I hope to open the Japanese NSK bearing packaging just before the installation. General grease lubrication, do not clean, directly filled with grease. Lubricating oil is lubricated, and cleaning is not usually necessary. However, for instruments or high-speed bearings, Japan NSK bearings, etc., should be washed with clean oil to remove the rust inhibitor coated on Japan NSK bearings. The Japanese NSK bearing with the anti-rust agent removed is easy to rust, so it cannot be left alone. In addition, Japanese NSK bearings that have been sealed with grease can be used directly without cleaning.
The installation method of NSK bearings in Japan varies with the structure, fit and conditions of NSK bearings in Japan. Generally, because most of the shaft rotates, the inner ring needs an interference fit. Cylindrical hole Japanese NSK bearings are usually pressed in with a press or hot-packed. In the case of a tapered hole, install it directly on the tapered shaft or use a sleeve.
