4. FAQ

Q: How is its compatibility with gear oil and heavy‑duty lubricating grease?
A: The rubber material keeps stable performance under long‑term contact with gear oil and grease.

Q: Can these oil seals work well in sites full of sand and construction debris?
A: Auxiliary dust lip can block external grit, reducing abrasive damage to the main sealing lip.

Q: Are all items strictly manufactured to match standard shaft and housing dimensions?
A: Each oil seal is precision processed to fit standard shaft diameter and mounting bore size.

Q: Will the sealing lip suffer serious fatigue after long‑term continuous rotation?
A: Optimized rubber formula slows down fatigue deformation under long‑time rotating working status.

Q: Could this kit improve the lubricant leaking problem on shaft connection gaps?
A: Pre‑compressed lip design maintains proper contact pressure to reduce lubricant leakage risk.

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 6.34MPa and 7.14MPa, and buffer pressure fluctuations generated during sudden heavy digging impact.

Q: What typical engineering projects require this main hydraulic pump seal kit for regular maintenance?
A: It supports routine overhaul of main hydraulic pump sealing assemblies on medium excavators, widely applied in open pit mining, river dredging, urban foundation construction and highway expansion projects.

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.
