Wear Rings

WR Custom Wear Rings

 Chesterton Custom Wear Rings (WR) are the solution to costly cylinder remachining and repairs for pneumatic and light- to heavy-duty hydraulic equipment. These split, replaceable wear rings reduce probability of metal-to-metal contact of moving parts and help prolong equipment life. When installed during the cylinder repair, the risk of recurring damage is significantly reduced. The easy-to-use split WR designs are manufactured from various engineered plastic materials to provide the best possible bearing solution based on operating condition and hardware configuration. Utilized plastic compounds have good bearing capacity and are capable of supporting transverse loads. These bearings reduce radial movement therefore helping to extend seal life. The use of nonmetallic wear rings helps to prevent the buildup of hydrodynamic pressure in small clearances of the cylinders and helps to prevent diesel effect. Each seal is individually manufactured from our unique machining process which eliminates the need for tooling costs associated with new sizes. The precise CNC lathe manufacturing technology of the WR provides accurate dimensional and geometrical tolerances, and improved fitting. Flexible manufacturing technology allows to virtually produce any size and shape thus providing retrofit bearing solutions. Various designs and materials are available including the WR, P9KL, R9KL, WRTP, WRTR, WRUP, and WRUR which address specific needs and applications in the market.
