Description

Since it was established , the company has always been committed to the research and development, manufacturing and application of high-quality Wear Pads, Fabric WR Wear Ring Hydraulic Cylinder Seal, Composite Material Wear Rings . With its professional mission and competitive prices, it provides successful companies with numerous reliable product series, which perfectly balances performance and price. The products are brought to every corner. Our philosophy is to provide one-stop service to our customers in order to reduce their efforts in supplier management. Our company is rapidly developing and growing based on the advantage of good geographical location and industrial heritage.

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.
