中文简体2. Bearing steel: The material used in the motor bearing is above the national standard P0Z2 level. The dimensional accuracy is less than 0.01mm, the hand feel is smooth, the speed is less than 20000rpm, the noise is low, and the service life is long. Suitable for motors, toy models, automobiles, power tools, pneumatic tools, telecommunication equipment, fitness equipment, sports equipment, etc.
3. Bearing steel: high-quality bearing material, above the national standard P6 level.
The dimensional accuracy is less than; 0.005mm, it can replace the import, the hand feel is smooth, the speed is more than 20000rpm, the noise is low, and the service life is long. It is suitable for high-speed motors, high-speed models, instrumentation, precision equipment, high-end toys and other fields with high requirements. 4. Stainless steel bearings: divided into motor grade and high-quality grade, which are made of stainless steel 440C. The size, precision, and quality grade requirements are basically the same as those of bearing steel bearing motor grade and high-quality grade. The main difference is that stainless steel bearings are waterproof, rust-proof and anti- Corrosion, acid and alkali resistance, strong stability, maintenance-free, long service life, no rust.
- Widely used in food machinery, medical equipment, instruments and meters, high-end handicrafts, high-end fishing gear, fishing reels, high-end toys, etc. In addition, the material of stainless steel bearing 440C cannot be judged by whether it is magnetic or not. The material made of 440C is magnetic, and it is the last word that it does not rust. 5. Non-magnetic 304 stainless steel bearing: non-magnetic 304 stainless steel bearing, its acid and alkali resistance is better than stainless steel 440C material. However, due to the material characteristics, the hardness is soft, and its product feel and quality appearance are poor, and it is only suitable for low speed and low load use. Cannot be used on motors.
