Product Overview

A black suction cup with an internal nut provides a molded suction-contact body and a threaded mounting interface. The 80 mm size designation needs to be considered with the cup's full profile and the actual contact surface. The nut dimensions are a separate part of the mounting selection.

Check the thread, engagement length, and holder geometry before assembly. The fastener should secure the cup without bottoming out incorrectly or distorting the suction face. The holder needs to keep the cup aligned with the workpiece rather than applying a persistent sideways load at the attachment.

The suction lip must meet a suitable continuous surface. Texture, curvature, seams, and contamination can affect contact even when there is enough visible area for the nominal cup size. Select the compound for the workpiece temperature and substances involved. Evaluate the complete system under its actual vacuum, load, orientation, and movement conditions; the 80 mm designation and internal nut do not establish a lifting capacity. Inspect both the lip and the threaded attachment during maintenance. Replace damaged rubber and correct loose or misaligned hardware before returning the arrangement to operation, preserving the intended contact and mounting relationships.

Material options: Rubber compound options, customized alongside the profile and contact conditions.
Hardness selection: Solid rubber options: 30–90 Shore A. Check the thread, engagement length, and holder geometry before assembly.
Custom geometry: The nut dimensions are a separate part of the mounting selection.
Fit evaluation: The holder needs to keep the cup aligned with the workpiece rather than applying a persistent sideways load at the attachment.
Color & OEM: Custom colors; OEM markings outside the suction contact face.

Ordering this custom component

Can the shape be adjusted to my mating parts?

Yes. Show the receiving opening, contact surfaces and clearance limits. We can review the dimensions and retaining features around the intended fit.

Which details should be agreed before tooling?

Agree the critical dimensions, material, hardness, visible surfaces and sample requirements. Explain how the part is installed and which interfaces control its function.

Can a sample help define the replacement?

A sample can help explain the structure. Compare it with the assembly because wear, swelling or compression may have changed its original dimensions.

How is the quotation for this part determined?

The material, part geometry, tooling, quantity and finishing affect the quotation. Include the intended batch size and delivery destination when describing your requirements.
