Why are thrust bearings generally not provided in cantilever centrifugal pumps?
Thread Content
Sir, why aren’t thrust bearings installed in cantilever centrifugal pumps? Are radial bearings the only ones used?
Cantilever centrifugal pumps also have thrust bearings; usually, there are thrust bearings placed back to back at one end, while at the other end there are supporting cylindrical roller bearings. When no thrust bearings are used, it is usually pumps with relatively low axial forces, but deep groove ball bearings are still employed to balance the axial force
The rear bearings of cantilever centrifugal pumps are usually angular contact ball bearings such as 73**, 72**; they are used in pairs. If you’re not sure, just search on Baidu! Smaller pumps will use deep groove ball bearings. At the front end, cylindrical roller bearings are generally used for radial positioning. NU…N series
Centrifugal thrust bearings are generally used, with two or three 73...becbj or 72becbj bearings at the front, and a radial bearing of the NU series at the back
