How to Specify
For a complete coupling, order two hubs and one spider.
To order hubs, choose any bore sizes (inch or metric in any style) 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 spider, choose durometer and hub body size (OD). Inch dimensions are on the left side of the “/” and metric sizes are on the right. For example:
