WEAR-RING IMPORTED QUALITY

The guide ring or wear ring guides a hydraulic cylinder piston and rod and absorbs lateral forces. Metal to metal contact between the moving parts of the cylinder, for instance between the piston and the cylinder or the rod and the cylinder head. The advantages of these non-metallic guide rings (compared with traditional metal guide rings) are, among others, a high bearing load capacity, the elimination of local stress concentrations, wear resistance, a low coefficient of friction and low maintenance costs.  

Advantages 

1. The tapes can be supplied either cut to length or by the meter, to be cut according to requirement.
2. High load capacity (compressive strength), low wear and reduced friction due to an additive of carbon to the PTFE material.
3. No tendency to stick-slip in the case of low sliding speed.
4. Available in practical dimensions.
5. Simple groove designs.
6. Simple piston designs without metallic contact of the sliding surfaces.
7. Profile geometry which is exactly suited to work in lubricated air as well as dry and oil-free air.
