 model four-point contact ball turntable bearing is one of the widely used parts, and almost all the bearing manufacturers and workers have dealt with it. Most colleagues think that turntable bearing is a very difficult "opponent", which is easy to crack in water quenching but not hard in oil quenching. The bearing is mainly used for assembling various mechanical equipment, and the large bearing is used in a rotating state, and the positioning direction of the machinery can also be changed; Small bearings are basically quenched and tempered. According to requirements, the bearings can also be tempered at low or medium temperature after quenching. With the development of national economy and the demand of export-oriented economy, 010.40.800 bearing is not only used to manufacture various components in engineering, but also can be used to manufacture low-grade optional parts, as well as slow cutting wire equipment and pig-raising equipment, and can also be used to assemble various hardware tools such as various machines, as well as various garden machinery and agricultural machinery tools. The following is a brief introduction to the production process and surface modification process of turntable bearings for reference by colleagues in the industry. I. Chemical composition, critical point of heat treatment and general process

Blackening treatment of small parts of bearing steel. The formula of blackening solution: NaOH (600 ~ 700g/L)+Nano2 (150 ~ 250g/L). The working temperature is 138~140ºC, and the blackening time is 45~60min. Blackening quality inspection: 1) visual inspection. Under the fluorescent lamp, the workpiece shall be observed 300mm away from the naked eye, and the color shall be uniform black, without obvious spots. 2) Density check. Immersed in the standard solution CuSO4·5H2O for 1min (room temperature), and it is judged as qualified if there is no Cu precipitation. 3) Inspection of antirust ability. The blackened parts were taken out in 30g/L NaCl aqueous solution at 20ºC for 10min, and exposed in the air above 20ºC for 2 hours. After visual inspection, they were qualified if they were completely rust-free. 4) Inspection of corrosion resistance. The blackened parts were taken out in 50g/L oxalic acid solution at 20ºC for 8min, and the surface colors were brown, dark gray and dark green.
