner ring needs an interference fit. Cylindrical bore bearings are usually pressed in with a press or hot-fitted. In the case of a tapered bore, they are directly installed on the tapered shaft or with a sleeve. When installed in the housing, there is usually more clearance and the outer ring has an interference fit. It is usually pressed in with a press, or there is also a shrink fit method for installation after cooling. When dry ice is used as a coolant, moisture in the air will condense on the surface of the bearing when shrink-fitting is installed. Therefore, appropriate anti-rust measures are required.
