SAF Nitrile Rubber Vacuum Suction Cups and Anti-Rotation Fittings

Applications and Suitable Workpieces

SAF is a robust round nitrile-rubber flat suction cup for fast, repeatable handling of smooth sheet-metal and automotive workpieces. Its structured support and sealing geometry are intended to resist lateral movement, including on lightly oily surfaces.

Recommended applications

• Thin steel sheets, aluminum sheets, smooth stamped panels and general flat metal parts.
• Automotive press-line feeders, punching-machine positioning, destacking, transfer presses and robotic loading or unloading.
• Dry or oily sheet-metal workpieces requiring short cycle times and stable positioning.
• Slightly curved panels where the flexible sealing lip can still form a complete seal.

Model and fitting notes

• SAF cup size: choose the diameter according to the available sealing area, workpiece mass and dynamic load.
• SAF30N and other NBR models: suitable where oil resistance and abrasion resistance are more important than high-temperature capability.
• FSTE anti-rotation and threaded fittings: recommended where cup orientation and repeatable positioning must be maintained; select the thread to match the machine interface.
• Use only on surfaces with a continuous, non-porous sealing path. Verify holding force on the actual dry or oily workpiece before production.
