VB Series Polyurethane Vacuum Suction Cups & Fittings

Applications and Suitable Workpieces

VB Series Polyurethane 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

• VB20PU through VB50PU and VBU35PU identify cup geometry and size. Threaded and side-port fittings are separate mounting configurations.
• 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.
