5. FAQ

Q: What modified elastomer material is adopted for the core reciprocating oil seals inside this side shift cylinder overhaul kit?
A: The primary reciprocating oil seals adopt cedar leaf stalk fiber reinforced HNBR compound. This kit is equipped with NBR static sealing rings and PA66 backup rings to fit all dynamic and static sealing grooves of the side shift cylinder assembly.

Q: What intermittent reciprocating working conditions is this oil seal kit designed to adapt to on HG100 motor grader side shift cylinders?
A: This integrated kit combines piston reciprocating seals and static flange sealing pieces. It prevents hydraulic oil leakage and blocks external muddy pollutants from entering the cylinder during frequent lateral blade shifting and road leveling operations.

Q: What continuous working temperature range enables this whole sealing kit to sustain reliable sealing capacity?
A: Its applicable temperature range covers -129°C to 425°C, suitable for cold mountain winter road maintenance and long-duration blade lateral adjustment work in tropical open construction yards.

Q: Can this oil seal kit be universally installed on side shift cylinders of all construction machinery?
A: It is dimensionally customized exclusively for HG100 motor grader side shift cylinder structures only. It cannot match wheel loader 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 6.08MPa and 6.88MPa, and cope with pressure fluctuations generated during rapid side shift of the grading blade.

Q: What typical engineering projects require this side shift cylinder seal kit for regular overhaul?
A: It supports routine overhaul of side shift cylinder sealing assemblies on motor graders, widely applied in highway surface trimming, airport pavement construction, rural road upgrading and mine access road finishing 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: Cedar leaf stalk fiber filler greatly improves compression recovery and anti-hydrolysis aging performance. Under long-cycle intermittent reciprocating working conditions, its service life reaches more than 2.70 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 adhered to the piston rod surface. The metal outer shell isolates coarse grit, lowering abrasive wear and slowing down the occurrence of slow steering oil seepage.

Q: How well can this full sealing kit block mud, gravel dust and hot gear oil mist on muddy outdoor road job sites?
A: The multi-layer flexible rubber lip scrapes thick mud off the shaft surface, the fully enclosed plated metal shell blocks coarse dust particles, and inner auxiliary rubber layers isolate high-temperature oil mist to protect internal precision gears.
