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.

Product application
Kintowe piston wear rings guide pistons and piston rods in a hydraulic cylinder, minimizing transverse forces and preventing metal-to-metal contact. Use of wear rings reduces friction and optimizes the performance of piston and rod seals.
