    To keep your shafts moving in sync, the flexible spring on these joints makes the output shaft move at the same rate as the input shaft. This spring also reduces vibration and compensates for more misalignment than standard single U-joints. However, these U-joints can’t handle as much torque. With zero backlash (no play), there’s no motion lost when you change direction. This keeps machines running smoothly with more accurate, repeatable motion. Made of stainless steel, these U-joints balance strength with good corrosion resistance.
    A good choice for optical devices and other sensitive equipment, these U-joints don’t require lubrication or gather dust and debris. They’re also easier to maintain than lubricated U-joints. They work well in assemblies that change frequently because you can quickly loosen their clamping screw to move them. This screw holds these U-joints in place without damaging your shafts. Unlike U-joints that use spring pins, there’s no drilling required.
    Your shafts’ misalignment will affect the speed and torque the U-joint will be able to transmit. The more the shafts are misaligned, the less speed and torque the U-joint will be able to transmit.
