BR2 boundary lubricated bearing is made of steel plate as the base, sintered spherical bronze powder in the middle, rolled polyoxymethylene (POM) modified on the surface, and oil storage pit. The utility model is suitable for the places with low speed and medium load under normal temperature, which can reduce the cost and prolong the service life by replacing the traditional copper sleeve. When it is used on the rolling mill, the frequency of oil filling can be saved and the replacement procedure can be simplified.
The product has been widely used in automobile chassis, forging machine tools, metallurgical mining machinery, engineering machinery, hydropower, steel rolling industry and other fields.
