Phenolic sandwich cloth guiding ring is composed of chemical fibre and epoxy resin, the product has long life, small friction resistance, good resilience, pressure resistance and water absorption resistance. In the hydraulic cylinder plays a supporting role, has a high workload capacity, support ring to avoid the dragging components of the metal material touch, with very good wear resistance and shock absorption efficacy. Can also be used as piston guiding components, applicable and accurate positioning of the piston in the cylinder barrel to carry out axial support points, the movement of accurate positioning.
Phenolic folder cloth guide ring isolation piston and cylinder cylinder, piston and guide sleeve of these two to the movement of the secondary parts, to avoid the movement of the secondary parts in the middle of the immediate cause of friction, damage and strain, very when the movement of the secondary parts of the steel parts, be sure to protect, otherwise it is very easy to strain.
Guide ring also has a key role is to reduce the movement between the sliding friction and friction work, reduce the failure of the work and heat, but also suitable for regulating the inner cavity, high negative load bearing capacity, to do before the ductility of the ductile temperature with ductility.
