In the past, only the radial force generated by the radial lip of the oil seal can be measured by a radial force instrument, but the axial force generated by the axial lip cannot be measured. The axial lips generate larger friction force under a certain interference condition, so that the influence of friction torque is formed, and particularly, the bearing oil seal with a plurality of axial lips has larger influence of friction torque. Under the requirements of energy conservation and consumption reduction, the friction torque generated in the axial direction also needs to be controlled. In the past, the axial force of the oil seal is limited by space and precision thereof, and no good detection device exists.
