154x175x24mm Rear Wheel Axle Oil Seal | Brown NBR

This 154x175x24mm TC-type rear wheel axle oil seal is a premium aftermarket replacement part designed for heavy-duty commercial truck rear axle hub systems.

Adopts fully rubber-covered skeleton structure with precision-machined sealing lip and built-in garter spring, delivers stable radial preload for long-term sealing. Effectively retains rear axle gear oil inside hub assembly, prevents lubricant leakage under heavy-load road vibration and harsh working conditions. The outer dust-proof rib structure blocks road mud, sand, dust and splash-water from invading wheel hub bearing chamber, extends bearing service life.

Widely adopted in truck repair workshops, auto parts distributors and cross-border aftermarket sealing parts business, compatible with most heavy-duty truck rear axle models in global markets.
