The SINOFOU solid ring needle roller bearing is composed of one or two rings and needle roller group with cage. It has smaller volume and higher bearing capacity. Therefore, the bearing can meet the requirements of light weight, small space occupation and large power transmission. Depending on the application, bearings with or without inner rings can be used.
