GRN® 35x65x14.5/17 KASSETTE NBR Rotary Shaft Cassette Seal

Overview

GRN® 35x65x14.5/17 KASSETTE NBR is an integrated rotary shaft cassette seal designed for demanding applications where lubricant retention and protection against external contamination are both required. The 35 mm shaft diameter, 65 mm housing diameter and 14.5/17 mm axial dimensions identify this specific sealing system. Its cassette construction provides a more integrated sealing arrangement than a conventional radial shaft seal.

Industrial Applications

The GRN® 35x65x14.5/17 cassette seal is suitable for hubs, axles, transmissions, agricultural machinery, construction equipment and heavy-duty rotary assemblies. Cassette sealing systems are particularly useful where the shaft area is exposed to dust, dirt, mud, water or other external contamination that can reduce the service life of a conventional oil seal.

Construction

The KASSETTE design combines multiple interacting sealing elements within an integrated assembly. Unlike a standard single or double lip oil seal, a cassette seal can provide additional contamination barriers and controlled running surfaces. This configuration protects the primary sealing zone while retaining oil or grease inside the mechanical assembly.

Material

NBR, or Nitrile Butadiene Rubber, provides good resistance to many mineral oils, lubricating greases and compatible industrial fluids. It also offers useful wear resistance and mechanical stability for industrial sealing. Actual temperature capability depends on the specific NBR compound, lubricant, shaft speed and operating environment.

Why Industrial Buyers Choose This Product

GRN® 35x65x14.5/17 KASSETTE NBR is suitable for OEM replacement, maintenance stock, industrial service, machine rebuilding, production support and fleet maintenance. Its integrated cassette construction is particularly relevant where a standard radial shaft seal does not provide sufficient protection against external contamination. Defined dimensions support accurate identification during equipment repair and overhaul.

Operational Advantages

• Integrated cassette design provides multiple barriers against contamination.
• NBR offers good resistance to many mineral oils and lubricating greases.
• Additional sealing elements help protect the primary sealing zone.
• 35x65x14.5/17 mm dimensions enable precise replacement identification.
• Cassette construction suits equipment exposed to dust, mud and water.
• Integrated running surfaces can reduce dependence on the condition of the original shaft sealing track.

FAQ

What are the dimensions of this GRN® KASSETTE seal?

The nominal shaft diameter is 35 mm, housing diameter is 65 mm and the specified axial dimensions are 14.5/17 mm.

How does a cassette seal differ from a conventional oil seal?

A cassette seal is an integrated sealing system with multiple interacting components and contamination barriers rather than a conventional single sealing element.

Where is the 35x65x14.5/17 cassette seal typically used?

It is suitable for correctly matched hubs, axles, transmissions and machinery operating in contaminated environments.

Why is a cassette design useful in agricultural and construction machinery?

These machines frequently operate in dust, mud, water and dirt, making additional contamination barriers valuable for protecting the primary sealing zone.

Can a conventional 35x65 radial shaft seal replace this cassette seal?

Not automatically. The cassette construction, axial dimensions, running surfaces and installation arrangement must all be verified before selecting a replacement.
