The starting torque of the bearing refers to the minimum torque required when the bearing starts to operate, and is also one of important indexes of the performance of the bearing. In general, the smaller the starting torque of the bearing, the smaller the friction coefficient of the bearing, the smaller the friction loss and the higher the efficiency of the mechanical device. The starting moment is a rotation moment which is generated during starting and can overcome the resistance generated by static friction and the load driven by the static friction.
