Heavy Load Excavator Bearing180x250x33mm BA180-4BWSA

The contact area between the rolling element and the inner and outer rings of angular contact ball bearings is relatively small, so their frictional resistance is relatively small and they can withstand higher rotational speeds. Under high-speed operation, angular contact ball bearings can still maintain good stability and accuracy, and are suitable for various high-speed mechanical equipment, such as high-speed machine tools, aviation engines, etc.
