Wear Rings

Chesterton 19K Wear Rings

Chesterton replaceable wear rings are the solution to costly cylinder remachining and repairs for medium- to heavy-duty hydraulic or pneumatic 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 18K and 19K designs are manufactured from a glass fiber-reinforced thermoplastic polyimide resin (heat stabilized nylon) for high bearing capacity and are capable of supporting transverse loads. These wear rings reduce radial movement therefore helping to extend seal life. The exceptional physical properties allow for use in a broad range of temperature conditions and provide excellent fluid compatibility. The built-in lubricants help to reduce friction between mating surfaces and reduce risk of fretting and seizing, which further provides good dry running capabilities. 18K and 19K wear rings have excellent dimensional stability. 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. The precise manufacturing technology of the 18K and 19K wear rings provides accurate dimensional and geometrical tolerances, and improved fitting. According to industrial standards sizing, the 18K and 19K are a direct retrofit to existing wear ring grooves which eliminates the need for equipment modification. The split design makes the installation of the cut wear rings easy (snap-in fitting), allowing them to universally use on either rods, rams, or pistons in reciprocating applications.
