UMC Driveline Couplers

Standard Flex Coupler Designed for use as a coupler between the gearmotor and final drive gearbox. UMC's Standard Coupler is a shock-attenuating drive connection between the gearmotor and final drive gearbox. It has been the industry standard for many years on new systems from Original Equipment Manufacturers. It is available in a wide variety of sizes and configurations to fit any brand of center pivots and laterals. UMC's Standard Coupler features an alignment rod that helps keep concentric positioning under extreme loads. The added strength is ideal in heavy soils and on systems with larger-diameter tires. Features and Benefits
Proven service record of over 25 years
Designed for extreme duty environments
Ideal for high torque low speed conditions
Alignment rod holds insert in place and coupler in alignment under extreme or sudden loads.
Designed for use in extreme duty environments: heavy soils; Larger tire diameter; Higher torque motors; and stronger gearboxes.
Designed to be the fusible link in the drive train to prevent failure in final drive gearbox or other hardware in problematic field conditions.
Urethane insert offers an environmentally stable material with better resistance to UV rays and chemicals.
Grooved insert option converts any coupler assembly for a towable application.
UMC SQUEX-bolts (Square-Neck, Hex-Head) creates unique bolt anti-rotation feature that allows for faster single wrench assembly in Field.
High torque conditions capture and compress insert lobes instead of shearing them.

Ideal for high-torque, slow-speed conditions with severe back driving.
Curved pressure pads compensate for out of line conditions.
One year limited warranty. UMC was the first to introduce the shock attenuating coupler with a flexible insert. This drastically improved gearbox life and significantly reduced maintenance time and cost.
