Advantages - FPM Material and BAVIRSX7 Design

Manufactured by CORTECO, a globally recognized seal manufacturer, this model is produced from high-performance FPM (FKM, Viton) material. FPM offers excellent resistance to oils and grease, high temperatures, and aggressive chemical media, making it ideal for heavy-duty applications.

The BAVIRSX7 design represents an advanced double lip oil seal configuration with reinforced structure and optimized sealing geometry. The primary lip, supported by a garter spring, ensures consistent radial pressure on the shaft, while the additional lip enhances contamination protection. This technical seal solution provides high durability and reliable long-term performance.

Main Description

The CORTECO 12013550 FPM 100x120x10 rotary shaft seal is designed for high-load and high-temperature operating conditions. As a professional oil seal, it provides effective shaft sealing in heavy-duty vehicles and industrial machinery.

Compared to standard NBR seals, FPM material offers superior thermal and chemical resistance, ensuring stability in continuous-duty environments. This makes it suitable for gear oil applications, transmission systems, and mechanical assemblies exposed to demanding operational stresses.

The BAVIRSX7 construction enhances sealing reliability by maintaining stable contact pressure and protecting against external contamination. When installed in a properly machined housing and used in conjunction with ball bearings or complete bearing units, it supports system integrity and reduces the risk of oil leakage.

This seal is widely selected by OEM manufacturers, fleet maintenance operators, and industrial service engineers who require high durability and dependable performance in automotive and industrial applications.
