Its nitrile rubber compound provides strong resistance to oils, fuels, and greases, making it a dependable component in powertrain and mechanical systems.

Ideal for use in engines, small gear drives, and agricultural machinery, this seal is frequently applied as a replacement for OEM references from MERCEDES-BENZ, PIAGGIO, and SAME. The BARD profile supports stable lip elasticity and optimized contact pressure, ensuring reduced wear during continuous operation. With balanced material hardness and flexibility, the CORTECO 12011222 maintains long-term sealing efficiency even in challenging operating conditions.

This oil seal is suitable for workshops, service centers, equipment manufacturers, and B2B buyers who prioritize precision, durability, and consistent performance. Its design ensures that rotating components remain properly lubricated and protected, reducing maintenance intervals and extending component life. As a technical seal used in both industrial applications and engine systems, it provides reliable protection where high-quality rotary sealing is essential.

FAQ - Frequently Asked Questions

1. What is the difference between a single-lip and double-lip oil seal?
A single-lip (SC) seal retains the medium (oil or grease), while a double-lip (TC) seal adds a secondary dust lip that improves protection against external contaminants.

2. Why choose NBR material for this shaft seal?
NBR offers excellent resistance to oils, lubricants, and fuels, making it ideal for medium-temperature rotary applications and engine components.

3. How do I select the correct shaft seal size?
Match three key parameters: inner diameter (shaft size), outer diameter (housing fit), and width. Material selection is also crucial for temperature and chemical resistance.

4. Where is the 24x35x6 NBR oil seal commonly used?
In small engines, gear systems, mechanical drives, agricultural machinery, and various automotive components requiring reliable rotary sealing.
