Bearing lubricant supply

It is hoped that the bearing package will be opened just before installation. General grease lubrication, do not clean, directly filled with grease. Lubricating oil does not need to be cleaned in general. However, the bearings for instruments or high-speed use should be cleaned 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, since most of the shaft rotates, the inner ring needs an interference fit. Bearings with cylindrical bores 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 use a sleeve.

When installing to the shell, generally there is 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.

Bearing storage

Bearings are coated with a proper amount of anti-rust oil and packed with anti-rust paper when they leave the factory. As long as the packaging is not damaged, the quality of the bearings will be guaranteed. However, for long-term storage, it is advisable to store it on a shelf 30cm above the ground under the condition that the humidity is lower than 65% and the temperature is about 20℃. In addition, the storage place should avoid direct sunlight or contact with cold walls.
