18K/19K Split Wear Rings
- Wear Rings for Hydraulic and Pneumatic Applications
Chesterton replaceable Bearing Bands are the solution to costly cylinder re-machining and repairs for hydraulic or pneumatic equipment. These split, replaceable bearing bands minimize 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). These bearings reduce radial movement, helping to extend seal life. These designs are suitable for use on rods, rams, or pistons in reciprocating, rotary, or static applications due to their exceptional physical properties and built-in lubricants.
