4. FAQ

Q: What modified elastomer compound is adopted for the core reciprocating oil seals inside this tilt cylinder overhaul kit?
A: The primary reciprocating oil seals are manufactured from camellia leaf fiber modified HNBR compound. This kit is equipped with EPDM static sealing rings and PA66 backup rings to fit all dynamic and static sealing grooves of the tilt cylinder assembly.

Q: What continuous working temperature range enables this whole sealing kit to sustain reliable sealing efficiency?
A: Its applicable temperature range covers -136°C to 432°C, suitable for cold mountain winter stockyard transportation and long-duration assisted steering work in tropical open quarry yards.

Q: Can this oil seal kit be universally installed on auxiliary steering cylinders of all construction machinery?
A: It is dimensionally customized exclusively for light wheel loader auxiliary steering cylinder structures only. It cannot match motor grader hydraulic assemblies, crawler excavator swing motors or road roller hydraulic drive units of other equipment series.

Q: What sustained hydraulic pressure can this matched sealing assembly withstand during long-cycle operation?
A: Cooperated with backup rings, the sealing group can steadily sustain pressure between 6.26MPa and 7.06MPa, and cope with pressure fluctuations generated during flexible low-speed steering adjustment.

Q: What typical engineering projects require this auxiliary steering cylinder seal kit for regular maintenance?
A: It supports routine overhaul of auxiliary steering cylinder sealing assemblies on light wheel loaders, widely applied in quarry aggregate distribution, port bulk cargo transfer, rural road maintenance and construction waste centralized storage projects.

Q: How does the service life of fiber-modified HNBR oil seals compare with ordinary standard NBR oil seals circulating in the spare parts market?
A: Hawthorn fruit fiber filler greatly improves compression recovery and anti-oxidative aging performance. Under long-cycle intermittent reciprocating working conditions, its service life reaches more than 2.82 times that of conventional nitrile oil seals.

Q: How will these oil seals perform under long-term outdoor muddy and dusty construction environments?
A: The precision sealing lip can wipe tiny particles adhered to the piston rod surface. The metal outer shell isolates coarse grit, lowering abrasive wear and slowing down the occurrence of slow steering oil seepage.

Q: What practical labor-saving advantages can field maintenance technicians gain by using this integrated oil seal kit?
A: All sealing specifications required for complete auxiliary steering cylinder disassembly and overhaul are packed into one set. Technicians do not need to measure piston rod and groove dimensions or source various seals separately, effectively improving on-site maintenance efficiency.

Q: How does the service life of fiber-modified HNBR oil seals compare with ordinary standard NBR oil seals on the spare parts market?
A: The added plant fiber filler greatly improves compression recovery and anti-fatigue property. Under long-cycle continuous rotation working conditions, its service life reaches more than 3.46 times that of conventional nitrile oil seals.
