CONVUM SGB Balloon Hand Gripper

• New structured suction hand: one hand handles a wide range of shapes and sizes.
• Built-in vacuum ejector: easy operation—only compressed air supply is required.
• Use exhaust without waste (ECO): exhaust air inflates the rubber film like a balloon to generate gripping force.
• Conforms to uneven/curved surfaces: rubber film follows surface irregularities for difficult workpieces.
• Safety and control ports: relief valve for excess pressure; vacuum check and vacuum break ports for monitoring/release.

Q1: What is the SGB Balloon Hand used for?
A: It is designed for handling irregular workpieces by suction and grip using an inflatable rubber film that conforms to shape.

Q2: How is it different from a standard vacuum cup?
A: The rubber film inflates and conforms to uneven/curved surfaces, making it more suitable for difficult or soft workpieces.

Q3: How does the SGB work?
A: Compressed air drives the built-in vacuum ejector, and the exhaust air is routed into the rubber film to inflate like a balloon and create gripping force.

Q4: Do I need an external vacuum pump or vacuum source?
A: No. The SGB has a built-in vacuum ejector and operates with compressed air supply only.

Q5: What sizes are available, and how do I choose?
A: Sizes are Φ10/20/30/40 (SGB-10/20/30/40). Choose based on contact area, weight, and shape, then validate by real testing.

Q6: What rubber film materials are available?
A: Silicone (S4), NBR (N4), and metal-containing silicone (SM) for metal-detection requirements; temperature range depends on material.

Q7: How can I check vacuum and release the workpiece?
A: Use the vacuum pressure check port for monitoring, and apply vacuum break air for quick release.

Q8: What maintenance parts are available?
A: Replacement parts include rubber film, spring band sets, cushions/filters and related service parts for maintenance.
