Wear Rings

Wear rings are non-metallic guide elements used in hydraulic and pneumatic cylinders. They keep the piston or rod aligned, reducing side loads on seals. Made from materials like phenolic resin, polyester, or PTFE composites, wear rings resist abrasion, high pressure, and temperature. They are used in construction machinery, presses, injection molding machines, and other heavy-duty systems. By preventing metal-to-metal contact, they extend the life of both seals and cylinder components.
