There are many series and forms of seated rolling bearings. By selecting and using the most suitable seated bearing, the reliability of the mechanical device can be improved. * Triple sealed bearing series * With dust cover assembly series is waterproof and dustproof. * The heat-resistant and cold-resistant series can be used at high and low temperatures. * The purification series is small and light. * Stainless steel series are not easy to rust, water and chemical resistance * Cast steel series tough bearing box * Pottery bead series can be used in special environments such as water, medicine, high temperature and high speed.
