CORTECO 19034985 Rotary Shaft Seal 44x60x8 ACM LHTBY

Applications - Transmission and Drivetrain Shaft Seal

The CORTECO 19034985 44x60x8 ACM LHTBY is a precision rotary shaft seal engineered for demanding automotive systems. Designed as a reliable oil seal and shaft sealing ring, it prevents lubricant leakage while protecting internal components from contamination in dynamic rotating assemblies.

This rotary oil seal corresponds to OEM number Nissan 32136CD000 and Infiniti 32136CD000, ensuring compatibility with selected transmission and drivetrain applications. With dimensions 44x60x8 mm, it provides accurate fitment in designated housings and supports stable performance in gearboxes and drive units where the shaft rotates without a predefined direction.

Thanks to its robust design, the seal is suitable for professional automotive workshops, fleet maintenance, and B2B distribution, as well as selected industrial applications requiring reliable rotary sealing.

Advantages of ACM Material and LHTBY Design

Manufactured from ACM (acrylate rubber), this rotary shaft seal offers strong resistance to oils and grease and maintains elasticity at elevated operating temperatures. Compared to standard NBR materials, ACM performs better in high temperature environments typical of modern engines and transmissions.

The LHTBY design defines a reinforced sealing profile with optimized lip geometry. In practice, it functions similarly to a double lip oil seal, improving contamination protection and extending service life under dynamic conditions. Unlike a basic single lip oil seal, this construction enhances operational stability and sealing efficiency.

Key benefits include:

• Reliable rotary seal performance in continuous operation

• High durability under variable load and temperature

• Strong resistance to oils and grease

• Bidirectional operation without defined rotation direction

• Precise fit for 44 mm shaft diameter

This makes it a dependable solution within hydraulic and automotive seals where consistent technical sealing 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 to improve contamination protection and extend service life.

Is ACM suitable for high temperature applications?
Yes. ACM provides improved thermal stability and resistance to lubricants, making it suitable for engine and transmission environments.

How do I select the correct rotary shaft seal size?
Match the inner diameter to the shaft (44 mm), the outer diameter to the housing bore (60 mm), and confirm the width (8 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.
