We are committed to providing users with high-quality products and the best solutions, determined to be your best partner, and hope to make positive contributions to the development of the Composite Thrust Washers, Hydraulic Cylinder Guide Rings Excavator Spare Parts, PTFE Wear Strips industry. We are full of energy to meet the challenge of occupying the industrial highland in the future. We hope to achieve the grand goal of leaping from domestic large enterprises to large companies and enterprise groups with international competitiveness.
Our piston wear rings are composed of phenolic resin reinforced with ultra strong special fiber, added with solid lubricants, processed under certain temperature and pressure. Compare to other fiber-reinforced (cotton fiber, polyester fiber, polyamide fiber and so on) phenolic products, this material has the largest compressive strength, it is suitable used as back-up rings for mine, coal machinery and equipment.
