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: Does this wear ring feature split opening design?
A: Yes, it uses inclined single split cut for convenient field assembly. Seamless integrated type can be manufactured upon personalized requests.

Q: What core role does this piston seal ring play in hydraulic cylinders?
A: It supports piston assembly, bears transverse force and prevents metal-to-metal friction to reduce cylinder internal wear.

Q: What working pressure range suits modified POM wear rings?
A: It operates steadily under medium pressure hydraulic systems. Bronze filled PTFE is more suitable for continuous high-pressure working environments.

Q: Can this component maintain stable performance under frequent reciprocating cycles?
A: Absolutely. Modified POM possesses low friction coefficient and keeps consistent performance under long-time repeated movement.

Q: Can you supply separate single pieces or full hydraulic seal maintenance kits?
A: Single-piece supply is available, and we can match various sealing accessories to assemble complete overhaul kits.

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.
