It is generally believed that rolling friction torque is related to contact surface roughness, elastic hysteresis, adhesion effects, and differential sliding. Matsuhara pointed out that when the roughness of the contact surface between two objects is at 1 μ Below m, there is almost no effect on the friction torque, so the effect of surface roughness can be ignored. It is believed that the rolling friction torque in overrunning clutches mainly comes from elastic hysteresis and adhesion effects, while the effects of micro sliding and plastic hysteresis are relatively small and can be ignored. Holling also has the same view, so only the power consumption caused by elastic hysteresis and adhesion effects is analyzed and studied, regardless of the impact of factors such as contact surface roughness and differential sliding.

A roller bearing is a type of bearing in which the journal rotates in circumferential contact with many rollers typically mounted on a locating ring. Roller bearings can achieve good accuracy and rigidity through preloading. Also, an inner ring with a taper can be used to arbitrarily adjust the working clearance of the bearing. This solution can fully meet the demand for zero clearance of the printing machine cylinder bearings.
