Beam couplings connect rotating shafts and accommodate axial motion and parallel or angular shaft misalignment. They have a low maintenance, one-piece design that provides large misalignment capabilities. Beam couplings are frequently used in low torque applications that do not require excessive operating speeds, though some beam couplings can tolerate high torque applications. There are several types of beam couplings including flexible, slit and rigid. Each has unique features and performance capabilities to tackle issues such as misalignment and backlash in motion control applications. Common uses for beam couplings include encoders, pumps, and a range of other light-duty mechanical applications. When selecting a beam coupling, it is critical that you pay attention to the size and torque and speed rating to make sure it can handle the demands of your application.
