Ball Bearings torque

Small diameter (< 20mm O.D.) deep groove ball bearings have extremely low and uniform torque characteristics. Even when preloaded as part of an assembly, average torque levels of less than 0.5 gm-cm (0.007 oz-in) are common. Typically, torque is dependent on many factors, including ball size, number of balls, retainer type and looseness, radial play, lubricant type and fill percentage, and applied load.
