The function of the wear-resistant ring is to provide guidance and support for the piston and piston rod of the hydraulic cylinder, and to absorb radial loads; At the same time, it can prevent metal contact between the moving parts of the oil cylinder, such as the piston and cylinder barrel or the piston rod and cylinder head. Compared with traditional metal wear-resistant rings, non-metallic wear-resistant rings have the following obvious advantages:
1. Wear resistant rings have low production costs, high load-bearing capacity, and eliminate local stress concentration.
2. Good wear resistance, long service life, metal/plastic pairing, eliminating mutual wear, and excellent friction.
3. The wear-resistant ring can absorb and attenuate mechanical vibration, has a good wiping effect, and can adsorb small foreign particles.
4. Simple enclosed grooves, easy to install, and low maintenance costs.
