Custom Vacuum rubber suction cup with screw

A rubber suction cup with screw attachment needs the mounting axis aligned so the cup can meet its contact surface evenly. A secure screw connection can still pull the rim to one side if the bracket or receiving feature is angled. The flexible contact and rigid attachment should be developed together.

Custom dimensions, compound, hardness and color can follow the application. Define the thread engagement and available clearance without allowing the screw to create unintended contact beneath the cup. Select the rubber for the actual surface and environmental conditions.

During fitting, support the attachment through the intended fastening method rather than twisting the cup rim. Check contact after tightening and evaluate holding behavior using representative loads, directions and surface conditions. No general capacity follows from the screw size alone.

During maintenance, inspect the mounting connection and suction face separately. Loosening at the hardware may tilt the cup, while dirt or a nick at the rim affects the surface interface. Correct the relevant cause before reuse and store spare cups without bending their contact edges.

Material options

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

Hardness selection

Solid rubber options: 30–90 Shore A. The flexible contact and rigid attachment should be developed together.

Custom geometry

Define the thread engagement and available clearance without allowing the screw to create unintended contact beneath the cup.

Fit evaluation

Check contact after tightening and evaluate holding behavior using representative loads, directions and surface conditions.

Color & OEM

Custom colors; OEM markings outside the suction contact face.
