Rotary Shaft Seal CORTECO 12010900 33x52x6 NBR BA Oil Seal

Product Overview

The CORTECO 12010900 33x52x6 NBR BA is a premium rotary shaft seal designed to provide reliable sealing performance in rotating shafts and mechanical systems. Manufactured from NBR (nitrile rubber), it ensures strong resistance to mineral oils, lubricants, and common industrial fluids, making it suitable for a wide range of automotive, hydraulic, and industrial applications.

The BA lip profile features a single sealing lip supported by a tension spring, ensuring consistent contact pressure on the shaft surface. This guarantees excellent leak prevention and protection against dust and contaminants entering the system.

Key Advantages

• High durability in standard operating temperature and speed conditions

• Reliable oil and grease resistance due to NBR rubber formulation

• Stable sealing performance thanks to the reinforced spring-loaded sealing lip

• Suitable for engines, gearboxes, pumps, compressors, and machinery

• Designed for long service intervals and reduced maintenance downtime

Technical Data

FAQ

1. What is the difference between a single lip and a double lip oil seal?
A single lip (BA) focuses on sealing fluids inside the system. A double lip (BASL/TC) includes a secondary dust lip for enhanced external contamination control.

2. When is NBR the right material choice?
NBR is ideal for operating temperatures up to ~100°C and environments exposed to oils and lubricants. For higher temperatures or aggressive chemicals, FPM/Viton® is recommended.

3. How do I ensure correct shaft seal installation?
Always use proper alignment tools and lubrication of the sealing lip to avoid premature wear or damage during installation.

4. What is this oil seal commonly used for?
It is widely used in automotive engines, transmissions, hydraulic pumps, industrial gearboxes, and rotating machinery.
