Behind the scenes, the equipment that makes possible thousands of tests results for clinical trials, dispenses tens of thousands of exact liquid doses in individual containers, and moves the machines that test and review our bodies requires motion control precision with zero backlash. This zero backlash directly relates to installing the proper coupling between motors and moving parts. These motion control couplings are available in several different styles, including beam, oldham, mini-jaw, bellows, mini-soft, mini-disc and curved jaw. High-speed operations, for example, can look to the GS curved jaw mini-coupling, with a maximum 31,800 RPM. The bellows clamp style coupling specifically addresses higher torque and bore capacities.
