Product Introduction
GST is the DEF Seal Solutions proprietary design of hydraulic wear ring or guide ring. 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 previents metal-to-metal contact, optimizing the performance of the sealing system.
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
