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: Does this wear ring adopt split notch structure for assembly?
A: Yes, it uses stepped split cut for convenient on-site installation. Seamless integrated style can be customized according to special technical demands.

Q: What core function does this piston seal ring perform in hydraulic cylinders?
A: It bears lateral load during piston reciprocation, prevents direct metal contact and reduces friction abrasion of cylinder inner wall.

Q: What working pressure range fits fabric phenolic resin guiding ring?
A: It operates reliably under medium-high pressure with frequent impact loads. Graphite filled PTFE works better under continuous ultra-high pressure conditions.

Q: Can this accessory maintain stable performance under long cyclic reciprocating movement?
A: Definitely. Woven fabric structure enhances impact resistance and retains low friction during repeated back-and-forth operation.

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.
