What are the factors that must be considered in the selection of stainless steel bearings?


Limit speed:
The limit speed, which is the maximum allowable operating speed of the bearing. Beyond this limit, the operating temperature of the stainless steel bearing will continue to rise, and the lubricant will dry up, so that the bearing is stuck, so the limit speed of the selected bearing is 10% higher than the predetermined maximum working speed of the bearing.

Use environment:
Stainless steel bearings can be rust-proof to a certain extent, but when the bearings are in a very harsh corrosive environment, such as strong acid and alkali liquids, ordinary stainless steel bearings cannot be completely rust-proof, and bearing rust easily causes the bearings to become stuck, so it is necessary Choose stainless steel bearings of different materials depending on the environment in which they are used.

Operating temperature:
Stainless steel bearings used in high temperature environments require special handling. Usually, we will ask the customer about the operating temperature and the limit temperature in advance to avoid bearing jamming or affecting production due to excessive bearing running temperature.

When considering the load factor, it should be noted that the life of the stainless steel bearing is more sensitive to the load ratio than the rotational speed. When using the multi-stage transmission shaft, it is better to place the larger deceleration in the later stage; for the spindle bearing, the external load should be properly adjusted. The distance between the point and the bearing fulcrum is to reduce the load on the spindle bearing and to ensure that the load transmitted to the spindle bearing is stable and avoids shock and vibration.
