TECHNICAL INFORMATION

Both ball and roller thrust bearing require a minimum axial load to ensure a proper arrangement of balls/rollers along each raceway. In the case of ball thrust bearings operated at higher speeds, centrifugal forces and gyroscopic moments can have detrimental influence on the balls, i.e. sliding movements between the raceways and balls.
