4. FAQ

Q: What main function does this piston guiding ring achieve?
A: It supports piston assembly, bears lateral force and avoids metal friction to protect hydraulic cylinder inner wall.

Q: What pressure condition fits bronze filled PTFE guiding ring?
A: It runs reliably under continuous high pressure environment. Fabric laminated plastic works better under frequent impact load.

Q: Can this accessory keep stable performance during repeated reciprocating movement?
A: Absolutely. Bronze filler enhances self-lubricating characteristic and reduces abrasion in long cycle operation.

Q: Can you supply separate pieces or complete hydraulic seal maintenance kits?
A: Single-piece supply is available, and we can match different sealing spare parts into full overhaul kits.

Q: What hydraulic fluid medium can this guiding ring adapt to?
A: It matches mineral hydraulic oil and multiple synthetic hydraulic fluids, with excellent chemical stability.

Q: What working pressure range fits phenolic resin wear rings?
A: It runs steadily under medium-high pressure with frequent impact loads. Carbon filled PTFE suits continuous ultra-high pressure working environments.

Q: Can this component maintain stable performance under long reciprocating cycles?
A: Absolutely. Internal fiber reinforcement enhances shock resistance and keeps low friction during repeated cyclic movement.

Q: Can you offer separate single pieces or matched hydraulic seal overhaul kits?
A: Single-piece supply is available, and we can combine different sealing spare parts into complete maintenance packages.

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.
