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 color can customers get for regular bulk shipment?
A: The standard finished color is off-white. Customized color options can be confirmed for stable large-volume orders.

Q: Does this wear ring adopt split opening design?
A: Yes, it adopts oblique single split cut for convenient field assembly. Integral seamless style can be customized according to special requirements.

Q: What core function does this piston seal ring undertake?
A: It bears lateral loads during piston reciprocating movement and avoids direct metal contact to reduce internal abrasion of hydraulic cylinders.

Q: What working pressure range fits glass fiber filled POM wear rings?
A: It runs reliably under medium pressure hydraulic systems. Bronze filled PTFE performs better under long-term continuous high pressure.

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.
