Vacuum cup is a pneumatic component used in industrial automation for gripping and handling objects through suction force.
A vacuum cup is a flexible, typically bellows-shaped component made from elastomeric materials that creates a vacuum seal when pressed against an object's surface. It functions as the interface between a vacuum system and the workpiece in material handling applications, enabling secure gripping without mechanical clamps. The cup deforms to match surface contours, creating an airtight seal that allows atmospheric pressure to hold the object when internal air is evacuated.

Vacuum cups work best on smooth, non-porous surfaces like glass, metal, plastic, and coated materials. They can handle slightly curved surfaces but struggle with highly porous, rough, or oily surfaces without special adaptations.
Calculate based on object weight, safety factor (typically 2-4x), vacuum level, and surface conditions. Formula: Cup diameter = √(4 × Weight × Safety Factor / (π × Vacuum Pressure × Friction Coefficient)).
Regular inspection for wear, cracks, or contamination; cleaning of sealing surfaces; replacement when hardness increases by 10 Shore points or visible damage occurs; checking vacuum lines for leaks.
