Vacuum cup holder 029528

Basic anti-rotation vacuum cup holders The technical features are the same as for the previously described basic vacuum cup holders. Their distinctive features are their brass stem with hexagonal cross-section and the steel drive bush, also with hexagonal hole. This structure prevents the stem and, as a consequence, the cup assembled onto it from rotating on its axis. The drive bush is equipped with two fine thread ring nuts to guarantee an accurate fastening of the cup holder to the automation. They are suited for cups with diameters between 45 mm and 110 mm, although they have been specially designed for assembling rectangular, concave or elliptical cups. The actual springing stroke is: - For height C= 28 mm 16 mm - For height C= 65 mm 49 mm - For height C= 95 mm 74 mm
