CORTECO 19034986 Rotary Shaft Seal 59x80x12 ACM RHTB9Y

Applications - Transmission and Drivetrain Shaft Seal

The CORTECO 19034986 59x80x12 ACM RHTB9Y is a precision rotary shaft seal designed for demanding automotive and selected industrial applications. This oil seal functions as a shaft sealing ring that ensures effective lubricant retention while preventing the ingress of dust and contaminants in dynamic rotating systems.

It corresponds to OEM number Nissan 331424N200 and is used in selected drivetrain and transmission assemblies. With its exact 59x80x12 mm dimensions, the seal guarantees accurate fitment in designated housings, supporting stable and long-term operation in gearboxes and other rotary units.

Thanks to its bidirectional design without a specified rotation direction, this rotary seal can operate reliably regardless of shaft movement orientation, simplifying installation and reducing the risk of incorrect mounting.

Advantages of ACM Material and RHTB9Y Design

Manufactured from ACM (acrylate rubber), this rotary shaft seal provides strong resistance to oils and grease, as well as stable performance at elevated operating temperatures. Compared to standard NBR materials, ACM is better suited for modern transmission and engine environments where thermal stability is essential.

The RHTB9Y construction defines a reinforced sealing profile with optimized lip geometry. In practical terms, it performs similarly to a double lip oil seal, offering enhanced contamination protection and improved service life under continuous dynamic load.

Key performance characteristics:

• Reliable rotary oil seal performance

• High durability in continuous operation

• Strong resistance to oils and grease

• Stable sealing without defined rotation direction

• Precise fit for 59 mm shaft diameter

This makes it a dependable technical seal within hydraulic and automotive seals, where consistent sealing efficiency and dimensional accuracy are critical.

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 transmission applications?
Yes. ACM offers good resistance to oils and elevated temperatures, making it suitable for drivetrain and gearbox sealing systems.

How do I select the correct shaft seal size?
Match the inner diameter to the shaft (59 mm), the outer diameter to the housing bore (80 mm), and confirm the width (12 mm) according to OEM specification.

Can this seal be used in industrial applications?
Yes, provided operating conditions are within ACM material limits. It is suitable for selected industrial rotary sealing tasks.
