CONVUM PJ 2-Bellows Vacuum Pads

• Low-profile 2-bellows design: thin lip improves conformity on angled/curved surfaces.
• For tight spaces: suitable when there is no space for attaching spring type fittings.
• Wide size range: cup sizes cover Φ2 to Φ80.
• Material options available: NBR, silicone, urethane, fluorine rubber, conductive NBR, conductive silicone.
• Various fitting options: multiple fitting styles and port directions (top/side) for different setups.

Q1: What workpieces are PJ pads designed for?
A: Angled or spherical/curved workpieces where better conformity is required.

Q2: Why is PJ suitable for tight spaces?
A: It is positioned for cases where spring type fittings cannot be used due to space limits.

Q3: What cup sizes are available?
A: Sizes cover Φ2 to Φ80 (per catalog size codes).

Q4: What do material codes N/S/U/F/NE/SE mean?
A: NBR, silicone, urethane, fluorine rubber, conductive NBR, conductive silicone.

Q5: When should I use conductive materials (NE/SE)?
A: When ESD control is required, evaluate conductive materials and ensure proper grounding.

Q6: What port directions are available?
A: The catalog provides top-port and side-port combinations depending on model/fitting.

Q7: How do I choose a fitting style?
A: Select based on mounting space, port direction, and whether compensation is needed, referring to the catalog model tables.

Q8: What should I check before selecting a size/material?
A: For high leakage or rough/porous surfaces, evaluate required holding force and validate stability by actual tests.
