Custom made bellow vacuum silicone rubber suction cups

A silicone rubber suction cup with bellows combines a contact face with a folded body. The bellows geometry needs room to move between the attachment and the surface. Its dimensions and material should be developed around the actual equipment arrangement rather than only the diameter of the contact rim.

Define the shortest and longest positions encountered during use. The folds should not be crushed against adjacent hardware or stretched beyond the movement established for the design. The upper connection also needs to hold the cup in its intended alignment so that the contact face can seat naturally.

Evaluate the complete setup on the actual surface and under its intended loading. Surface texture, curvature, contamination, and the direction of force affect the connection. Keep the item controlled while establishing the arrangement. Clean the rim before placement and release it through the intended method for removal. During maintenance, inspect the fold roots as well as the thin contact edge, since damage in the body may be hidden when the cup is compressed.
