4. FAQ

Q: Can this piston seal ring adapt to hydraulic cylinders of all construction equipment?
A: It is specially matched for grader lift cylinders. It cannot be installed on excavator stick cylinders or wheel loader tilt cylinders.

Q: What color will we receive for regular bulk shipment?
A: Standard finished color is dark brown. Custom color schemes are negotiable when customers place long-term bulk orders.

Q: What color will we receive for standard bulk orders?
A: The regular finished color is dark grey brown. Customized colors can be discussed when customers place large volume long-term orders.

Q: Does this wear ring adopt segmented split design?
A: Yes, it features multi-section split notch design for convenient on-site installation. Integral seamless style can be customized according to special requirements.

Q: What main function does this piston guiding ring realize?
A: It bears lateral loads of piston assembly, isolates direct metal contact and reduces friction loss inside hydraulic cylinder assemblies.

Q: What working pressure environment fits this phenolic laminate guiding ring?
A: It works reliably under medium-high pressure with frequent impact loads. Bronze filled PTFE performs better under continuous ultra-high pressure conditions.

Q: Can this accessory maintain stable performance during long-term reciprocating cycles?
A: Absolutely. Woven fabric structure improves impact resistance and keeps low friction under repeated back-and-forth movement.

Q: Are these sealing rings sold separately or matched into overhaul kits?
A: Single-piece supply is available, and we can combine different sealing accessories to assemble complete hydraulic maintenance kits.

Q: What hydraulic fluid medium can this guiding ring adapt to?
A: It is compatible with conventional mineral hydraulic oil. PTFE composite materials have wider adaptability to multiple synthetic hydraulic fluids.

Q: Can you offer individual pieces or matched sealing repair kits?
A: Single-piece supply is available, and we can combine different sealing components into complete maintenance kits.

Q: What suggestions do you have for long-term storage of these plastic rings?
A: Keep them in cool and dry warehouse. Avoid high temperature environment and prolonged sunlight exposure. Different polymer materials should be stored separately.

Q: Are these goods sold separately or assembled into repair kits?
A: Single-piece supply is supported, and we can combine different sealing accessories into matched maintenance packages.

Q: What core function does this piston seal ring perform inside the cylinder?
A: It separates high-pressure and low-pressure oil chambers inside the cylinder and prevents hydraulic fluid from flowing across both sides of the piston.

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.
