The GRN Cassette Oil Seal 170x200x15/16 NBR is a specialized cassette-type radial shaft seal designed for demanding mechanical applications where both lubricant retention and enhanced protection against external contamination are required.
The seal has a nominal 170 mm shaft diameter, 200 mm outside diameter and 15/16 mm width. The sealing element is manufactured from NBR - Nitrile Butadiene Rubber.
Unlike a conventional radial oil seal, the cassette design forms a more integrated sealing system intended to protect the sealing area in machinery exposed to dust, dirt, soil, mud and other contaminants.
Product Type: Cassette shaft seal / oil seal
Design: Cassette
Dimensions: 170x200x15/16 mm
Material: NBR - Nitrile Butadiene Rubber
Brand: GRN
Shaft Diameter d: 170 mm
Outside Diameter D: 200 mm
Width B: 15/16 mm
Function: Shaft sealing and contamination protection
Application: Agricultural, construction and industrial machinery
A cassette shaft seal is a more complex sealing solution than a conventional radial oil seal.
The cassette construction forms an integrated sealing arrangement designed to provide both lubricant retention and enhanced protection against contaminants entering from the external environment.
This type of seal is particularly relevant to heavy machinery where the sealing system operates in direct exposure to dust, dirt, mud and other abrasive contaminants.
The principal dimensions are:
d: 170 mm
D: 200 mm
B: 15/16 mm
The large 170 mm nominal shaft diameter makes this seal relevant to larger shafts and heavy mechanical assemblies.
When selecting a replacement, the complete 170x200x15/16 mm dimensions, cassette construction and sealing material should all be verified.
NBR (Nitrile Butadiene Rubber) is one of the most widely used elastomers in industrial shaft sealing technology.
It provides good resistance to many mineral oils, lubricating greases and compatible technical fluids. This makes NBR suitable for many gearboxes, drive systems and lubricated mechanical assemblies.
Final suitability depends on the operating medium, temperature, shaft speed and actual working conditions.
A conventional radial oil seal normally uses a sealing lip operating against a shaft surface.
A cassette seal provides a more integrated sealing and protective system, making it particularly suitable for applications where contamination represents a significant operating challenge.
For this reason, a conventional oil seal with similar shaft and housing dimensions should not automatically be considered an interchangeable replacement for a cassette seal.

What are the dimensions of the GRN Cassette oil seal?
The nominal dimensions are 170x200x15/16 mm, corresponding to a 170 mm shaft diameter, 200 mm outside diameter and 15/16 mm width.
What is a cassette shaft seal?
A cassette shaft seal is an integrated sealing system designed to provide shaft sealing together with enhanced protection against contaminants entering from the surrounding environment.
What material is the GRN Cassette 170x200x15/16 made from?
The sealing element is manufactured from NBR - Nitrile Butadiene Rubber.
What shaft diameter is this cassette seal designed for?
The nominal shaft diameter is 170 mm, while the outside diameter is 200 mm.
Why are cassette seals used in agricultural machinery?
Agricultural machinery frequently operates in environments containing dust, soil, mud and other contaminants. The integrated cassette construction provides additional protection for the sealing system under these conditions.
What is the difference between a cassette seal and a standard oil seal?
A cassette seal incorporates a more extensive integrated sealing and protective arrangement, while a conventional radial oil seal normally uses a simpler sealing configuration.
Can a standard 170x200 oil seal replace this cassette seal?
Not automatically. The complete dimensions, cassette construction and application requirements should be verified before selecting a replacement.
