🔧 Tata Truck Oil Seal (Serrated) — For LPK 3118 / LPK 2523 / 3718 / 3723
Part Description:
A serrated oil seal designed for heavy-duty Tata truck applications — specifically models such as LPK 3118, LPK 2523, 3718, 3723. This component is used to seal rotating shafts and housings in gearboxes, axles, transfer cases, or differential units to prevent oil leakage and keep contaminants out.
📌 Key Features
✔ Serrated Seal Lip
The seal’s inner lip has a serrated (corrugated) edge rather than a smooth edge.
Serrations help:
Maintain a better lubricant film at the sealing surface.
Improve contaminant wiping (dirt, grit) during shaft rotation.
Enhance the seal’s performance in vibration and high-rpm conditions common in commercial vehicles.
✔ Material Construction
High-quality elastomer (rubber) — oil-resistant, heat-resistant compound (commonly Nitrile, HNBR, or similar automotive grade).
Reinforced metal case — provides structural support and accurate fit in the housing bore.
Often includes a garter spring on the inner lip for consistent radial pressure against the shaft.
✔ Function & Purpose
Creates a tight barrier between the rotating shaft and stationary housing.
Prevents gear oil leakage from differentials, axles, or gearbox assemblies.
Stops external contaminants (dust, water, debris) from entering the lubrication system.
Extends life of bearings, gears, shafts by preserving proper lubrication.
