185x208x12mm Oil Seal | Brown NBR Nitrile Rubber Automotive Shaft Seal

This 185×208×12mm TC-type oil seal is a factory-direct aftermarket sealing solution designed for automotive rotating shaft systems, serving global distributors, professional repair workshops and fleet operators.

It adopts a fully rubber-covered steel skeleton structure with precision-machined primary sealing lip and secondary dust-proof lip, paired with a built-in high-carbon steel garter spring to maintain stable radial preload even under continuous shaft rotation and road vibration. It effectively retains gear oil, transmission fluid and bearing grease inside the shaft housing, and blocks external road dust, mud, grit and splash water from invading internal components to extend shaft and bearing service life.

We maintain sufficient finished goods inventory to support fast delivery and large-volume procurement, serving worldwide automotive aftermarket channels.
