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.
Material
Popular wear ring materials include glass filled Nylon, bronze filled PTFE,
glass filled PTFE, Phenolic and PEEK.
Type of cut
Wear rings are available in butt cut, angle cut and step cut styles.
Function
1. Good dimensional stability, can absorb stock
2. Uniform distribution of the large radial force
3. Low coefficient of friction, good sliding performance
4. Higher load bearing capacity
5. Excellent wear resistance
6. Wipe effect
7. Easy to install
8. Long service life
Medium: Mineral oil based hydraulic fluids, barely flammable hydraulic fluids,
water, air and others.
