WR Custom Wear Rings
The Chesterton WR-Custom wear rings are tailor-made bearing bands designed to provide precise fit and optimal protection in hydraulic and pneumatic cylinders. Machined to your exact specifications, these rings prevent metal-to-metal contact, reduce side loading, and support smooth rod and piston movement even under heavy-duty conditions.
Fabricated from high-strength engineered polymers and available in a wide range of materials for chemical and temperature resistance, WR-Custom rings offer built-in lubrication and exceptional wear performance. They are ideal for upgrading worn cylinders or matching unique hardware profiles—helping extend equipment life, improve seal performance, and reduce maintenance across diverse industrial applications.
