Coupling assembly

(1)Clamping hub

(2)Elastomer spider

(3)Clamping hub

Coupling assemblies are required to mount motors to axes.

A coupling assembly consists of the following components:

•2 clamping hubs, one each for ball screw end and motor end

•1 elastomer spider, as a decoupling element between the hubs

•2 screws
