Description

We strive to ensure that our Filled PTFE Tubes, Glyd Rings, Slideway Soft Strips meets the needs of the world, including not only manufacturing products, but also service and support and other businesses we are involved in. We will, as always, provide our customers with efficient, convenient and high-quality services. It is our constant pursuit to improve the core competitiveness of enterprises and build industry advantages. We emphasize the close integration of work and learning, so that every employee can find their own development direction and promotion path.

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.
