Description

We use advanced production equipment and the latest technology to ensure a longer service life of our Slideway Soft Strips, Piston Guide Rings, Hydraulic Wear Ring for Piston and Rod. The company insists on seeking development through innovation, and has established a high-tech product research and development center with a group of high-quality professionals. We are dedicated to absorbing and updating the latest technology and we use it to our products promptly. Our company has a strong R&D team, excellent technical production personnel, and scientific and perfect management methods to provide customers with fast and convenient services.

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.
