185x210x22mm Rear Wheel Hub Oil Seal OEM DZ90129340063 | Brown NBR Heavy Duty Truck Shaft Seal

This 185×210×22mm TC-type rear wheel hub oil seal is a premium aftermarket replacement for heavy duty commercial truck rear wheel and drive shaft systems, matching OEM part number DZ90129340063.

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 heavy-load road vibration and impact. It effectively retains rear hub gear oil and bearing grease inside the assembly, and blocks road dust, mud, grit and splash water from invading the bearing chamber to extend wheel hub bearing service life.

We maintain sufficient finished goods inventory to support fast delivery and large-volume procurement, serving global truck parts distributors and aftermarket repair channels.
