I hope to pack NSK bearing packaging just before installation. General grease lubrication, do not clean, directly filled with grease. Lubricating oil does not need to be cleaned in general. However, NSK bearings for instrument or high-speed use should be cleaned with clean oil to remove the rust inhibitor coated on NSK bearings. NSK bearings with anti-rust agent removed are easy to rust, so they cannot be left alone. Furthermore, NSK bearings packed with grease can be used directly without cleaning. The installation method of NSK bearing varies with NSK bearing structure, fit and conditions. Generally, since most of the shaft rotates, the inner ring needs an interference fit. Cylindrical hole NSK bearings are usually pressed in by a press or hot-fitted. In the case of a tapered hole, install it directly on the tapered shaft or use a sleeve. When it is installed to 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 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 NSK bearing. Therefore, appropriate anti-rust measures are required.
