Motor shaft couplings have to strike a delicate balance when it comes to stiffness. On the one hand, they have to be rigid enough to transmit torque efficiently. On the other, they have to be flexible enough to handle any misalignment between the motor and the drive shaft. Our latest coupling design can help you strike that balance.

The big gearboxes that drive cable drums do not come cheap. Yet engineers often make a design mistake that can shorten the gearbox’s working life. This mistake involves the use of a rigid, direct coupling between the gearbox output shaft and the cable drum.

 Heavy-duty shaft couplings have traditionally had a couple of defining design characteristics. For one, these couplings usually rely on keyed shaft connections. For another, they tend to be overengineered with regard to stiffness.
