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 color can we receive under regular bulk order arrangement?
A: The standard finished color is deep blue. Customized color schemes can be confirmed for long-term stable bulk cooperation projects.

Q: Does this wear ring adopt split opening construction for installation?
A: Yes, it uses single straight split cut to facilitate convenient on-site assembly. Seamless integrated version can be customized upon special technical requirements.

Q: What core role does this piston seal ring play inside hydraulic cylinder assemblies?
A: It guides piston reciprocating movement, bears lateral dynamic load and avoids direct metal contact to reduce cylinder barrel abrasion.

Q: What working pressure environment fits modified PU wear ring?
A: It runs steadily under medium and medium-high pressure hydraulic systems. Glass filled PTFE performs better in continuous high-temperature and high-pressure scenarios.

Q: Can this component sustain stable operation during long repeated reciprocating cycles?
A: Definitely. Modified polyurethane has outstanding abrasion resistance and maintains stable tightness under continuous cyclic work.

Q: Can you supply separate individual pieces or complete hydraulic seal overhaul kits?
A: Single loose pieces are available for sales, and we can match different sealing accessories to assemble complete maintenance kits.

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.
