In the field of precision machinery, bearings are the core framework of industrial civilization. They transform sliding friction into rolling friction, reducing the coefficient of friction by 95% (0.001 – 0.005 vs 0.08 – 0.12). The curvature radius error of the raceway of deep groove ball bearings is controlled at the micrometer level, supporting high-speed operation at 100,000 revolutions per minute.
Five core components working in synergy:
1. Ring structure
Forged from GCR15 special steel, with a hardness of HRC62, the wide inner ring design reduces foreign object intrusion by 70%.
2. Rolling Element Matrix
The tolerance of the steel ball diameter is ≤ 0.25 μm, and the plastic deformation of the wind power bearing after 2 million cycles is 0.18 mm.
3. Cage Optimization
The polyimide cage maintains a stability of 0.02mm at 300℃ and supports the spacecraft for 10 years without maintenance.
4. Contact Angle Design
A 15° contact angle triples the lifespan of four-point contact ball bearings, laying the foundation for the 2 million kilometer durability of high-speed railways.
5. Intelligent Lubrication
Nanometer additives maintain high-temperature consistency, and dynamic greasing reduces the risk of lubrication failure by 90%.
Precision manufacturing process:
18 processes in a 100,000-class clean workshop, forging at 1250℃ with spray cooling, quenching hardness gradient error ≤ 1.5HRC
An industrial big data platform monitors over 200 parameters, reducing the standard deviation of domestic bearing life to 3%
