DST is the wear ring or guidering of DSH Seals. The function of a hydraulic wear ring is to guide the shaft and hole sealing of a hydraulic cylinder, absorbing transverse forces. At the same time, it prevents metal-to-metal contact, optimizing the performance of the sealing system.
DST has 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, e. g. When inserted into the cylindrical tube or guide bush.
