Overview:
Phenolic Wear Rings in WR Seal hydraulic cylinder seals are a key component widely used in hydraulic cylinders and pneumatic cylinders to guide pistons and piston rods and prevent direct metal-to-metal contact. Phenolic wear rings have the characteristics of high strength, good wear resistance, and strong dimensional stability, which can effectively extend the service life of hydraulic cylinders and improve the overall performance of the system.
Materials and Manufacturing
Phenolic wear-resistant rings are usually made of phenolic resin. This material is made by impregnating reinforcing materials such as cellulose fiber or glass fiber in phenolic resin and curing it by heating. The composite's combination of high strength and wear resistance makes it particularly suitable for applications requiring high loads and frequent reciprocating movements.
Advantages
1.Good wear resistance and long service life.
2.No metal contact on the sliding surface. 3.Control mechanical vibration. 4.Due to the effect of the wear-resistant ring, a larger radial clearance is allowed. 5.Simple groove design and strong load-bearing capacity. 6.Low maintenance cost.
