SKH-25 silicone 2.5 bellows vacuum cup unit

The FIPA SKH is a series of bellows vacuum cups. The 2.5 in the name refers to the number of bellows folds, and a bellows cup compresses axially as vacuum is applied, so it can pick items from uneven or inclined surfaces and cushions contact at the approach. The silicone version is chosen for higher temperatures and for surfaces that must not be marked, and is common in food, packaging, and electronics handling. Cups are screwed or plugged onto a vacuum fitting and used in end-of-arm tooling for robots and pick-and-place units. The cup diameter for the SKH-25 code is not stated in the sources found.
