5. FAQ

Q: What unique reinforcing filler is added to the main sealing lip material, and what core benefit does it bring?
A: Vanadium-silicate fiber is blended into modified NBR. It effectively slows rubber creep deformation under long high-speed rotation and avoids swelling failure after long contact with high-pressure hydraulic oil.

Q: What distinct color features do all internal accessories have for easy identification?
A: All rubber sealing pieces are matte charcoal black with fine interwoven fiber texture. Metal skeleton and spring are bright silver. Nylon anti-extrusion strips are light beige, with obvious color distinction during assembly sorting.

Q: What overall structural style does this overhaul seal set adopt?
A: It is a full matched multi-piece combination style instead of single independent oil seal. It adopts eight-lip layered dust blocking design, equipped with all matching gaskets, O-rings and rigid back-up rings for full pump shaft overhaul.

Q: What full range of ambient temperatures can this seal assembly adapt to?
A: Stable working range from -142°C to 352°C, adapting to frigid alpine mining winters and continuous high-temperature full-load operation in tropical open-pit mines.

Q: Is this seal set universal for various construction machinery models?
A: It is exclusively customized for super-large tonnage mining excavator main hydraulic pumps only. It cannot be applied to loaders, road graders or medium and small excavators.

Q: What long-term static hydraulic pressure can this whole set withstand steadily?
A: It can continuously bear static hydraulic pressure of 4.25–6.0MPa, and buffer instantaneous pressure surges generated during equipment startup and heavy load switching to prevent oil seepage.
