A new clamp design for zero-backlash flexible beam couplings is now available. The couplings clamp with a single screw on each end, which eases installation. The beam couplings feature both a radial and cross-cut to enhance surface contact with the shaft. This increases holding power while eliminating the need for the additional screw used in the original design. Balancing is achieved by the removal of material opposite the screw. Better balancing allows for increased speed with less vibration.

Two series of these zero backlash flexible beam couplings are offered for different types of applications. Available in aluminum for low inertia or stainless steel for higher torque and added corrosion-resistance, the couplings are available as standard parts in twenty different body sizes, with outside diameters ranging from 3/8 in. (10 mm) to 1 ½ in. (38 mm), and bores from 3/32 in. (2 mm) to ¾ in. (19 mm).
