Foam Rings & CLK Vacuum Suction Cup Assemblies
Replacement foam rings and complete CLK vacuum suction cup assemblies in one model list.
- Foam ring labels state outer diameter, inner diameter and thickness in millimeters
- CLK assembly models include G1/8 or G3/8 connection designations
- Each model includes a corresponding dimensional drawing
Select the exact model and confirm all dimensions shown in its image before ordering.
Applications and Suitable Workpieces
Foam Rings & CLK Vacuum Suction Cup Assemblies: Foam contact pads conform to textured, slightly uneven or mildly porous workpieces that are difficult to seal with a plain rubber lip.
Recommended applications
- Cardboard, cartons, coated or uncoated sheet material, textured plastic, wood panels, composites and other flat or slightly uneven parts.
- Robot grippers, palletizing, depalletizing, panel transfer, pick-and-place and general material-handling systems.
- Workpieces with small gaps, surface texture or height variation where the foam can bridge minor leakage paths.
Model and selection notes
- Foam-ring variants require the specified outer diameter, inner diameter and thickness; CLK variants are complete assemblies with the listed thread.
- Select the cup diameter and foam footprint according to the available contact area and required holding force.
- Single-, double- and multi-layer bodies provide progressively more stroke and height compensation; choose the model shown in the technical drawing.
- Foam wears during service and should be inspected regularly. Very porous stock may require a higher-flow vacuum source or multiple cups.
