There are four main factors that must be considered in the selection of China 6800 Series Bearing products, namely limit speed, operating environment, operating temperature, and predetermined workload. You can choose suitable bearings according to these performance requirements.
First, the limit speed: that is, the maximum allowable working speed of the China 6800 Series Bearing. Exceeding this limit, the operating temperature of the bearing will continue to rise, the lubricant will dry up, and the bearing will be stuck, so the limit speed of the selected bearing should be 10% higher than the predetermined maximum working speed of the bearing.

Second, the use environment: China 6800 Series Bearing can prevent rust to a certain extent. When the bearing is in a very harsh corrosive environment, such as strong acid and strong alkali liquid, ordinary bearings cannot completely prevent rust, and the rust of the bearing can easily cause the bearing to be stuck, so the material should be selected according to the different use environments.
Third, operating temperature: The China 6800 Series Bearing products used in high-temperature environments needs special treatment. Usually, the manufacturer will ask customers about the operating temperature and limit temperature in advance to avoid problems such as the bearing stuck due to the high operating temperature of the bearing.
Fourth, working load: when considering load factors, it should be noted that the life of the China 6800 Series Bearing is more sensitive to load than to rotational speed. When using a multi-stage drive shaft, the larger deceleration should be placed in the later stage. For the main shaft bearing, the distance between the external load action point and the bearing fulcrum should be appropriately adjusted to reduce the load and avoid shock and vibration.
