Installation Tips for One-way Roller Bearings

If the contents of one-way bearings are burrs, iron chips, dust and other foreign objects entering, it is necessary to ensure that the exterior of the device and the installation environment are clean. This causes noise and vibration of bearings while running, and can even damage the raceways and rolling bodies.

Because one-way bearings must be cleaned before the unit leaves the factory. In order to maintain that the track and rolling body surfaces are not rusted, rust-proof oil or rust-proof grease is injected between the raceway and the rolling body. Therefore, it is necessary to clean gasoline and kerosene cleaning, and then apply clean, high-quality or high-temperature lubricants to use. However, some fully enclosed bearings and bearings coated with grease that are lubricated and rust-proof, the cleanliness that do not require cleaning has a very large effect on bearing life and vibration noise.

Different types and the same type of different grades of grease performance varies greatly, to choose the correct grease. Grease is made of base oils, thickeners and additives. The permissible rotation limits are different, and the performance of the grease is also determined by the base oil thickener is also related to lubrication performance, thickener water resistance determines the water resistance of the grease. Generally low viscosity base oil is suitable for low temperature, high speed, high viscosity is suitable for high temperature, high load. Different brands of grease can not be mixed and even the grease of the same thickener can have a bad effect on each other due to different additives.

Since only the inner ring is heated, the advantages of heating with an induction heater: the bearing can be heated quickly, reliably and cleanly to the desired temperature. The outer ring is less heat-exposed, which can be easily mounted on the shaft and easily loaded into the seat hole.
