4. FAQ

Q: What four core raw materials form all sealing components inside this complete oil seal package?
A: The whole set is composed of oil-resistant NBR, carbon modified PTFE, heat-resistant ACM acrylic rubber and multi-layer laminated wear-resistant fabric for auxiliary dustproof parts.

Q: What inherent natural color does each category of sealing component retain without artificial pigment addition?
A: Regular NBR oil seals are solid matte black, carbon-filled PTFE sealing rings are deep charcoal grey, ACM rubber pieces are soft beige tan, laminated fabric dust guard rings are muted reddish brown.

Q: What core sealing function does NBR realize on various rotating shafts of wheel dozer?
A: Serving as primary shaft sealing material, NBR relies on good compression resilience to block gear oil and engine lubricant leakage while drive shafts and power shafts keep continuous rotary operation under variable load during ground pushing work.

Q: What is the core design purpose to equip carbon-filled PTFE as secondary auxiliary sealing layer together with NBR main lip seal?
A: It reduces rotational friction between seal inner lip and metal shaft surface and prevents NBR lip from rapid abrasion caused by tiny sand particles invading along shaft clearance in dusty construction surroundings.

Q: What obvious performance advantages does ACM acrylic rubber have compared with standard NBR rubber?
A: ACM stands out with superior high oil ageing resistance and heat stability, keeping stable sealing tightness when contacting high-temperature deteriorated gear oil inside axle housing after long-time continuous machine running.

Q: On which specific equipment positions are ACM rubber seals generally installed?
A: ACM seals are mainly arranged on high-temperature rotating positions such as transmission output shaft and rear axle hub where lubricating oil runs at relatively high working temperature.
