The function of the roller is to support the weight of the conveyor belt and the material. The roller must operate flexibly and reliably. Reducing the friction between the conveyor belt and the roller plays a key role in the life of the conveyor belt, which accounts for more than 25% of the total cost of the conveyor.
It accounts for 35% of the total cost of a belt conveyor and generates more than 70% of the resistance, so the quality of the roller is particularly important.
Advantage Ball Bearing Manufacturing Base is located in Cixi, the gathering place of China's bearing industry. The enterprise consists of two production plants, one focusing on the production of general grade ball bearings, and the other dedicated to the manufacture of EMQ high-quality bearings that meet the stable Z3V3 standard. The factory spares no effort to introduce the world's leading bearing manufacturing technology and equipment, and widely adopts CNC automated production lines, which is now among the most advanced equipment and technology in China's bearing manufacturing industry. The ball bearing manufacturing division of Granville offers a comprehensive range of radial deep groove ball bearings covering open, shielded, sealed, chrome steel and stainless steel materials to meet the needs of different customers.
