In the application of machine tool precision bearings, the carrying capacity is not most important when selecting the size of the bearing, and the rigidity, speed and accuracy is determine the factor. However, when the type of the bearing is selected, the size and direction of the load should be considered. In general, in the case of the substantially dimension, the load amount of the roller bearing is higher than the ball axis.
Radial load: Double column cylindrical roller bearing inner ring in the sample does not have a baffling, and can only withstand radial load, angular contact ball bearings and tapered roller bearings to withstand radial and axial joint loads.
