2RS is a two-sided rubber seal, 2RZ is a two-sided dust cover seal, one is contact and one is non-contact. The 2RS is less noisy, but the accuracy is not too high to reach the P5 level. The basic dimensions of both bearings are the same. Can be universal depends on your application, 2RS sealing effect is better than 2RZ, but the friction resistance is slightly larger. If it is required to seal well, if it does not leak oil, it is best to use 2RS. The 2RS is less noisy, but the accuracy is not too high to reach the P5 level.

In the actual production and processing process, in addition to the structure and quality of the bearing itself, it is related to the coordination of grease and bearings, and some motors will be very flexible after rotation for a period of time after starting; For manufacturers with conditional monitoring data, the most intuitive is the fact that no-load current and no-load loss will vary from large to small and tend to be stable with the rotation of the motor.
Individual customers will control the downtime of the motor, and it can be found from the test data that the efficiency of the motor with a relatively long downtime is better than that of the motor with a relatively short downtime.
