PTFE Wear Strips

Pioneer Trading Corporation offers PTFE Wear Strips. It is used as a guide for metallic pistons and rods in hydraulic and pneumatic cylinders. Properties: high load bearing capabilities; break away and dynamic friction are low (µ = 0,5); no stick-slip, even when operating under heavy loads and low linear velocities; self lubricating, sliding metallic interfaces do not make contact; therefore, materials for piston, cylinder rod and rod guide may be selected from a wide range of materials; more play between diameters is permissible; in a dirty environment, the wiper action of the wear strip will catch contaminants on the top surface and therefore prevent damage to sealing and contact areas; if the wear strips are correctly designed and installed, there is no danger of hydrodynamic pressure build-up at the wear strips; this obviates expensive machining of spiral flutes or drilling longitudinal holes to relieve drag pressure; and pressure waves caused by shock loads and vibrations are damped by the wear strips before reaching the sealing area; this reduces the danger of seal destruction. The thickness, width and length of the tape bearing can be made-up to suit a given application.
