CORTECO 19016511 ACM RHTC Rotary Shaft Oil Seal 44x60x7 mm

What is the CORTECO 19016511 Oil Seal?

The CORTECO 19016511 is a radial shaft oil seal (simmerring) manufactured from ACM (polyacrylate rubber) in the RHTC sealing design. Measuring 44x60x7 mm, it is designed to provide dependable sealing between rotating shafts and stationary housings in automotive and industrial applications. The seal incorporates a right-hand hydrodynamic helix and an auxiliary dust lip, helping retain lubricant while protecting internal components from dust, dirt and moisture. ACM material is particularly suitable for oil-lubricated systems operating at elevated temperatures.

Construction and Operating Principle

The CORTECO 19016511 radial shaft seal is engineered to reduce lubricant leakage while preventing external contaminants from entering the sealing system.

Its construction includes:

• ACM (polyacrylate rubber)
• RHTC sealing profile
• Precision primary sealing lip
• Integrated auxiliary dust lip
• Right-hand hydrodynamic helix
• Rubber-covered outside diameter for secure housing installation

During shaft rotation, the hydrodynamic helix helps return lubricant toward the sealing lip, while the dust lip improves protection against contamination and extends seal service life.
