[0002] Bearings are an important component in mechanical equipment. Their main function is to support mechanical rotating bodies and reduce the friction coefficient during the operation of mechanical equipment. There are many types of bearings on the market, and different types of bearings are used on different mechanical equipment. During the production and processing of bearings, the inner and outer rings need to be polished to ensure the accuracy in later use. Therefore, the use of polishing devices is relatively common in bearing production.

Therefore, we propose an outer cylindrical grinding device for bearing production to solve the problems raised above. Utility Model Content
