The specific characteristics of poor hand feel of the servo WPWS80,WPWS100,WPWS120,WPWS135,WPWS155 planetary reducer bearings include: feeling impurities and blockage inside the bearings when rotating the rotor with your hand. Why does this problem arise? The manufacturer of the Babman servo planetary reducer analyzed it this way, which may be related to its excessive clearance, improper fit between the inner diameter and shaft, and channel damage. So, how should we solve this problem?
The lifespan of servo planetary reducers mainly depends on the lifespan of bearings, and generally speaking, bearings are the first to fail. And this can be divided into two situations: one is that even the best bearings cannot guarantee 100% of their lifespan; Another reason is that the bearings are indeed not good, and defects in materials or processes result in a shortened bearing life. There is a certain probability of early wear of bearings, and major manufacturers also acknowledge the occurrence of this situation. Early wear usually occurs in a few months to a year, depending on the operating conditions. However, there may also be differences in the probability between different brands. Generally speaking, the official answer is that the probability is within 10%.
