Festo
189406
Vacuum suction cup ESS-50-CN
Engineered with a round protective bellows 3.5-fold shape, this Festo industrial component features a 50 mm suction cup diameter, 3 mm nominal width, and 17.5 mm height compensation for handling workpieces with a minimum radius of 180 mm. The unit operates within a pressure range of -95 kPa to 0 kPa, delivering a holding force of 63.4 N and a lateral force of 49 N at the nominal operating pressure of -70 kPa. Designed with an upward connection position and mounting via vacuum connection in any position, the 32.1 g assembly withstands ambient temperatures from -10 °C to 70 °C under low corrosion stress.

Request a QuoteWhy no listed price?
Industrial and obsolete parts are priced per enquiry: the final price depends on available stock, condition, quantity, and your delivery destination, so a fixed list price would be misleading. Request a quote and we confirm current pricing, lead time, and sourcing options — including hard-to-find and discontinued Festo references — within one business day.
