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 orders?
A: The standard finished color is ivory off-white. Customized color options can be arranged for stable large-volume long-term cooperation.

Q: Does this wear ring adopt split opening construction?
A: Yes, it features straight oblique split notch for convenient on-site installation. Integral seamless type can be customized upon special technical requirements.

Q: What key function does this piston seal ring undertake inside hydraulic cylinders?
A: It bears lateral force generated during piston reciprocation, avoids direct metal contact and protects cylinder inner wall from friction damage.

Q: What working pressure range fits cast nylon guiding ring?
A: It works steadily under medium and medium-high pressure environments. Carbon filled PTFE performs better under continuous heavy high pressure.

Q: Can this component keep stable performance under long cyclic reciprocating movement?
A: Absolutely. Cast nylon features balanced rigidity and wear resistance, maintaining reliable operation under repeated working cycles.

Q: Can you provide separate single pieces or matched hydraulic seal overhaul kits?
A: Loose single-piece supply is available, and we can assemble various matching sealing spare parts into complete maintenance kits.

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.
