5. FAQ

Q: What structural design is adopted for this oil seal kit suitable for bulldozers?
A: It adopts double-lip sealing plus integrated dustproof structure, matched with complete auxiliary gaskets and support rings. It is an integrated maintenance combination set, specially designed for bulldozer travel motor shaft sealing.

Q: What working temperature environment can this bulldozer seal kit adapt to?
A: It can work stably at -120°C to 335°C, adapting to low-temperature freezing construction in northern areas and continuous high-temperature operation of bulldozer walking system under long-load working conditions.

Q: Is this oil seal kit universal for all engineering machinery?
A: It is professionally customized for crawler bulldozer travel motor systems only, with exclusive size and structure, not suitable for excavators, loaders or other types of construction machinery.

Q: What working pressure can this sealing assembly bear during bulldozer operation?
A: It can stably bear long-term mechanical pressure of 3.5MPa–5.2MPa, and effectively buffer instantaneous pressure impact generated by bulldozer walking start and stop, avoiding oil leakage failure.

Q: What working scenarios is this bulldozer oil seal kit mainly applicable to?
A: It is suitable for daily maintenance and overhaul of travel motor shafts of large crawler bulldozers, widely used in open-pit mining, road leveling, earthwork filling and harsh field construction scenarios.

Q: What is the service life performance of this modified composite seal compared with ordinary seals?
A: The upgraded composite formula enhances anti-aging and anti-fatigue performance. Under standard field construction conditions, its overall service life is about 1.6 times longer than that of ordinary single-structure oil seals.

Q: How is the dustproof and anti-fouling performance of this product in harsh field environments?
A: The double-lip dustproof structure can effectively block a large amount of field silt, gravel dust and floating oil dirt, prevent foreign matter from entering the travel motor, and protect internal precision transmission parts.

Q: What are the practical advantages of adopting this full set of matching seal accessories for maintenance?
A: All accessories are completely matched according to original equipment standards with full specifications. One set can complete the overall sealing replacement of the travel motor, which simplifies maintenance steps and improves on-site repair efficiency.
