Overview
GRN 150x180x14.5/16 NBR KASSETTE is a specialized cassette shaft seal for hubs and axles, designed for demanding mechanical applications where effective lubricant retention and enhanced protection against external contamination are required.
The seal has a nominal 150 mm inside diameter, 180 mm outside diameter and 14.5/16 mm width. Its sealing components are manufactured from NBR - Nitrile Butadiene Rubber.
The integrated KASSETTE design is particularly relevant to hub and axle assemblies operating in environments exposed to dust, dirt, soil, mud and other contaminants.

KASSETTE Design for Hubs and Axles
The KASSETTE design provides a more extensive sealing arrangement than a conventional radial oil seal.
Its integrated construction is designed to retain lubricant within the mechanical assembly while providing additional protection against contaminants entering from the surrounding environment.
This is particularly important in hub and axle assemblies, which may operate in direct exposure to dust, water, soil, mud and abrasive contaminants.
150x180x14.5/16 mm Dimensions
The principal dimensions are:
d: 150 mm
D: 180 mm
B: 14.5/16 mm
The seal has a nominal 150 mm inside diameter and 180 mm outside diameter.
The complete 14.5/16 mm width designation is an important identification parameter resulting from the cassette seal geometry. When selecting a replacement, the complete 150x180x14.5/16 mm specification should be verified.
NBR Sealing Material
NBR (Nitrile Butadiene Rubber) is widely used in industrial shaft, hub and axle sealing systems.
It provides good resistance to many mineral oils, lubricating greases and compatible technical fluids. This makes NBR suitable for numerous lubricated mechanical systems, including transmissions, axle assemblies and hubs.
Final material suitability depends on the operating medium, temperature, rotational speed and actual application conditions.
Cassette Sealing for Hub Assemblies
Hub assemblies in agricultural, construction and heavy-duty machinery frequently operate in highly contaminated environments.
An effective sealing system must help retain lubricant inside the hub while reducing the ingress of contaminants that could reach bearings and other internal components.
The integrated cassette construction makes this sealing concept particularly relevant to such demanding applications.
Cassette Sealing for Axles
Axle sealing points can be exposed to a combination of rotation, lubricant and external contamination.
The GRN KASSETTE 150x180x14.5/16 provides an integrated sealing arrangement designed for applications where both lubricant retention and environmental protection are important.
Correct dimensions and installation geometry should always be verified for the specific axle assembly.
KASSETTE vs Standard Oil Seal
A conventional radial oil seal typically provides dynamic sealing between a rotating shaft and stationary housing.
A KASSETTE seal incorporates a more extensive integrated sealing and protective arrangement.
For this reason, a conventional 150x180 oil seal should not automatically be considered an interchangeable replacement for the GRN KASSETTE 150x180x14.5/16.
Heavy-Duty Applications
The GRN cassette seal can be used in appropriately designed:
- Hub assemblies
- Axle assemblies
- Agricultural machinery
- Construction machinery
- Heavy-duty drive systems
- Large rotating mechanisms
- Industrial machinery
- Equipment operating in dusty and contaminated environments
Operational Advantages
- Integrated KASSETTE construction.
- 150x180x14.5/16 mm dimensions.
- NBR sealing material.
- Suitable for hub and axle sealing applications.
- Effective lubricant retention.
- Enhanced protection against external contamination.

FAQ
What are the dimensions of the GRN KASSETTE seal?
The nominal dimensions are 150x180x14.5/16 mm, corresponding to a 150 mm inside diameter, 180 mm outside diameter and 14.5/16 mm width.
Is the GRN 150x180x14.5/16 designed for hubs and axles?
It is a cassette-type sealing construction intended for appropriately designed mechanical assemblies, including hub and axle applications requiring lubricant retention and enhanced contamination protection.
What does KASSETTE mean?
KASSETTE identifies an integrated cassette-type sealing construction that combines the primary sealing function with additional protection against external contamination.
What does the 14.5/16 mm width designation mean?
It represents the complete width specification associated with the geometry of the cassette seal. This designation should be retained when identifying a replacement.
What material is this cassette seal made from?
The sealing components are manufactured from NBR - Nitrile Butadiene Rubber.
Why are cassette seals used in hub assemblies?
Cassette seals provide an integrated sealing and protective system that helps retain lubricant while reducing the ingress of dust, dirt, soil, mud and other contaminants.
Can a standard 150x180 oil seal replace this KASSETTE seal?
Not automatically. The complete 150x180x14.5/16 mm dimensions, cassette construction and application requirements should be verified before selecting a replacement.
