Clamp-Style Control-Flex Couplings



Clamp-style couplings attach an encoder shaft to another rotating shaft to transfer rotation between the 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. Using Control-Flex couplings will help extend the operational life of your encoder and guarantee accuracy.

Clamp 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 pins. Clamp-style hubs provide a positive, secure shaft connection. The clamp-style Control-Flex Couplings are available with a single flex disc for standard torque capacity, or with two flex discs for increased torque capacity, torsional stiffness, and length.

Specification range for double disc couplings

  • maximum parallel shaft misalignments of 0.009” to 0.037”
  • maximum peak torque of 10 in-lbs to 650 in-lbs
  • maximum speed of 4,000 to 10,000 RPM

Specification range for single disc couplings

  • maximum parallel shaft misalignments of 0.013” to 0.055”
  • maximum peak torque of 6 in-lbs. to 361 in-lbs.
  • maximum speed of 5,000 to 12,000 RPM

The clamp-style hub models come standard without keyways. Keyways and special modifications are available upon request. View the individual product specifications below for additional information.
