The main function of support rollers is to provide support during the operation of mechanical equipment, reduce friction and wear, and ensure the stable operation of the system. The performance and quality of support rollers have an important impact on the operating efficiency of the entire equipment, product quality and the service life of the equipment. Its design and manufacturing need to consider many factors, such as load size, working environment, speed requirements, etc.
