Material: NBR nitrile, polyamide insert
CVL suction cups are made of NBR nitrile 55 Shore A, with a PA polyamide 6.6 insert that reduces weight and an NBR nitrile O-ring.
Magnetic suction cups in polyurethane of 60° hardness are also available.
Reading the lifting force
The lifting force of CVL cups is measured at 65% on dry, smooth, flat sheet, with no safety factor: apply your own factor for the sheet condition and the line's accelerations.
For magnetic suction cups, the force F is given in newtons at −0.6 bar of vacuum.
Shape and mounting
Suction cups come round or oblong, flat or bellows, with a male or female 3/8G thread. They mount on the spring-axis supports of the grippers (G 3/8 thread on the cup side).
