Description
Small-head silicone suction cups for vacuum tooling
IKSONIC small-head silicone vacuum suction cups are available in SP single-bellows, DP double-bellows and MP triple-bellows configurations. The selection also includes two SPL small-lip cup models, separate M5 mounting fittings and a custom-specification enquiry option. These are individual cup and fitting choices, not a mixed kit containing every item shown.
Match the cup’s contact diameter, overall shape and mounting socket to the workpiece and end-of-arm tooling. Cups with a similar lip diameter can have different heights and body profiles, so the model family matters as much as the size designation. The SP selection includes SP-S40 alongside the smaller sizes.
Product and selection specifications
| Item | Specification or choice |
|---|---|

| DP family | Double-bellows cups; nine model choices. |
| MP family | Triple-bellows cups; six model choices. |
| Additional cup models | SPL-2 and SPL-4, listed separately from the SP, DP and MP choices. |
| Cup mounting opening | 5 mm opening identified for this small-head range; check the complete socket and fitting geometry as well. |
| Fitting options | M5 female-thread and M5 male-thread fittings, separately selected; both drawings specify M5 × 0.8. |
| Custom configuration | Enquiry based on the required shape, dimensions and application; no fixed custom size is implied. |
31 model and configuration choices
Select the complete model and the required quantity. Silicone cups, M5 fittings and custom configurations are separate choices; specify each component needed for the assembly.
Reference dimensions are in millimetres. The table compares cup-lip diameter, overall height and upper-body diameter for each model. Confirm the selected cup and fitting dimensions before designing mating components. A cup’s overall height is not its working stroke or permissible compression.

| M5 female thread | Mounting fitting | Not applicable | Not applicable | Not applicable |
| M5 male thread | Mounting fitting | Not applicable | Not applicable | Not applicable |
| Custom specification | Custom enquiry | Not applicable | Not applicable | Not applicable |
The model list includes 28 cup choices, two fitting choices and one custom enquiry. Model-specific dimensions are not interchangeable: for example, MP–S12 is 15 mm high, while MP-S10 is 15.5 mm high. Select and confirm the actual model rather than scaling another cup’s dimensions.
M5 mounting-fitting dimensions
The female and male fittings have different lower-stem and retaining-lip diameters. An M5 thread description alone does not establish the cup-side fit. Select the fitting separately from the silicone cup and check their mating geometry together.
| Enquiry option | Thread | Hexagon across flats (mm) | Lower-stem diameter (mm) | Retaining-lip diameter (mm) | Through-bore diameter (mm) |
|---|---|---|---|---|---|
| M5 female thread | M5 × 0.8 female | 8 | 4 | 6 | 1.8 |
| M5 male thread | M5 × 0.8 male | 8 | 5 | 7 | 1.8 |
Check the thread and cup-side dimensions together. The assembled tooling height depends on the selected cup and mounting arrangement. Specify any required metal grade or surface treatment separately.
Choosing the cup and mounting arrangement
- Check the contact area. Compare the cup lip with the available sealing area on the workpiece. Edges, openings and changes in curvature should be considered when defining the required cup geometry.
- Compare the complete profile. SP, DP and MP have different bellows arrangements. Check height and surrounding clearance instead of assuming that additional bellows specify a particular travel or holding force.
- Inspect the connection. The mounting opening is only one dimension of the socket. Compare the mating stem, retaining feature and fitting orientation before choosing replacement parts.
- Specify operating requirements. Provide the workpiece surface, handling orientation, required cycle conditions and operating environment so that suitability can be assessed for the actual assembly.
- Separate components in the order. State the cup models, fitting types and quantities required. Display photographs do not define a complete tooling package.
Enquiry information
| Provide | Purpose |
|---|---|
| Complete option label and quantity | Distinguishes the cup family, size and separately selected fittings. |
| Required dimensions and mating-component details | Checks the cup lip, installed envelope, socket and retention geometry together. |
| Workpiece description and operating conditions | Defines the application rather than assuming performance from appearance. |
| Colour, material grade and documentation requirements | Defines the required material, appearance and documentation for the selected application. |
| Drawing or measurements for a custom enquiry | Defines a non-standard configuration without assigning an invented size. |
Holding force, vacuum level, temperature capability and application-specific compliance are not established by the model code or dimensions alone. For a model-specific enquiry, contact IKSONIC with the required cup and fitting details.
