CORTECO 01002480 30x40x7 NBR B1 Radial Shaft Seal

Application - Radial Shaft Seal for Engines and Industrial Systems

The CORTECO 01002480 30x40x7 NBR B1 is a precision radial shaft seal designed for dynamic sealing in automotive and industrial applications. With dimensions 30x40x7 mm, this oil seal is commonly used in engines, gearboxes, and rotating machinery where reliable shaft sealing is essential.

As a single lip radial shaft seal, it effectively retains lubricants inside the system while preventing oil leakage along rotating shafts. The design without a defined rotation direction allows installation in assemblies operating in both clockwise and counterclockwise movement.

This component corresponds to OEM references such as Mercedes A0089977346, 0089977346 and Renault Trucks 5000589262, confirming its suitability for professional automotive and commercial vehicle applications.

B1 Design - Reliable and Efficient Technical Seal

The B1 construction refers to a single lip oil seal equipped with a garter spring that maintains constant radial pressure on the shaft. This ensures stable oil retention under standard operating conditions.

Compared to a double lip oil seal, the B1 version does not include an auxiliary dust lip. It is therefore suitable for cleaner environments or systems where additional contamination protection is not required.

Manufactured from NBR, the seal provides good resistance to oils and grease, fuels, and typical industrial lubricants. The metal outer case ensures secure press-fit installation and dimensional stability within the housing bore, contributing to high durability and long service life.

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 contamination protection.

How do I select the correct shaft seal size?
The first dimension (30 mm) is the shaft diameter, the second (40 mm) is the housing bore, and the third (7 mm) is the seal width.

Is NBR suitable for engine oil applications?
Yes. NBR offers reliable resistance to oils and grease within standard automotive and industrial temperature ranges.

Can this seal be used in industrial machinery?
Yes, it is widely used in industrial applications where standard rotary sealing performance is required.
