Product Parameters

The material of bearing ring parts shall be high quality refined bearing steel GCR15 and other grades of bearing steel, and the rolling body shall be made of GCR15 bearing steel or ceramic.
According to different contact angles, bearings can be divided into three types: 7000C (15 °), 7000AC (25 °), 7000AA (26 °), and 7000B (40 °). Bearings with different contact angles can be produced according to user requirements.
