Japanese NSK bearing processing characteristics

Processing characteristics of Japanese NSK bearings
The processing characteristics of Japanese NSK bearings are crucial to the use of bearings in different fields. Therefore, many manufacturers will also seek the processing characteristics of Japanese NSK bearings. Secondly, the precautions for processing and production of Japanese NSK bearings are undoubtedly a very important step. Therefore, based on the understanding of Japanese NSK bearings, tell you about the processing characteristics of Japanese NSK bearings and the precautions for related processing and production.
1. Forming processing
The working surfaces of bearing parts are all rotary forming surfaces, which are suitable for processing by forming methods. For example, the forging, rolling and grinding of the raceway of the ferrule are all processed by forming tools or anti-profile plates.
2. Precision processing
Most of the surfaces of Japanese NSK bearing parts must be ground, and the grinding size and geometric accuracy are in μm. In particular, the raceway and rolling element of the ferrule have higher precision and require superfinishing or grinding.
3. Multi-process processing
The requirements for bearing parts are high, and there must be many production processes. Generally, 20 to 40 processes are required for bearing production, and as many as more than 70 processes.
In addition, the vast majority of Japanese NSK bearings are standardized products, and the demand for bearings of the same model is very large. In order to improve productivity, reduce costs, ensure quality, widely adopt new technologies, and improve mechanization and automation levels, bearings are generally produced in large quantities according to bearing models and varieties, and even special automatic lines or assembly lines can be established for production.
