CORTECO 19035124 Rotary Shaft Seal 35x54x9/21,8 ACM RHTC9Y

Application - Right-Hand Gearbox Output Shaft Seal

The CORTECO 19035124 35x54x9/21,8 ACM RHTC9Y is a precision rotary shaft seal designed for gearbox and drivetrain applications. This oil seal is commonly used as a shaft sealing ring for the right-hand gearbox output in selected Toyota models and compatible Suzuki vehicles.

The seal corresponds to OEM references:

• Suzuki 2743173H30

• Toyota 9031135057

• Toyota 9031135051

• Toyota 9031135043

With exact dimensions of 35x54x9/21,8 mm, the rotary seal ensures proper fitment and reliable oil retention in transmission systems exposed to continuous rotational load and elevated temperatures. The right-hand rotation design is critical for maintaining optimal sealing performance in directional shaft applications.

Advantages of BASL Construction and ACM Material

The BASL construction includes a metal insert, elastomer-coated outer diameter and an additional dust lip. In practice, it functions as a double lip oil seal, providing enhanced contamination protection and stable sealing under dynamic conditions.

Manufactured from ACM (acrylate rubber), the seal offers excellent resistance to oils and grease and improved thermal stability compared to standard NBR materials. ACM is particularly suitable for gearbox and drivetrain environments where long-term heat resistance is required.

Key performance benefits:

• Reliable rotary shaft seal for gearbox output shafts

• High durability under continuous operation

• Strong resistance to oils and grease

• Elastomer-coated outer surface for improved static sealing

• Precise fit for 35 mm shaft diameter

• Optimized for right-hand shaft rotation

Please note that the product may differ visually from illustrative images, which present general BASL construction and NBR material examples. The supplied version meets the RHTC9Y and ACM specification.

FAQ - Frequently Asked Questions

What is the difference between single lip and double lip oil seals?
A single lip oil seal retains lubricant on one side, while a double lip oil seal includes an additional dust lip for better contamination protection.

Does rotation direction matter for this seal?
Yes. This model is designed for right-hand rotation. Using the correct directional seal ensures optimal oil retention and longer service life.

Is ACM better than NBR for gearbox applications?
ACM provides improved thermal resistance and better long-term stability in high-temperature oil environments.

How do I select the correct shaft seal size?
Match the inner diameter to the shaft (35 mm), the outer diameter to the housing bore (54 mm), and confirm the width (9/21,8 mm) according to OEM specification.
