What Is Breakout Torque?
Breakout torque (also known as break out torque or break-out torque) refers to the amount of torque required to initiate relative rotation between a rotary shaft and a seal or bearing, and plays a key role in systems that involve oscillatory movement. Breakout torque is a function of both the inertia of the mechanisms involved and static friction. In ball bearings, you will often see it referred to as the starting torque, and there it refers specifically to the amount of torque required to start the rotation of one ring of the bearing.
