Bolted-style flexible couplings transfer rotation between two shafts in a precise manner. They also reduce wear and tear on bearings that can lead to costly maintenance and reduced life of your encoder. A bolted-style coupling allows for larger shaft misalignments than clamp style couplings and can handle larger shafts and higher torques. Using Control-Flex® Couplings will help extend the operational life of your encoder and guarantee accuracy.

Bolted-Style Flex Coupling Features

The construction of a Control-Flex® Coupling consists of two hubs (that attach to the shafts) and a center flex member. This flexible element is affixed to the hubs through shoulder bolts. The bolted-style hubs incorporate a keyway and setscrew shaft attachment. Flex discs are bolted for drop-out capability, for easy installation and maintenance. This unique design means the reaction forces due to transmission of torque and unavoidable shaft misalignments are considerably smaller when compared with common flexible couplings.

Zero-Max bolted-style Control-Flex® Couplings were designed for encoder and instrumentation type applications. We offer couplings in four sizes that allow for maximum parallel shaft misalignments from 0.055” to 0.139,” maximum peak torques from 361 to 5,638 in-lbs., and maximum speeds from 2,500 to 6,300 RPM.

Choosing the Right Bolted-Style Coupling

To make sure you are choosing the correct size bolted-style coupling for your encoder or machinery, you first need to identify your application’s requirements for torque, misalignment, and service factor, then find a coupling from the options below based on those requirements. Next, you will need to compute the misalignment ratio and torque ratio using the selection procedures we have provided on page 7 of our product brochure, then use the chart to compare the ratios to the coupling’s operating envelope.

If the ratios for your application fall into the shaded area, exceeding the maximum values of your chosen coupling, you will need to select the next size up and redo the calculations to ensure you are choosing the proper coupling.
