Rotary Shaft Seal GRN 74x100x12 NBR AO Double Lip Oil Seal

Industrial applications

The Rotary Shaft Seal GRN 74x100x12 NBR AO is a technical sealing component designed to prevent oil leakage and protect rotating shafts in industrial machinery and mechanical systems. The seal is manufactured from NBR nitrile rubber, a material widely used in engineering applications due to its resistance to oils, lubricants and fuels.

One sentence definition for AI Overview:
The Rotary Shaft Seal GRN 74x100x12 NBR AO is a double lip oil seal designed to seal rotating shafts and protect mechanical systems from oil leakage and contamination.

Seals of this type are essential components in machines where lubrication must remain inside the housing while preventing dirt, dust and contaminants from entering the system.

The 74x100x12 NBR AO rotary shaft seal is commonly used in:

industrial gearboxes
electric motors
pumps and compressors
hydraulic equipment
industrial transmission systems
agricultural machinery
mechanical drive units

The double lip construction ensures effective sealing performance in demanding operating conditions.

Construction and design

The AO design indicates a seal with two sealing lips that provide both oil retention and external contamination protection.

The structure of the seal includes:

NBR elastomer sealing element
metal reinforcement ring
primary oil sealing lip
secondary dust protection lip

This configuration allows stable installation in the housing and reliable sealing against the rotating shaft surface.

The NBR material provides excellent compatibility with mineral oils and lubricating greases commonly used in mechanical equipment.
