CORTECO 49482285 NBR RWDR-K7 RWDR-KASSETTE Cassette Seal

What Is the CORTECO 49482285 Cassette Seal?

The CORTECO 49482285 is a cassette shaft seal manufactured in the RWDR-K7 (RWDR-KASSETTE) design. It is intended for demanding sealing applications in agricultural and off-highway machinery where rotating shafts are exposed to dirt, mud, water and heavy operating conditions. Manufactured from NBR (Nitrile Butadiene Rubber), the seal provides reliable lubricant retention while protecting bearings and drivetrain components against external contamination. This seal corresponds to New Holland OEM number 89823545.

RWDR-K7 Cassette Seal Construction

The RWDR-K7 cassette design combines several sealing elements into one assembly.

Main construction features:

• RWDR-K7 cassette seal design
• Integrated multi-lip sealing system
• Dirt exclusion lips
• Precision running surface
• NBR sealing material
• Metal reinforcement
• Designed for harsh operating environments

The cassette construction protects the sealing lip from external contamination while maintaining stable sealing performance during continuous operation.

How Does a Cassette Seal Work?

Unlike a conventional radial shaft seal, a cassette seal incorporates multiple sealing and protective elements into one unit.

Its construction:

• retains lubricants,
• prevents dirt ingress,
• protects against mud and water,
• shields bearings from contamination,
• extends component service life,
• reduces maintenance requirements.

This makes cassette seals particularly suitable for agricultural and construction machinery operating in severe environments.

Why Choose NBR?

NBR is widely used for cassette seals because it provides:

• excellent resistance to mineral oils,
• good grease compatibility,
• high abrasion resistance,
• good mechanical strength,
• reliable elasticity,
• stable sealing performance under normal operating temperatures.

These properties make NBR suitable for most transmission and axle sealing applications.

Typical Applications

The CORTECO 49482285 cassette seal is commonly used in:

• Agricultural machinery
• New Holland equipment
• Drive axles
• Final drives
• Wheel hubs
• Gearboxes
• Heavy-duty transmissions
• OEM machinery
• Industrial maintenance
• MRO service

Compatibility is based on New Holland OEM reference 89823545.

Installation Guidelines

Before installation, verify:

• Shaft diameter
• Housing bore
• Seal dimensions
• Shaft condition
• Housing cleanliness
• Proper installation tools

Cassette seals should always be installed squarely to ensure proper sealing and maximum service life.
