CORTECO 12020351 RWDR-K7 48x75x14/17 FPM rotary shaft seal

Main Description

The CORTECO 12020351 RWDR-K7 48x75x14/17 is a high performance rotary shaft seal made of FPM, designed for demanding drivetrain and axle applications requiring superior resistance to temperature, pressure, and aggressive media.

This specific model stands out within the Corteco simmerring seals category due to its RWDR-K7 construction, which enhances sealing efficiency in dynamic environments. The size 48x75x14/17 is widely used in heavy duty systems such as axles and gearboxes, particularly in machinery equipped with CARRARO components.

The use of FPM material, also known as fluorocarbon rubber, significantly increases resistance to high temperatures, synthetic oils, fuels, and chemically aggressive environments. This makes the seal ideal for applications where standard NBR seals would degrade faster.

The CORTECO 12020351 provides reliable sealing in both industrial and off highway applications, ensuring long service life and consistent performance under variable load conditions.

Construction and Design

The RWDR-K7 design offers advanced sealing characteristics:

• multi lip sealing system for enhanced oil retention
• integrated dust protection elements
• reinforced metal casing for dimensional stability
• optimized sealing lip geometry for high speed operation
• designed for demanding axial and radial load conditions

This design ensures effective sealing even in applications exposed to contamination, vibration, and fluctuating pressures.

Industrial Applications

The CORTECO 12020351 seal is commonly used in:

• axle systems and drivetrain components
• agricultural and construction machinery
• gearboxes and transmission systems
• CARRARO axles and drive assemblies
• equipment operating in high temperature environments

Its presence in the Corteco seal cluster strengthens the segment of FPM based high performance seals for advanced industrial use.
