CORTECO 12000727 BASL Rotary Shaft Seal 44.5x62x10/8 ACM

High Performance Rotary Shaft Seal for Agricultural Drive Systems

The CORTECO 12000727 BASL rotary shaft seal is a precision engineered oil seal designed for demanding rotating equipment operating in agricultural and industrial power transmission systems. Manufactured from ACM polyacrylate elastomer and equipped with an additional dust lip, this radial shaft seal provides reliable lubricant retention while protecting bearings and rotating shafts against dirt, dust and moisture. The design is suitable for differential units, drive axles, gearboxes and transmission assemblies where long service life and dependable sealing performance are required. It is referenced as NEW HOLLAND OEM 5112012.

Application in Industrial Systems

This rotary shaft seal is used in rotating mechanical assemblies where lubrication must remain inside the housing while contaminants remain outside.

Typical applications include:

• Agricultural machinery transmissions
• Differential assemblies
• Drive axle systems
• Gearboxes
• Final drive units
• Power transmission equipment
• Industrial machinery
• Heavy-duty maintenance operations

The BASL construction makes this oil seal suitable for environments exposed to dust, mud and agricultural contamination.

Construction and Design

CORTECO BASL seals are designed for dynamic rotary sealing applications.

Key construction features include:

• Rotary shaft seal
• Radial shaft seal
• Oil seal with primary sealing lip
• Integrated dust lip
• Spring energized sealing lip
• Precision molded ACM elastomer
• Steel reinforcing insert
• Designed for bidirectional shaft rotation in lubricated systems

The BASL profile improves contamination resistance compared with single lip shaft seals while maintaining stable contact pressure throughout service life.

Material Properties

The sealing element is manufactured from ACM Polyacrylate rubber.

Advantages of ACM include:

• Excellent resistance to transmission oils
• High resistance to gear lubricants
• Very good ageing resistance
• Stable performance at elevated temperatures
• Low compression set
• Reliable sealing in agricultural equipment
• Long operating life in gearbox applications

Compared with conventional NBR seals, ACM provides superior thermal resistance for continuously loaded transmission systems.
