CORTECO 19026224 Rotary Shaft Seal 65x82x7/13,5 NBR TB9Y

Applications - Wheel Hub and Automotive Shaft Seal

The CORTECO 19026224 65x82x7/13,5 NBR TB9Y is a precision rotary shaft seal designed for wheel hub and drivetrain systems. This oil seal functions as a shaft sealing ring that prevents lubricant leakage while protecting internal components against dirt and moisture.

Commonly used in automotive assemblies, it corresponds to OEM references including Ford 3669059, XM343N320AA and Mazda UC8633065A. The seal is engineered for dynamic rotary motion, ensuring stable performance in wheel hub systems where continuous rotation, vibration and load variations occur.

With its exact 65x82x7/13,5 mm dimensions, this rotary seal provides accurate fitment in designated housings. It is suitable for professional workshops, fleet service providers and B2B automotive supply chains, as well as selected industrial applications requiring reliable shaft sealing under moderate operating conditions.

Advantages of NBR Material and TB9Y Design

Manufactured from NBR (nitrile butadiene rubber), this oil seal offers excellent resistance to oils and grease, making it a widely used material in hydraulic and automotive seals. NBR provides stable elasticity and sealing efficiency in typical automotive temperature ranges.

The TB9Y profile incorporates an enhanced sealing geometry that functions similarly to a double lip oil seal, improving contamination protection and extending operational life. Compared to a single lip oil seal, this configuration offers increased reliability in environments exposed to dust and road debris.

Key performance features:

• Reliable rotary shaft seal performance in wheel hub assemblies

• High durability under continuous rotation

• Strong resistance to oils and grease

• Protection against dirt ingress and lubricant leakage

• Precise fit for 65 mm shaft diameter

This makes it a dependable technical seal for automotive drivetrains and selected industrial rotary applications.

FAQ - Frequently Asked Questions

What is the difference between single lip and double lip oil seals?
A single lip oil seal provides primary oil retention, while a double lip oil seal includes an additional dust lip for improved contamination protection and longer service life.

Is NBR suitable for oil and grease exposure?
Yes. NBR offers strong resistance to oils and grease and is commonly used in engine seals and automotive shaft sealing applications.

How do I select the correct rotary shaft seal size?
Match the inner diameter to the shaft (65 mm), the outer diameter to the housing bore (82 mm), and verify the width 7/13,5 mm according to the OEM specification.

Can this seal be used in industrial applications?
Yes, provided the operating conditions are within NBR material limits. It is suitable for light to medium-duty industrial rotary sealing tasks.
