Polyurethane Suction Cups

Polyurethane Suction Cups

Our durable polyurethane Suction Cups are designed for aggressive applications, offering reliable performance even in challenging conditions. These suction cups come with several key features: Single and Double Bellows Design Compensates for Height Variances in Part Picking Seals on Convex and Concave Surfaces 2.5 Bellows available in diameters from 20mm to 70mm Single Bellows up to 100mm Single and Dual Durometer Polyurethane options

Vacuforce supports machine builders, integrators and maintenance teams with application-focused vacuum and pneumatic components for industrial automation.

What Are Polyurethane Suction Cups?

Vacuum suction cups create a temporary seal against a product surface so atmospheric pressure can generate holding force when vacuum is applied. Cup diameter, shape, bellows geometry, material compound and connection style should all be selected around the actual product and machine motion.

Key Features

• Multiple cup geometries for flat, curved, uneven or flexible products
• Material options for wear resistance, temperature and application compatibility
• Compact vacuum gripping for robot and machine automation
• Replacement cup and fitting configurations available across multiple sizes
• Suitable for decentralized or centralized vacuum systems depending on the machine design

Typical Applications

• Robotic pick and place
• Packaging and case handling
• Sheet and panel handling
• Plastic component handling
• Glass and metal handling where the selected cup is appropriate
• General industrial automation

Selection Guidance

Select a suction cup by product surface, cup diameter, required lifting force, load orientation, acceleration, cycle time, vacuum level and compound compatibility. Bellows cups add compliance and height compensation, while flat cups generally provide lower internal volume and fast response.

Flat vs. Bellows Cups

Flat cups are generally preferred for stable, relatively flat surfaces and fast cycling. Bellows cups add compliance, angle accommodation and height compensation where product position varies.

Why Use This Product Family?

Vacuum suction cups create a temporary seal against a product surface so atmospheric pressure can generate holding force when vacuum is applied. Cup diameter, shape, bellows geometry, material compound and connection style should all be selected around the actual product and machine motion. Selecting the correct configuration can simplify machine integration, improve serviceability and provide more consistent application performance.
