Feature: 1. This type bearings are particularly versatile. 2. They are simple in design, non-separable, suitable for high and even very high speeds and are robust in operation, requiring little maintenance. 3. Deep raceway grooves and the close conformity between the raceway grooves and the balls enable deep groove ball bearings to accommodate axial loads in both directions, in addition to radial loads, even at high speeds. 4. According to the design, there are the open basic open design bearings, the sealed bearings, the oil-selaed bearings, the bearings with the snap ring groove, and the bearing with or without snap ring, and so on. 5. The bearings are used in a particularly wide variety of applications.
