Festo
525978
Vacuum suction cup ESS-50-GT-G1/4-I
The Festo 525978 is a round, deep industrial component featuring a 50 mm suction cup diameter, an 8 mm height compensator, and a nominal width of 2.5 mm. It operates at a pressure range of -0.95 bar to 0 bar with a nominal operating pressure of -0.7 bar, delivering a holding force of 97 N and a lateral force of 30 N using atmospheric air based on ISO 8573-1:2010 [7:-:-]. Weighing 18 g with a reddish-brown color and 72 +/-5 Shore hardness, this part provides 11.2 cm³ of suction cup volume, VDMA24364-A1-L LABS conformity, and CRC 2 moderate corrosion stress resistance across an ambient temperature range of -10 °C to 80 °C. Mountable in any position via the G1/4 vacuum connection, it accommodates a minimum workpiece radius of 40 mm.
