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 opening design?
A: Yes, it features diagonal split cut for convenient field installation. Integrated non-split style can be customized on request.

Q: What is the primary function of this piston guiding ring?
A: It supports piston components, absorbs lateral force and avoids direct metal friction to protect hydraulic cylinder assemblies.

Q: What working pressure can phenolic resin wear rings withstand?
A: It works reliably under medium-high pressure conditions. Carbon-filled PTFE material performs better under continuous ultra-high pressure.

Q: Can this product sustain stable performance under frequent reciprocating motion?
A: Absolutely. The fabric reinforcement improves wear resistance and keeps steady during long-time repeated movement.

Q: Are these sealing rings sold separately or assembled into repair kits?
A: Single-piece supply is available, and we can combine various matching sealing accessories into complete service 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.
