CONVUM PK2B High-Durability Bellows Vacuum Pads

• Bellows structure design: The bellows structure helps the pad follow the workpiece surface more easily and also makes it easier to adjust position and angle in actual equipment setups.
• Better conformity to curved surfaces: Compared with the flat type, the bellows design is better suited for curved or uneven workpiece surfaces and helps improve contact during pickup.
• Optional mesh filter: A mesh filter can be selected based on actual handling conditions so the pad setup better matches on-site requirements.
• Integrated thread design: The pad and thread are bonded into an integrated structure to help reduce the risk of loosening or separation during use.
• High-durability material: Thermoplastic polyurethane elastomer provides strong wear resistance, oil resistance, and ozone resistance for handling press-formed and metal workpieces.

Q1: What is the PK2B high-durability bellows vacuum pad?
A: PK2B Series is CONVUM's high-durability bellows vacuum pad for press-formed parts and metal workpiece handling. Its bellows structure helps the pad follow the workpiece surface more easily, especially in applications that need better conformity to curved surfaces.

Q2: What is the difference between PK2B and the PK2 flat vacuum pad?
A: PK2B uses a bellows structure, so it can follow workpiece angles and curved surfaces more easily than the flat type. PK2 is the flat version and fits a different contact style.

Q3: Why is PK2B suitable for curved workpieces?
A: The bellows structure helps the pad conform more easily to surface angles and curved profiles, making it a better fit for formed workpieces with non-flat surfaces.

Q4: What workpieces is the PK2B vacuum pad suitable for?
A: PK2B is suitable for press-formed parts, metal sheets, and other workpieces that need better conformity to curved surfaces during vacuum handling. It may also be considered for oily surfaces depending on actual conditions.

Q5: What sizes are available in the PK2B Series?
A: Available sizes are Φ10, Φ20, Φ30, Φ40, Φ50, Φ60, Φ80, Φ100, Φ120, and Φ150, so the size can be selected based on workpiece dimensions and contact conditions.

Q6: What are the material and basic specifications of PK2B?
A: The material is thermoplastic polyurethane elastomer with material symbol T, hardness A 85, semitransparent pink color, and an operating temperature range of -10 to 70°C. For sizes Φ60 and above, the insert material is polyamide.

Q7: What do the mesh filter and integrated thread design do on PK2B?
A: PK2B can be configured with an optional mesh filter to better match actual handling needs. The pad and thread are also bonded into an integrated structure to help reduce the risk of loosening or drop-off during use.

Q8: What should be checked before selecting a PK2B vacuum pad?
A: It is recommended to confirm the workpiece size, surface curvature, whether oil film is present, the required pad diameter, and whether a mesh filter or specific mounting method is needed so the setup matches the actual handling conditions.
