145x175x27mm NBR Combination Rear Wheel Oil Seal, Oil‑Resistant Wear‑Resistant Truck Sealing Part

This combination rear wheel oil seal size 145×175×27 mm is high‑quality aftermarket replacement part for heavy‑duty commercial truck rear axle hub.

Adopts integrated composite sealing structure with NBR rubber sealing lip and built‑in garter spring. Effectively retains rear axle gear oil inside hub assembly, avoids lubricant leakage under heavy‑load road vibration. The outer dust‑proof structure blocks road mud, sand, dust and splash‑water from invading wheel‑hub bearing chamber. Widely used for truck repair workshops, domestic auto‑parts wholesale and cross‑border commercial‑vehicle‑parts export business.
