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.
