How to Specify
For a complete coupling, order two hubs and one disk.
To order hubs, choose any bore size (inch, metric or mixed) available in the same outside diameter (OD). Part numbers are in the following format with an example of an inch to metric mixed coupling.


To order disk, choose material type and outside diameter (OD). Inch dimensions are on the left side of the “/” and metric sizes are on the right. For example:
