VBU Silicone Vacuum Suction Cups & Fittings

VBU cup, fitting and specification-label checks

The VBU listing contains red silicone cups, separately selected fittings and VBU35S/VBU45S configurations. Check which item the option actually supplies.

High Specification and Premium Specification are listing labels, not numerical temperature, stroke or payload ratings. Ask for the exact technical difference before treating those variants as equivalent or as an upgrade.

Applications and Suitable Workpieces

VBU Silicone Vacuum Suction Cups & Fittings: Bellows suction cups provide vertical stroke, damping and contour adaptation for parts with height variation, curvature or sensitive surfaces.

Recommended applications

• Curved or slightly uneven plastic parts, cartons, packaged goods, formed panels, glass and general industrial components.
• Mold unloading, machine tending, sorting, assembly and robotic pick-and-place where gentle contact is required.
• Multiple-cup grippers handling parts with small differences in height or position.

Model and selection notes

• VBU35, VBU45 and VBU55 identify cup size. Cup-only, high-specification and G1/8 or G1/4 fitting variants must be matched by full code.
• More bellows layers provide greater stroke and height compensation but can allow more lateral movement; select the profile for the required stability.
• Use the exact model dimensions and thread configuration shown in the product image when matching an existing holder.
• Holding force depends on sealing area, vacuum level, surface condition, acceleration and safety factor; test the actual workpiece.
