Quick Reference
Electric motors and water pumps are the backbone of African agriculture and light industry. The C3 internal clearance specification is critical for motors running at high temperatures — standard clearance bearings will seize under thermal expansion. These 6 models cover the vast majority of motor and pump applications from 25mm to 40mm shaft diameter.
