CORTECO 19034983 Rotary Shaft Seal 32,5x57x9/17,9 ACM TB9Y

Applications - Engine and Automotive Rotary Seal

The CORTECO 19034983 32,5x57x9/17,9 ACM TB9Y is a precision-engineered rotary shaft seal designed for demanding automotive systems. This oil seal is commonly used as an engine seal or transmission shaft sealing ring, ensuring reliable oil retention in dynamic rotating assemblies.

With OEM reference Nissan 381898H500, this rotary oil seal is applied in selected Nissan models where dimensional accuracy and material performance are critical. It operates as a technical seal preventing lubricant leakage while protecting internal components from external contamination.

The 32,5x57x9/17,9 configuration ensures precise fitment in designated housings, making it suitable for professional workshops, fleet maintenance, and B2B automotive supply. Beyond automotive use, it may also serve in selected industrial applications requiring compact and reliable shaft sealing.

Advantages of ACM Material and TB9Y Design

Manufactured from ACM (acrylate rubber), this rotary shaft seal provides excellent resistance to oils and grease, as well as stable performance at elevated temperatures. Compared to standard NBR materials, ACM offers improved thermal stability in continuous engine operation.

The TB9Y construction features an advanced sealing profile, typically functioning as a double lip oil seal, enhancing contamination protection and extending service life. The additional lip helps prevent dust ingress while maintaining optimal oil retention.

Key performance benefits:

• Reliable rotary seal performance in dynamic systems

• High durability under continuous load

• Strong resistance to oils and grease

• Reduced risk of leakage in engine and drivetrain systems

• Precision fit for 32,5 mm shaft diameter

This makes it a dependable solution among hydraulic and automotive seals where consistent sealing efficiency is required.

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 ACM suitable for high temperature applications?
Yes. ACM offers good thermal stability and resistance to engine oils, making it suitable for automotive sealing systems.

How do I select the correct rotary shaft seal size?
Match the inner diameter to the shaft (32,5 mm), the outer diameter to the housing bore (57 mm), and verify the width 9/17,9 mm according to OEM specification.

Can this seal be used in industrial applications?
Yes, provided the operating conditions match the material and dimensional requirements. It is suitable for light industrial rotary sealing tasks.
