70x132x12/30 mm TA‑Type Differential Pinion Oil Seal, Heavy‑Duty Axle Shaft Seal

This 70x132x12/30 mm TA‑type stepped‑shell pinion oil seal is heavy‑duty sealing component for heavy‑truck differential pinion shaft / axle shaft applications.

Stepped two‑tone painted metal outer shell provides firm press‑fit inside differential housing. Double‑lip with garter spring maintains consistent lip pressure on rotating shaft. It keeps gear oil inside differential housing, and prevents mud, splash‑water, road dust entering axle assembly, protects bearings and gear set from contamination damage.

Aftermarket heavy‑duty replacement part, widely used for commercial trucks, heavy‑duty logistics vehicles. Suitable for auto‑parts wholesalers, repair workshops and overseas bulk procurement.

Core functions

• Gear‑oil retention: Prevent differential gear‑oil leakage
• Mud & water exclusion: Resist splash‑water, mud and road‑grit ingress
• Stepped metal shell: Anti‑deformation during press‑fit installation
• Garter‑spring pre‑load: Stable sealing pressure under vibration and medium pressure

Features & Benefits

• TA‑type stepped two‑tone painted metal shell, anti‑deformation for heavy‑truck differential pinion installation.

• NBR double‑lip plus garter‑spring pre‑load design, holds gear‑oil and blocks mud, splash‑water and road contaminants simultaneously.

• Strict dimensional tolerance control, high‑quality aftermarket heavy‑duty truck replacement sealing part.

• Standard dimension for differential housing, convenient repair installation without mechanical modification.

• OEM private‑label service available, custom logo printing and export‑special packaging for overseas brand‑owner clients.

• Precision vulcanization craft, firm bonding between rubber lip and metal shell, good anti‑vibration performance for vehicle drivetrain.

• FKM fluoro‑rubber upgrade option available for severe high‑temperature working conditions.

Material & Process

• Material：NBR nitrile rubber sealing lip, painted carbon‑steel stepped metal shell, stainless steel garter spring
