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 adopt split cutting design?
A: Yes, it uses oblique split design to simplify on-site installation. Integrated non-split design can be produced upon special requests.

Q: What core function does this piston guiding ring perform?
A: It guides piston movement and prevents direct metal contact to reduce abrasion inside hydraulic cylinder assemblies.

Q: What pressure environment is suitable for this carbon-filled PTFE product?
A: It runs smoothly under continuous high-pressure conditions. Modified nylon material is more cost-effective for medium-pressure working scenarios.

Q: Can the product keep stable performance under frequent reciprocating motion?
A: Definitely. Carbon filler enhances self-lubricating property and lowers wear during long-term repeated movement.

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.
