CORTECO 19035127 Rotary Shaft Seal 23x37x7 ACM RHTC Oil Seal

Application - Gearbox Output Shaft Seal for Toyota

The CORTECO 19035127 23x37x7 ACM RHTC is a precision rotary shaft seal designed for transmission and drivetrain systems. Used as an oil seal and shaft sealing ring, it ensures reliable lubricant retention and contamination protection in dynamic automotive assemblies.

This model corresponds to OEM references:

• Toyota 90311W0001

• Toyota 9031123009

• Toyota 9031123008

It is commonly applied in selected Toyota gearbox systems, including compact vehicle platforms such as Toyota Aygo (application example). The 23x37x7 mm dimensions guarantee accurate housing fit and stable sealing performance under continuous rotational load.

The seal is designed for right-hand rotation, which is critical in directional shaft applications to maintain optimal oil retention.

Advantages of BASL Construction and ACM Material

The BASL construction features a metal reinforcement, elastomer-coated outer diameter and an additional dust lip. In practice, it functions as a double lip oil seal, providing improved protection against dirt and external contaminants while maintaining internal oil sealing.

Manufactured from ACM (acrylate rubber), this rotary seal offers enhanced resistance to oils and grease and improved thermal stability compared to standard NBR materials. ACM is particularly suitable for gearbox and drivetrain environments exposed to elevated temperatures and long-term oil contact.

Key benefits:

• Reliable rotary shaft seal for transmission systems

• High durability under continuous operation

• Excellent resistance to oils and grease

• Elastomer-coated outer surface for improved static sealing

• Precise fit for 23 mm shaft diameter

• Optimized for right-hand rotation

Please note that the product may visually differ from illustrative images showing general BASL construction and NBR material examples. The supplied version meets the RHTC 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 enhanced contamination protection.

Does rotation direction matter?
Yes. This seal is designed for right-hand rotation. Installing the correct directional seal ensures optimal performance and longer service life.

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

How do I select the correct shaft seal size?
Match the inner diameter to the shaft (23 mm), the outer diameter to the housing bore (37 mm), and confirm the width (7 mm) according to OEM specification.
