CX Coupler

Pre-assembled coupler. Designed to fit all shaft sizes

The UMC® CX Coupler is a shock-attenuating drive connection between the gearmotor and final drive gearbox. Its design reduces set up time for new center pivots and laterals. Similarly, it is the perfect compliment for towable systems due to the ability to control disengagement at the gearbox. From the service tech’s perspective, it is a must-have solution because this one coupler fits all brands of center pivots and laterals.


Our patented, preassembled drive connection fits a 3/4”, 7/8″, and 1” drive shafts as well as metric sizes. It features three 3/8″ SQUEX bolts for easy one wrench installation.
