Festo
189341
Vacuum suction cup ESS-20-EF
The Festo industrial component, part number 189341, is a round, extra-deep suction cup with a 20 mm diameter, a 3 mm nominal width, and a 0.84 cm³ suction cup volume that accommodates a minimum workpiece radius of 30 mm. Weighing 6.4 g with a CRC rating of 1 for low corrosion stress and an ambient temperature range of -10 °C to 200 °C, this unit mounts via an M6 vacuum connection positioned at the top in any mounting position. It operates between -95 kPa and 0 kPa, delivering a holding force of 17 N and a lateral force of 15.5 N at a nominal operating pressure of -70 kPa using atmospheric air based on ISO 8573-1:2010 [7:-:-].

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.
