CORTECO 12019514 Rotary Shaft Seal 40x80x14/15 FPM (RWDR-K7)

Applications

The CORTECO 12019514 rotary shaft seal (RWDR-K7) in size 40x80x14/15 is designed for sealing rotating shafts in drive systems, gear housings, and powertrain components. It is commonly used in agricultural machinery, including NEW HOLLAND models referring to OEM numbers 82019514 and 47134818. Its role is to protect lubricated components, such as bearings and transmission shafts, from oil leakage while preventing dust, mud, and environmental contaminants from entering the system. This ensures stable operation and prolongs the service life of critical moving parts.

Advantages

Manufactured from FPM (fluoroelastomer), this seal offers excellent resistance to engine oils, hydraulic fluids, and elevated temperatures. The RWDR-K7 sealing profile supports durability under rotational load, pressure fluctuations, and continuous lubrication. Its material composition ensures reduced hardening over time, improved dimensional stability, and high resistance to wear and chemical degradation. This results in lower maintenance frequency and improved reliability of the machinery it serves.

Main Description

The CORTECO 12019514 rotary shaft seal is engineered for demanding mechanical environments where long-term sealing reliability is required. Installed in rotating assemblies, this seal performs a dual function: retaining lubricants inside the housing and preventing contamination from traveling along the shaft surface. This is especially critical in agricultural and industrial machinery, where equipment operates in dusty, muddy, or variable weather conditions.
The RWDR-K7 lip design promotes consistent sealing performance across varying shaft speeds and lubrication states. Combined with FPM material, it delivers strong resistance to thermal stress, oxidative aging, and fuel or oil exposure. These attributes make it particularly suited for NEW HOLLAND powertrain systems, where durability and operational continuity are essential.
By maintaining proper lubrication levels and protecting bearings from contaminants, this seal helps reduce the risk of premature wear, vibration, overheating, and downtime. It is suitable for both OEM replacement and preventive maintenance programs in professional agricultural and industrial operations.

FAQ

Is this seal compatible with NEW HOLLAND machinery?
Yes. It corresponds to OEM numbers 82019514 and 47134818.

Why is FPM material important?
FPM provides superior resistance to oils, heat, and chemical degradation, extending seal life.

Can this seal replace an NBR version?
Yes, where higher temperature and oil resistance is required.

Does it help protect bearings and shaft surfaces?
Yes. Proper sealing reduces contamination and improves bearing longevity.
