GRN 167.8x198x13/15.5 NBR Cassette Oil Seal - RWDR KASSETTE

Product Overview

GRN 167.8x198x13/15.5 NBR is a heavy-duty cassette oil seal for rotary shafts, designed for demanding industrial, agricultural and mobile machinery applications. Its RWDR KASSETTE / CASSETTE construction combines the primary radial sealing function with additional protection against external contamination.

The seal has nominal dimensions of 167.8x198x13/15.5 mm and is manufactured from NBR (Nitrile Butadiene Rubber), a widely used sealing material with good resistance to many mineral oils, greases and compatible industrial lubricants.

The cassette construction is particularly suitable for machinery operating in environments exposed to dust, dirt, mud and moisture.

RWDR KASSETTE - Heavy-Duty Rotary Shaft Sealing

A conventional radial shaft seal normally operates directly against a prepared shaft surface. A cassette seal is a more complex integrated sealing system incorporating sealing and protective elements together with its own mating surface.

This construction helps isolate the primary sealing area from external contamination and provides additional protection in severe operating environments.

For this reason, RWDR KASSETTE seals are commonly selected for heavy machinery where conventional oil seals may be exposed to significant contamination.

GRN 167.8x198x13/15.5 Cassette Seal

The primary identification parameters for this product are:

GRN + 167.8x198x13/15.5 + NBR + RWDR KASSETTE

The complete dimensions are important when selecting a replacement. Two cassette seals with similar shaft and housing diameters are not necessarily interchangeable because their width, internal geometry and sealing configuration may differ.

NBR Sealing Material

NBR - Nitrile Butadiene Rubber is one of the most widely used elastomers in industrial rotary shaft sealing technology.

It provides good resistance to many:

• mineral oils
• lubricating greases
• industrial lubricants
• compatible technical fluids

NBR also provides useful mechanical and wear resistance for demanding machinery applications.

Actual suitability depends on the operating temperature, shaft speed, lubricant or medium and specific working conditions.

Applications

The GRN 167.8x198x13/15.5 NBR cassette oil seal is intended for appropriately designed sealing positions in:

• agricultural machinery
• construction equipment
• industrial machinery
• axles and hubs
• gearboxes
• transmission systems
• heavy-duty rotating equipment
• machinery operating in dusty and contaminated environments

Cassette sealing technology is particularly useful where the sealing position requires greater environmental protection than a conventional radial shaft seal can provide.

Why Choose a Cassette Oil Seal?

The main advantage of this product is its integrated cassette construction, rather than simply its dimensions.

Compared with a standard radial shaft seal, the cassette system provides a more comprehensive sealing arrangement designed to protect the primary sealing zone against:

• dust
• dirt
• mud
• water and moisture
• external contamination

This makes cassette seals particularly valuable in heavy-duty machinery, agricultural equipment and industrial drive systems.

Operational Advantages

• Integrated RWDR KASSETTE construction.
• Precise 167.8x198x13/15.5 mm dimensions.
• NBR material suitable for many oils and greases.
• Additional protection against external contamination.
• Integrated mating surface.
• Designed for rotary shaft applications.
• Suitable for severe industrial environments.
• GRN® industrial sealing solution.

FAQ

What is the GRN 167.8x198x13/15.5 seal?
It is a cassette-type rotary shaft oil seal with an RWDR KASSETTE construction, designed for demanding machinery applications.

What are the dimensions of this cassette seal?
The nominal dimensions are 167.8 mm shaft diameter, 198 mm housing diameter and 13/15.5 mm width.

What material is the seal made from?
This version is manufactured from NBR (Nitrile Butadiene Rubber).

What does RWDR KASSETTE mean?
RWDR KASSETTE identifies a cassette-style radial shaft sealing system incorporating sealing and protective elements into an integrated assembly.

How does a cassette seal differ from a standard oil seal?
A cassette seal provides a more comprehensive sealing system with an integrated mating surface and additional protective elements. This helps protect the primary sealing area against external contamination.

Where are cassette oil seals commonly used?
Typical applications include agricultural machinery, construction equipment, axles, hubs, gearboxes, transmission systems and heavy industrial machinery.

Can I select this seal only by the 167.8x198 mm diameters?
No. The complete 167.8x198x13/15.5 mm dimensions, cassette design, material and application requirements should be verified before replacement.
