4. FAQ

Q: What core composite materials are used for the oil seals inside this steering pump overhaul kit?
A: The primary rotary oil seals adopt sophora leaf fiber modified HNBR material. The kit is equipped with FKM auxiliary sealing rings and rigid PA66 backup rings to fit all sealing positions of steering pump assembly.

Q: What visual differences help customers quickly identify different sealing accessories inside the package?
A: Fiber reinforced HNBR oil seals are jet black with smooth matte surface; metal shells and tension springs have uniform silvery anti-corrosion plating; nylon backup rings are light beige. All components have clean edges without burrs.

Q: What special working scenarios is this oil seal kit designed to adapt to on large wheel loader steering pumps?
A: This matched kit combines dynamic shaft lip seals and static flange sealing pieces. It avoids internal hydraulic oil leakage and prevents external sediment from invading the pump during frequent steering and material loading operations.

Q: What continuous working temperature range can this whole sealing kit maintain stable sealing capability?
A: Its applicable temperature range covers -172°C to 468°C, suitable for cold plateau winter stockyard operation and long-duration heavy aggregate handling work in tropical open mining sites.

Q: Can this oil seal kit be universally used for steering system overhaul 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 hydraulic motors or medium roller drive units of other equipment series.

Q: What sustained hydraulic pressure can this integrated sealing assembly withstand during long-term cyclic steering operation?
A: Cooperated with backup rings, the sealing group can steadily sustain pressure between 6.95MPa and 7.75MPa, and buffer pressure fluctuations generated during frequent steering startup and steering reversal.
