4. FAQ

Q: What reinforced elastomer formulation is adopted for the core rotary oil seals inside this auxiliary steering pump overhaul kit?
A: The primary rotary oil seals are manufactured from hawthorn leaf fiber modified HNBR compound. This kit contains NBR static sealing rings and PA66 backup rings to fit all dynamic and static sealing grooves of the auxiliary steering pump assembly.

Q: What exterior characteristics help buyers quickly distinguish all sealing accessories inside the package?
A: Fiber reinforced HNBR oil seals are matte jet black with subtle uniform texture; metal shells and tension springs have smooth silvery zirconium passivated coating; nylon backup rings are light ivory. All accessories are precisely trimmed without burrs or surface warpage.

Q: What variable load operating conditions is this oil seal kit designed to cope with on medium large wheel loader auxiliary steering pumps?
A: This integrated kit combines rotary shaft lip seals and static flange sealing pieces. It stops hydraulic oil leakage and prevents external contaminants from entering the pump during low-speed steering and material stacking operations.

Q: What continuous working temperature range allows this whole sealing kit to maintain stable sealing performance?
A: Its applicable temperature range covers -154°C to 450°C, suitable for cold plateau winter stockyard transportation and long-duration frequent steering work in tropical open quarry yards.

Q: Can this oil seal kit be universally installed on auxiliary steering pumps of all construction machinery?
A: It is dimensionally customized exclusively for medium large wheel loader auxiliary steering pump structures only. It cannot match motor grader hydraulic assemblies, crawler excavator swing motors or medium 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 6.62MPa and 7.42MPa, and cope with pressure fluctuations generated during low-speed steering and load shifting.

Q: What typical engineering projects require this auxiliary steering pump seal kit for regular overhaul?
A: It supports routine maintenance of auxiliary steering pump sealing assemblies on medium large wheel loaders, widely applied in quarry aggregate storage, port bulk cargo transfer, rural road upgrading and construction waste landfill 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 leaf fiber filler significantly improves compression recovery and anti-medium aging performance. Under long-cycle intermittent rotation working conditions, its service life reaches more than 3.18 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 attached to the rotating shaft surface. The metal outer shell isolates coarse grit, lowering abrasive wear and slowing down the occurrence of slow hydraulic oil seepage.

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.
