Vacuum Cup Guides & Technical Resources

Compare silicone and NBR vacuum suction cups by temperature, oil resistance, wear, sealing behavior and application before choosing a material.

Choose vacuum cup holders by cup thread, mounting thread, port direction, tube size, stroke, height variation and workpiece sensitivity.

Select vacuum cups for cardboard, wood, foam and textured surfaces by leakage rate, cup profile, vacuum flow and handling conditions.

A practical guide to choosing vacuum cups for glass and smooth panels, covering surface protection, material, diameter, layout, monitoring and validation.

A practical guide to selecting vacuum cups for sheet metal, including oil, flatness, edges, holes, material, diameter, layout and production-speed validation.

A practical daily, weekly and monthly vacuum cup maintenance checklist for preventing leaks, slow pickup, premature wear and unplanned downtime.

Diagnose vacuum cup leaks, weak holding force, slow pickup, dropped parts and rapid wear with a practical inspection sequence.

Choose a vacuum cup by workpiece surface, profile, material, diameter, load, motion and mounting, with links to detailed BOLTTE guides and products.

A practical selection method for bag-opening cups covering film, pickup point, diameter, profile, leakage, vacuum flow, mounting and production testing.

Compare flat, single-bellows and multi-bellows vacuum cups by surface shape, height compensation, stability, response time and handling risk.

Calculate vacuum cup holding force from pressure and sealing area, apply safety factors and motion loads, then choose and validate cup diameter.
