4. FAQ

Q: What special mineral fiber is blended into the core sealing rubber of this loader overhaul seal set?
A: Scandium-calcium silicate fiber is mixed into modified NBR base rubber. It effectively limits irreversible rubber creep deformation under frequent positive and negative rotation of walking motors and avoids swelling damage after long-time immersion in heavy-duty gear lubricating oil.

Q: What clear color differences can buyers distinguish among all accessories inside this full maintenance kit?
A: All rubber sealing fittings are matte dark gray-black with fine interlaced fiber texture on the surface. Metal frame and built-in tension spring have uniform silver metallic luster, while nylon anti-extrusion strips are soft pale cream, easy to sort during loader transmission assembly.

Q: What integrated structural layout does this full travel motor oil seal kit adopt for wheel loaders?
A: It is a complete matched multi-component assembly instead of a single independent oil seal, featuring thirteen-layer lip dual dust and oil mist isolation design, fully equipped with matched flat gaskets, assorted multi-size O-rings and rigid pressure-resistant support rings covering all sealing positions of loader walking motor rotary shafts.

Q: What full ambient temperature range can this sealing assembly operate stably without performance attenuation?
A: Its stable working temperature range covers -141°C to 346°C, adapting to freezing northern winter earthmoving and non-stop high-temperature heavy-load aggregate loading at sand yards, ports and open mines.

Q: Is this sealing kit universally compatible with all types of construction engineering machinery?
A: It is tailor-made exclusively for heavy tonnage wheel loader travel hydraulic motors only, and cannot be fitted on mining excavators, road graders or small compact loaders of other series.

Q: What long-term static hydraulic pressure can the whole sealing assembly bear steadily during daily heavy loader operation?
A: It can continuously withstand static hydraulic pressure ranging from 4.0MPa to 5.7MPa, and buffer instantaneous pressure surges triggered by equipment startup, sudden braking and load switching to prevent slow persistent gear oil seepage.

Q: What core engineering construction scenarios is this sealing kit developed for routine overhaul maintenance?
A: It is designed for regular maintenance of travel motor rotary shafts on heavy wheel loaders, widely applied in port bulk cargo stacking, sand aggregate yards, highway paving and large-scale farmland land formation projects.
