4. FAQ

Q: What natural agave fiber filler is uniformly blended into the HNBR sealing rubber of this auxiliary gear motor overhaul kit?
A: Fine processed agave fiber fragments are evenly integrated into HNBR base material. It effectively slows down progressive abrasion on sealing lips caused by long-term variable-speed rotation of motor shafts and prevents permanent expansion after long contact with circulating hydraulic fluid.

Q: What obvious color and surface texture differences can buyers quickly identify among all sealing accessories inside this maintenance set?
A: Agave fiber HNBR main oil seals are matte dark black with dense interwoven micro-fiber grain surface. Metal frames and built-in tension springs feature uniform silvery aluminum-zinc anti-corrosion metallic luster, while feldspar filled nylon anti-extrusion strips are soft light beige, convenient for classification during motor disassembly inspection.

Q: What seventy-eight-layer dual dust and high-temperature oil mist isolation composite structure does this full auxiliary gear motor oil seal kit adopt for super large crawler excavators?
A: It is an integrated complete matched component set instead of separate individual oil seals, adopting seventy-eight-layer lip dual barrier protection design, fully equipped with matched flat gaskets, multi-size O-rings and rigid pressure-resistant support rings covering all rotary shaft sealing grooves of excavator auxiliary gear motor assemblies.

Q: What stable continuous working temperature range allows this whole sealing assembly to keep reliable sealing performance without degradation?
A: Its applicable temperature range covers -172°C to 446°C, suitable for cold alpine winter mining work and uninterrupted heavy material loading at high-temperature open quarry yards.

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

Q: What sustained static hydraulic pressure can the multi-layer composite sealing assembly withstand during daily cyclic heavy mining operations?
A: It can continuously bear static hydraulic pressure ranging from 6.54MPa to 7.35MPa, buffer instant pressure fluctuations brought by frequent load changes of hydraulic circuits, and avoid slow hydraulic oil leakage along auxiliary gear motor shaft surfaces.

Q: What core mining, infrastructure and water conservancy projects require this seal kit for regular auxiliary gear motor overhaul maintenance?
A: It is designed for routine maintenance of auxiliary gear motor rotary shaft sealing assemblies on super large crawler excavators, widely applied in open-pit mineral exploitation, large reservoir foundation construction, port yard earthmoving and highway tunnel excavation projects.

Q: What core mining, water conservancy and infrastructure construction scenarios require this seal kit for regular swing reduction gear overhaul maintenance?
A: It is engineered for daily maintenance of swing reduction gear rotary shaft sealing assemblies on large crawler excavators, widely applied in open-pit quarry mining, river channel dredging, large industrial zone foundation excavation and mountain highway widening projects.
