4. FAQ

Q: What natural banana fiber additive is evenly mixed into the HNBR sealing rubber of this bucket cylinder overhaul kit?
A: Ultra-fine crushed banana fiber filaments are uniformly incorporated into HNBR base material. It slows down surface fatigue abrasion caused by frequent extension and retraction of bucket cylinder rods and prevents permanent rubber expansion after long contact with high-pressure hydraulic oil.

Q: What obvious color and texture differences can customers easily identify among all sealing accessories inside this kit?
A: Banana fiber HNBR main seals are matte dark black with delicate interwoven micro-fiber texture. Alloy plated metal shells and tension springs show uniform silvery tin-zinc anti-corrosion luster, while diatomite filled nylon back-up rings are light off-white, convenient for sorting during cylinder disassembly.

Q: What seventy-three-layer dual dust and high-temperature oil mist barrier structure is adopted for this full bucket cylinder oil seal kit for large crawler excavators?
A: This is an integrated matched component set instead of separate single seals. It adopts seventy-three-layer lip double barrier design, equipped with matched gaskets, multi-size O-rings and pressure-resistant support rings suitable for all rod sealing grooves of excavator bucket cylinders.

Q: What working temperature range enables this complete sealing assembly to maintain stable sealing performance continuously?
A: Its applicable temperature range covers -175°C to 440°C, suitable for cold alpine region winter earthworks and continuous heavy grabbing work at high-temperature open-air mining yards.

Q: Can this oil seal kit be installed universally on hydraulic and drive systems of all construction machinery?
A: It is dimensionally and formula customized only for large crawler excavator bucket cylinder structures. It cannot be applied to road grader final drives, backhoe loader axles or medium wheel loader hydraulic cylinders of other machine models.

Q: What steady static hydraulic pressure can the multi-layer composite sealing assembly withstand during daily frequent grabbing and excavation work?
A: It can continuously withstand static hydraulic pressure ranging from 6.44MPa to 7.25MPa, ease sudden pressure fluctuations brought by frequent bucket impact, and avoid slow hydraulic oil leakage along the cylinder rod surface.
