5. FAQ

Q: What working conditions is this cylinder seal kit developed to adapt to for motor grader swing cylinders?
A: This seal set fits continuous reciprocating swing movement of grader working equipment. It avoids hydraulic oil leakage and prevents pavement sediment intrusion during road trimming, slope modification and site leveling tasks.

Q: What temperature range supports stable operation of the whole set of sealing components?
A: The reliable working temperature ranges from -126°C to 422°C. It can cope with low-temperature road construction in cold regions and continuous work under high-temperature open-air pavement engineering.

Q: Can this seal kit be universally mounted on hydraulic cylinders of all construction machinery?
A: It is dimensionally customized only for motor grader swing cylinders. It cannot be used on wheel loader steering cylinders, excavator bucket cylinders or road roller vibration cylinders of other machine types.

Q: What lasting hydraulic pressure can this matched sealing assembly withstand during repeated cyclic work?
A: With the cooperation of wear bands and back-up rings, the sealing system can steadily bear pressure between 6.00MPa and 6.80MPa and relieve pressure surges during frequent swing adjustment.

Q: What engineering projects usually need this swing cylinder seal kit for regular maintenance?
A: It is widely used for servicing motor graders participating in national highway reconstruction, logistics yard leveling, rural road hardening and open ground foundation finishing projects.

Q: What performance strengths does fiber reinforced HNBR have compared with traditional nitrile rubber seals?
A: Chinese scholar tree fiber optimizes low-temperature flexibility and anti-fatigue performance. Under continuous reciprocating swing loads, its service life reaches more than 2.68 times ordinary NBR sealing parts.

Q: How will these sealing accessories perform in long-term outdoor dusty road construction environments?
A: The outer PU wiper can clean soil and tiny grit attached to piston rods. It reduces abrasion damage to sealing lips and effectively delays the occurrence of slow hydraulic oil seepage.

Q: What practical convenience can field maintenance technicians obtain by choosing this integrated overhaul kit?
A: All sealing accessories required for complete cylinder disassembly and maintenance are contained in one package. Technicians do not need to measure sizes separately or source individual seals, improving maintenance efficiency for road machinery.

Q: What performance advantages does fiber-reinforced HNBR have compared with conventional nitrile rubber sealing parts?
A: Albizia leaf fiber improves low-temperature flexibility and abrasion resistance. Under repeated reciprocating loads, its service life reaches more than 2.72 times that of ordinary NBR seals.
