4. FAQ

Q: What modified elastomer raw material is adopted for the core rotary oil seals inside this steering pump overhaul kit?
A: The primary rotary oil seals adopt sycamore twig fiber modified HNBR compound. This kit is equipped with FKM static sealing rings and PA66 backup rings to fit all dynamic and static sealing grooves of the steering pump assembly.

Q: What visual characteristics help buyers quickly distinguish all sealing accessories inside the package?
A: Fiber reinforced HNBR oil seals are matte deep black with subtle uniform grain; metal shells and tension springs have consistent silvery manganese silicate passivated surface; nylon backup rings are light cream. All accessories are precision trimmed without burrs or surface warpage.

Q: What frequent intermittent rotation working conditions is this oil seal kit designed to adapt to on large wheel loader steering pumps?
A: This integrated kit combines rotary shaft lip seals and static flange sealing assemblies. It prevents steering hydraulic medium leakage and blocks external muddy pollutants from entering the pump during continuous direction adjustment and bulk material loading operations.

Q: What continuous working temperature range enables this whole sealing kit to sustain reliable sealing capacity?
A: Its applicable temperature range covers -152°C to 448°C, suitable for cold highland open-pit mining transportation and long-duration frequent steering work in tropical open quarry yards.

Q: Can this oil seal kit be universally installed on steering pumps of all construction machinery?
A: It is dimensionally customized exclusively for large wheel loader steering pump 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 6.66MPa and 7.46MPa, and cope with pressure fluctuations generated during continuous left and right steering switching.

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: Bamboo leaf fiber filler greatly improves compression recovery and anti-wear stability. Under long-cycle variable-speed rotation working conditions, its service life reaches more than 2.78 times that of conventional nitrile oil seals.

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.
