Oblong Suction Cup with 1.5 Bellows, 30x65 to 70x140 mm, COBC series
The COVAL COBC series high-performance suction cup range has been designed to meet the requirements of the automotive industry. The improved characteristics of the C series range optimize production tools in all spheres of activity.
• A full range of dimensions to meet every requirement.
• Non-slip cleats ensure optimum positioning on oily sheet metal.
• Structured suction cups for gripping thin sheet metal without deforming the piece.
• Ideal for automated applications.
• Specifically for use in the stamping and welding sectors.
Main advantages
• Extreme resistance to slipping.
• Gripping thin sheet metal without deforming the piece, thanks to the central cleats.
• Elastomer and glass-fibre reinforced plastic design to avoid any risk of damaging costly equipment and to facilitate recycling.
• Double tightening: 2 wrenches of 22mm and 1 hex key of 6mm or 8mm.
• Airtight fittings using sealing on all oblong 3/8 male suction cups.
The COVAL COBC series vacuum cups are made out of elastomer and fibreglass reinforced plastic.
These materials guarantee long life expectancy to COVAL's C series suction cups, high resistance to oils and heat resistance up to 100°C.
This approach helps to avoid any risk of deterioration of expensive production equipment and facilitates the recycling of suction cups.
