Product Description

WR Wear Ring (Guide Ring) is designed to guide the piston and piston rod inside the hydraulic cylinder, absorb lateral loads, and prevent metal-to-metal contact between sliding components. Manufactured from grey fabric-reinforced phenolic resin, it delivers excellent wear resistance, high compressive strength, and stable dimensional performance under heavy load conditions.

Key Features
  • High Wear Resistance: Phenolic resin fabric backing ensures long service life under continuous sliding motion.
  • Pressure Resistant: Withstands up to 45 MPa without permanent deformation or extrusion.
  • Low Friction Coefficient: Smooth operation, no stick-slip behavior, reduces system power loss.
  • Good Guiding Performance: Prevents metal-to-metal contact, protects seals from eccentric loading and damage.
  • Dimensionally Stable: Resists swelling and deformation when exposed to standard hydraulic oils.
  • Split Design Available: Split rings allow easy installation without disassembling the cylinder.
