circularsiliconerubber

Special built-in vacuum cups with ball valve Their main feature is that they open suction and therefore they produce a vacuum, only when the load to be handled activates the sealing ball. Especially designed for the vacuum operated beds of woodworking machines, they differ from the previously described ones because of the high precision of their cylindrical support, which is ground to size, and because of their square closing block, which prevents the cup from rotating and enables connection to vacuum. The cold fitted cups are the flat ones listed in the table, in the various compounds. The support of these cups is made of anodised aluminium, while the closing block is made of brass.
