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: What two main functions can this component achieve?
A: It guides piston reciprocating motion, avoids metal contact, and assists to reduce cross‑chamber hydraulic oil leakage.

Q: Can this ring handle side thrust generated by bucket lifting and dumping work?
A: The fabric‑reinforced structure can bear moderate radial side load and keep stable sliding under variable working load.

Q: Are these piston seal rings processed with strict dimensional control?
A: Every ring is precision machined to satisfy standard piston groove dimension for wheel loader hydraulic assemblies.

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.
