The special bearing for vibrating screen is mostly used in mine vibrating machinery, vibrating screen machinery and vibrating motor, and is one of the key components of such equipment. The bearing is used in the environment with harsh working conditions, high humidity and heavy dust particles. According to the characteristics of load generated by the eccentric shaft of vibrating screen, SJQ developed a spherical roller bearing with better bearing capacity and impact resistance, which solved the temperature rise problem of the bearing in use.
