Applications & Technical Specifications

Advantages & Design Features

Description

The Rotary Shaft Seal CORTECO 19027779 NBR TC9Y is a premium oil seal / shaft seal engineered for differential and other rotating shaft applications. With dimensions of 40 mm (ID) x 72 mm (OD) x 11/18.5 mm (thickness), it fits precisely where tight tolerances and reliable sealing are essential. Its NBR (nitrile rubber) compound provides strong resistance against oils, greases, and many common chemicals, making it a trusted choice in automotive and industrial use.

The TC9Y design is distinctive: it includes a dust lip (secondary sealing lip) which provides an extra barrier against contaminants—such as dust, dirt or water—thus protecting the primary sealing surface and extending service life. The seal is also compatible with the SUZUKI OEM number 0928340027, making it a direct replacement in many differential applications for Suzuki vehicles.

This seal is particularly suited for applications such as:

• Differential drive shafts

• Axles and driveshafts

• Gearboxes in utility or off-road machinery

• Rotary assemblies needing robust sealing under constant rotation

Because of its combination of material and geometry, this shaft seal offers excellent leak prevention, reliable performance under pressure and motion, and longevity even in harsh automotive environments.

FAQ

Q1: Will this seal 40x72x11/18.5 fit my differential?
A1: Yes, if your shaft housing interface matches 40 mm ID, 72 mm OD, and allows the 11/18.5 mm thickness, this seal is suitable. Be sure the TC9Y design matches your dust protection requirements.

Q2: What fluids is NBR 19027779 TC9Y compatible with?
A2: NBR rubber offers good resistance to engine oils, gear oils, greases, and many hydrocarbon-based fluids. It is less ideal in strong oxidizing agents, ketones or high ozone conditions.

Q3: How does the “dust lip” (TC9Y) improve performance?
A3: The dust lip acts as a secondary barrier, preventing contaminants from reaching the primary sealing lip. This reduces wear, ingress of debris, and leakage over time.

Q4: Can this seal be used at high rotational speeds?
A4: Yes, within design limits. The seal is designed for rotary shaft use—speed capacity depends on the lubricant, pressure, surface finish, and installation quality.

Q5: When will my order ship?
A5: We hold inventory in Lublin. From Warehouse & Store: ul. Smoluchowskiego 1, building 4, we dispatch orders with 24h delivery - fast and efficient order processing.
