4. FAQ

Q: Does this wear ring adopt split opening design?
A: Yes, it features single oblique split cut for convenient field assembly. Seamless integral type can be customized for special installation requirements.

Q: Where is this piston seal ring installed inside hydraulic cylinder?
A: It fits the outer piston groove and slides directly against the inner bore of hydraulic cylinder tube.

Q: What key performance does this seal deliver for grader working conditions?
A: It prevents hydraulic oil cross‑flow between piston chambers and maintains sealing performance under elevated oil temperature.

Q: Can this seal keep stable function under continuous variable pressure during road‑grading tasks?
A: Bronze‑filled formula improves heat conduction, the combined structure copes well with frequent pressure fluctuation.

Q: Are these piston seal rings produced with strict dimensional control?
A: Each sealing assembly is precision machined to fit standard piston groove dimensions for motor grader hydraulic cylinders.

Q: Will repeated piston reciprocating movement accelerate surface wear?
A: Bronze filler enhances wear resistance, slowing surface abrasion under long‑term cyclic piston strokes.

Q: Will long‑time cyclic piston movement produce heavy surface abrasion?
A: Modified polyamide formula lowers friction coefficient, slowing surface wear during continuous reciprocating strokes.

Q: Can this ring work independently without matching main piston sealing elements?
A: It acts as guiding and auxiliary sealing part; dedicated main piston seals are still required for full pressure holding.olding effect.

Q: What storage suggestions do you offer for these PTFE sealing accessories?
A: Keep goods in cool, dry warehouse. Avoid persistent high temperature and long-time ultraviolet radiation to slow material aging.

Q: What engineering projects commonly require replacement of this piston seal ring?
A: It serves routine maintenance of hydraulic cylinder piston sealing assemblies on medium crawler excavators, widely used in urban infrastructure, highway subgrade construction, small quarry loading and residential foundation excavation projects.
