The service life of the robot reducer bearing is mainly affected by the fatigue limit of the bearing material, speed, load, temperature and lubrication. Among them, the fatigue limit of the bearing material is one of the most important influencing factors. Therefore, in order to improve the service life of the robot reducer bearing, it is necessary to consider the following aspects:

1. Material selection: The selection of high-strength, corrosion-resistant and high-temperature resistant alloy steel materials can effectively improve the fatigue limit and service life of the bearing.

2. Structural design: Adopting a reasonable structural design, reducing the matching clearance between the inner and outer rings of the bearing, improving the stiffness and strength of the bearing, and helping to improve the service life of the bearing. 3. Lubrication treatment: Good lubrication treatment of the robot reducer bearing can reduce the friction and wear of the bearing and extend the service life of the bearing. Generally speaking, lubrication treatment is carried out by grease lubrication or oil mist lubrication. 4. Use and maintenance: The following points should be noted during the use and maintenance of special bearings for robot reducers: * Avoid damaging the surface of the inner and outer rings of the bearings during installation to avoid affecting the service life of the bearings; * Ensure sufficient lubrication during use to avoid affecting the normal operation of the bearings; * During maintenance, replace the grease in time, clean the bearing surface, and make necessary adjustments and inspections to the bearings.
