The VMECA Ball-Joint referred to as a universal joint is for use when a degree of angular compliance is required, more commonly used with flat type cups which unlike bellows do not allow for much angular compliance as part of their design. The vacuum port is integral through the center of the joint thus providing a neat and compact solution.
The VMECA level compensator is used to compensate for differences in height on the surface of the material that is to be lifted. The advantages being a more reliable and less precise pick up position when handling product that may be less consistent in it shape, size and position. The level compensator also provides a degree of shock absorption should this be required. The level compensator come in configurations with varying sizes of spring and stroke.
