WR Wear Ring

The function of guide rings are to guide the shaft and hole sealing of a hydraulic cylinder, use as piston guide rings and rod wear ring absorbing transverse forces. At the same time, it prevents metal-to-metal contact, optimizing the performance of the sealing system.

WR wear ring seals have a rectangular cross-section with rounded or chamfered edges, thus preventing impermissible edge force in the corner radius of the grooves. The chamfers also serve to facilitate installation when inserting into the cylindrical tube or guide bush, for example.
