Phenolic cloth clamping guide ring is composed of chemical fiber and epoxy resin. The product has long service life, low friction, good resilience, compression resistance and water absorption resistance. It plays a supporting role in the hydraulic cylinder and has high load working capacity. The support ring avoids the touch of metal materials of drag components, and has very good wear resistance and shock absorption effect. It can also be used as a piston guide component, which is suitable for and accurate positioning. It can accurately locate the axial support point of the piston in the cylinder barrel.

The phenolic cloth clamping guide ring separates the piston and cylinder barrel. The piston and guide sleeve can immediately scratch, damage the ring and strain the moving auxiliary parts and avoid the middle of the moving auxiliary parts. When the moving auxiliary parts are all steel parts, be sure to protect them, otherwise they are very easy to strain.

Another key function of the guide ring is to reduce the sliding friction and friction work between movements, reduce the failure work and heat, and is also suitable to standardize the inner cavity, high negative bearing capacity and ductility before reaching the ductility temperature.
