Mechanical products are becoming more diversified with the continuous development of precision processing and materials technologies.The friction force generated by the O-ring seal in a hydraulic cylinder was once considered redundant.However, its utilization here has recently been proposed.

The hardness of the O-ring and the inner diameter of its groove directly affect the normal pressure between the O-ring and the inner wall of the cylinder, thereby affecting the friction behavior.In order to explore this friction behavior, a strain-based friction force measurement system is developed in this study, and the steady-state and dynamic friction values under different working conditions are studied and discussed in depth.This research on the friction behavior in the cylinder provides a theoretical basis for more convenient design and utilization of click here the friction force generated between the O-ring and the inner wall of the cylinder.
