150x180x15/16mm TC Type NBR Oil Seal | for Heavy Duty Truck Axle Hub

This 150×180×15/16mm TC-type oil seal is a cost-effective aftermarket replacement solution designed for B2B buyers including auto parts distributors, fleet operators and repair workshops.

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

Widely used in heavy duty trucks, commercial buses, construction machinery and industrial equipment chassis sealing systems. Suitable for bulk sourcing, aftermarket distribution and cross-border trade.
