Use of pump bearings
Thread Content
Pump bearings are classified into radial bearings and thrust bearings based on the direction of the forces they bear. So, do small pumps use radial bearings or thrust bearings? I don’t quite understand. Please explain, thank you
Small pump motors typically use radial bearings. Radial bearings can withstand the radial forces as well as part of the axial forces generated by the water pump, while thrust bearings are primarily used to handle the axial forces produced by the water pump. Since the axial force of small pump motors is low, radial bearings are generally sufficient to meet the requirements. Of course, the specific type of bearing to be used depends on the design and requirements of the pump. .
Many bearings can withstand both radial and axial forces simultaneously (such as cylindrical roller and deep groove ball bearings); it’s merely a matter of the magnitude of the forces they can handle. Such bearings are typically used in small pumps.
