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 notch design for installation?
A: Yes, it features multi-section split structure to facilitate quick assembly into piston grooves. Integrated non-split style can be customized on request.

Q: What main tasks does this piston guiding ring undertake?
A: It bears lateral force generated during piston reciprocation, prevents metal direct contact and reduces inner cylinder abrasion.

Q: What working pressure environment fits this cast polyamide wear ring?
A: It runs steadily under medium and medium-high pressure hydraulic systems. PTFE composite material performs better under continuous high pressure.

Q: Can this component sustain stable performance under frequent cyclic movement?
A: Absolutely. Reinforced cast polyamide delivers low friction coefficient and maintains reliable performance during long cycle operation.

Q: What hydraulic fluid can this guiding ring adapt to?
A: It matches conventional mineral hydraulic oil. PTFE series materials have wider compatibility with many synthetic hydraulic media.

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.
