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.

order jcc

order mjcc

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:

order jd

Note 1 Hardware is alloy steel with black oxide finish.
Note 2 Performance ratings are for guidance only. The user must determine suitability for a particular application.
Note 3 Torque ratings for the couplings are based on the physical limitations/failure point of the spiders. Under normal/typical conditions the hubs are capable of holding up to the nominal torque of the spiders. In some cases, especially when the smallest standard bores are used or where shafts are undersized, slippage on the shaft is possible below the nominal torque of the spiders. Keyways are available to provide additional torque capacity in the shaft/hub connection when required. Please consult technical support for more assistance.
