CONVUM PC 3-Bellows Suction Cups

• 3-bellows structure: supports level compensation and improved conformity for height variation.
• Wide pad diameter range: Φ3, Φ3.5, Φ5, Φ7, Φ10, Φ15, Φ18, Φ20, Φ30, Φ40, Φ60, Φ90.
• Material options available: NBR and silicone options by model.
• Multiple fittings/ports available: fixed and spring fitting lineups with top/side port options by model tables.
• Clear selection structure: select by pad diameter × stroke × material × fitting/port using the model tables.

Stroke, fittings, and port options vary by configuration. The table below provides a selection summary; for complete model details, please refer to the catalog tables.

Q1: What is PC Series designed for?
A: Applications requiring level compensation and better conformity, especially with height variation or slight surface irregularities.

Q2: What is the key benefit of 3 bellows?
A: Better stroke compensation and conformity compared with fewer-bellows designs, helping improve suction stability.

Q3: How do I choose the right pad diameter?
A: Start with the available effective contact area and leakage tendency, then select a pad diameter that provides sufficient contact area. Finally, confirm cycle time and suction stability under actual conditions.

Q4: What material options are available?
A: NBR and silicone options are available by model.

Q5: How do I choose stroke?
A: Choose based on height variation, allowed stroke, and cycle needs; the catalog provides diameter × stroke tables.

Q6: What fittings/port directions are available?
A: Fixed and spring fitting lineups are available with top/side port options depending on the model tables.

Q7: What's the fastest way to select a model?
A: Confirm pad diameter → stroke → material → port/fitting, then match the model using the catalog tables.

Q8: What should I check before final selection?
A: For rough/porous surfaces or high leakage, increase contact area or adjust material and validate stability by actual tests.
