CORTECO 12034432 PU 45x55.6x5.3/6.5 Polyurethane Radial Shaft Oil Seal

What Is the CORTECO 12034432 Oil Seal?

The CORTECO 12034432 is a polyurethane (PU) radial shaft oil seal designed for demanding sealing applications in agricultural and industrial machinery. With dimensions of 45x55.6x5.3/6.5 mm, it provides effective sealing between a rotating shaft and a stationary housing, preventing lubricant leakage while protecting the system against dust, dirt and moisture. This seal corresponds to Claas OEM part number 2150610 and is commonly used in agricultural equipment where durability and abrasion resistance are essential.

Polyurethane Seal Design

Unlike conventional NBR oil seals, the PU (Polyurethane) sealing lip offers significantly higher resistance to mechanical wear and abrasive contamination.

Key design features include:

• Polyurethane sealing element
• Precision sealing lip
• Reinforced construction
• Excellent wear resistance
• Designed for demanding operating environments
• Reliable protection against contamination

Polyurethane is frequently selected for applications exposed to dust, mud and intensive mechanical loading.
