Whether the bearing is installed correctly affects the accuracy, life and performance. Therefore, the design and assembly department must fully study the bearing installation.HONBbearing07
Hope to install in accordance with operating standards. The standard operation items are usually as follows :
1.Clean the bearing and its related parts
2. Check the size and finishing of related parts
4. Inspection after bearing installation
5. Supply lubricant
Before installation, open the package. General grease lubrication, do not clean, directly filled with grease. Lubricating oil is lubricated, and cleaning is not usually necessary. However, the bearings for instruments or high-speed applications should be washed with clean oil to remove the anti-rust agent coated on the bearings. Bearings with anti-rust agent removed are easy to rust, so they cannot be left alone. In addition, bearings that have been packed with grease can be used directly without cleaning.
The installation method of the bearing varies with the bearing structure, fit, and conditions. Generally, because most of the shaft rotates, the inner ring needs an interference fit. Cylindrical bore bearings are usually pressed in with a press or hot-fitting method. In the case of a tapered hole, install it directly on the tapered shaft or install it with a sleeve. When it is installed on the shell, there is generally a lot of clearance fit, and the outer ring has an interference. 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 the coolant, the moisture in the air will condense on the surface of the bearing when the shrink fit is installed. Therefore, appropriate anti-rust measures are required.
