Double Layer Suction Cup Vacuum Suction Cup

A double layer suction cup uses a shaped rubber profile at a vacuum contact point. The layered construction should be considered alongside the contact lip and mounting connection, rather than interpreted as a simple multiplication of holding capacity. Performance depends on the complete vacuum system and the surface being handled.

Check how the cup meets the target surface and how its body can deform during contact. A suitable lip needs continuous contact without being obstructed by texture, seams or debris. The vacuum connection must also match the assembly so air leakage at the mount does not undermine the seal at the workpiece.

Evaluate the cup under the intended movement, orientation and vacuum conditions before assigning it a handling duty. Sideways forces and acceleration can affect retention differently from a stationary test. Inspect both contact edges and the transitions between layers for damage during maintenance. Replace a worn cup rather than compensating for a damaged lip by assuming more vacuum will restore the original contact geometry.

Material options

Rubber compound options, customized alongside the profile and contact conditions.

Hardness selection

Solid rubber options: 30–90 Shore A. Check how the cup meets the target surface and how its body can deform during contact.
