5. FAQ

Q: What natural plant fiber filler is evenly mixed into the polyurethane piston seal of this tilt cylinder repair kit?
A: Processed short poplar fiber fragments are uniformly distributed into PU base material. It effectively restrains irreversible surface abrasion caused by long-term repeated piston stretching and retracting inside tilt cylinders and prevents permanent dimensional expansion after prolonged contact with high-pressure hydraulic transmission oil.

Q: What distinct color and surface texture differences can buyers quickly distinguish among four types of sealing accessories inside this maintenance package?
A: Poplar fiber PU piston seals are matte deep black with dense interwoven micro-fiber grain surface. Kaolin modified FKM rod seals are glossy solid black, wheat straw fiber NBR dust wipers are light taupe grey, and zinc oxide filled PTFE back-up rings are soft milky white, easy to classify during cylinder disassembly inspection.

Q: What multi-layer composite integrated sealing structure does this full cylinder seal kit adopt for heavy road grader tilt hydraulic cylinders?
A: It is an integrated full-spec matching component set instead of scattered single independent seals, including piston composite sealing group, rod pressure-resistant sealing lip, outer mud scraping dust wiper and inner anti-extrusion support rings, fully matching all sealing grooves of grader tilt hydraulic cylinders.

Q: What stable full operating temperature range can this complete cylinder sealing assembly maintain consistent reliable sealing efficiency?
A: Its applicable temperature range covers -168°C to 421°C, suitable for cold northern winter highway construction and continuous long-hour road surface trimming work under high-temperature open-air construction yards.

Q: Can this cylinder seal assembly be universally installed on hydraulic cylinders of all construction machinery models?
A: It is custom-sized and formula tailored exclusively for heavy road grader tilt cylinder piston and rod structures only, and cannot adapt to backhoe loader swing cylinders, small excavator bucket cylinders or heavy wheel loader lift cylinders of other equipment series.

Q: What maximum instantaneous hydraulic pressure can the multi-composite matched seal combination withstand without extrusion deformation damage?
A: This multi-layer matched sealing structure can resist instantaneous hydraulic pressure up to 7.72MPa, buffer sharp pressure surges generated by frequent tilt cylinder extension and retraction, and eliminate both internal and external hydraulic oil leakage inside cylinder cavities.

Q: What core municipal and highway construction scenarios require this cylinder seal kit for regular hydraulic cylinder overhaul maintenance?
A: It is designed for daily maintenance of tilt cylinder sealing assemblies on heavy road graders, widely applied in municipal road base reconstruction, highway pavement trimming, airport ground leveling and mountain village road widening projects.

Q: What core coastal logistics and large infrastructure construction scenarios require this seal kit for regular rear drive axle overhaul maintenance?
A: It is designed for daily maintenance of rear drive axle rotary shaft sealing assemblies on super heavy wheel loaders, widely applied in open-pit mineral stockpiling, seaport bulk container cargo transfer, highway aggregate yard operation and large industrial park ground backfilling projects.
