🔩 Oil Seal – TATA AL-3119, 63 mm (Serrated)
Product Type: Automotive Oil Seal
Part Code/Number: AL-3119
Application: Heavy-duty TATA commercial vehicles — models like LPT 3118, LPT 2518, LPT 3718, etc. (common fitment for rear axle/gearbox or engine sealing points)
Primary Function:
This 63 mm oil seal is engineered to prevent leakage of lubricating oil from rotating or reciprocating shafts in vehicle driveline assemblies. Its design provides a tight seal between the housing bore and the shaft to keep oil in and dirt/water out, which protects bearings and gears from contamination. Typical application is in differentials, transmission outputs, or axle housings on heavy-duty trucks such as Tata LPT series.
Key Features & Design Details:
Inner Diameter: ~63 mm – the dimension that fits around a shaft or spindle where sealing is required.
Serrated/“Serated” Lip:
Refers to a corrugated or textured sealing lip edge rather than a smooth one.
The serrations help the lip retain and distribute lubricant more effectively and improve sealing under dynamic conditions (vibration/shaft run-out).
It also aids in scraping away contaminants at the sealing surface.
Construction: Typically made of oil-resistant elastomer (e.g., NBR – nitrile rubber) bonded to a stamped metal carrier.
Elastomeric material ensures flexible sealing contact with the rotating shaft.
Metal reinforcement maintains shape and installation fit.
Beaded/Coil Spring: Many automotive seals include a garter spring inside the lip to ensure consistent radial pressure on the shaft for reliable leak prevention (common in many truck oil seals).
Seal Type: Radial lip seal — seals on a rotating shaft perpendicular to the axis.
Performance Benefits:
Prevents oil leakage from gearboxes, axles, and transmission housings.
Extends life of internal components (bearings, gears) by keeping contamination out.
Enhanced sealing thanks to serrated lip geometry for higher friction conditions.
Engineered for heavy-load and high-temperature truck environments
