Precision bearings are the core component materials used in high-precision equipment: high nitrogen bearing steel (containing 1% carbon and 1.5% chromium) is treated with nitriding to improve corrosion resistance, and its rolling fatigue life is three times that of ordinary steel
Ceramic rolling elements use silicon nitride to optimize high-speed performance
Tolerance control: The matching parts (shafts, seat holes) need to achieve an accuracy of within 1 μ m, and the interference fit should be accurately calculated to avoid error amplification
During assembly, a dedicated device is required to achieve vertical positioning and conduct dynamic balance testing
