GRN 190x220x16/18 NBR Cassette Rotary Shaft Oil Seal

Premium Radial Rotary Shaft Seal for Harsh Industrial Conditions

GRN 190x220x16/18 NBR is a heavy duty cassette rotary shaft oil seal designed for demanding industrial and agricultural machinery where reliable protection against lubricant leakage and external contamination is essential. The cassette seal construction integrates the sealing element with a protective counterface system, creating a durable sealing solution for rotating shafts.

A cassette oil seal is an advanced type of rotary shaft sealing system used in machines exposed to harsh environments such as dust, mud and moisture. The GRN 190x220x16/18 NBR cassette seal is designed to maintain lubrication inside mechanical assemblies while protecting bearings and drivetrain components from contamination.

This sealing solution is widely used in agricultural equipment, construction machinery and industrial drivetrain systems where standard oil seals may not provide sufficient durability.

Construction and cassette seal design

Cassette oil seals belong to the most robust sealing solutions used in rotating machinery. Their design differs from conventional simering seals because the sealing lip works together with an integrated counterface sleeve.

Key construction elements include:

reinforced metal housing for secure installation
sealing element made from NBR elastomer
integrated counterface sleeve protecting the shaft
multi lip sealing system for improved contamination resistance

This design forms a multi barrier protection system that prevents the entry of:

dust and abrasive particles
mud and soil contamination
water and moisture
industrial debris

By isolating the lubricated internal environment from external contamination, cassette seals significantly increase the service life of shafts, bearings and gearbox components.

Application in industrial and agricultural machinery

Cassette rotary shaft seals are commonly used in machines operating in environments where high contamination levels are present.

Typical applications include:

agricultural machinery
tractors and combine harvesters
wheel hub and axle systems
construction equipment drivetrains
industrial rotating shaft systems

In these applications the cassette oil seal protects lubrication systems and prevents damage caused by external contaminants entering the mechanical assembly.

Technical specifications

Product type: cassette rotary shaft oil seal
Brand: GRN

Inner diameter: 190 mm
Outer diameter: 220 mm
Width: 16/18 mm

Sealing material: NBR nitrile rubber

Application: sealing rotating shafts in industrial and agricultural machines

NBR material provides excellent resistance to:

mineral oils
industrial lubricating greases
mechanical wear
moderate operating temperatures

Because of these properties NBR is one of the most widely used materials in industrial sealing systems.

Operational advantages of cassette sealing systems

Cassette seals provide superior durability compared to standard rotary shaft oil seals used in simpler applications.

Key advantages include:

high resistance to environmental contamination
protection of shaft surface through integrated counterface
extended service life of bearings and drivetrain components
stable sealing performance under heavy operating conditions
effective oil retention inside mechanical systems

These features make cassette seals a preferred solution for maintenance and repair of heavy duty machinery.

FAQ - technical questions about the 190x220x16/18 cassette seal

What is a cassette oil seal?

A cassette oil seal is a rotary shaft seal that combines a sealing lip with an integrated counterface sleeve, providing improved protection against contamination and lubricant leakage.

Where are cassette seals commonly used?

They are widely used in agricultural machinery, construction equipment, industrial gearboxes and heavy duty rotating machinery.

Is NBR suitable for industrial oil seals?

Yes. NBR nitrile rubber offers strong resistance to oils and greases and is commonly used for sealing rotating shafts in mechanical systems.

Can the 190x220x16/18 seal be used in different machines?

Yes, provided that the shaft diameter, housing diameter and seal width correspond to the dimensions 190x220x16/18.

Why are cassette seals more durable than standard oil seals?

Because they include an integrated counterface and additional protective lips which improve resistance to contamination and mechanical wear.
