Festo
189306
Vacuum suction cup ESS-40-SS
The Festo 189306 is a round, flat industrial suction cup component featuring a 40 mm diameter, a 3 mm nominal width, and an upward connection position enabling mounting in any orientation via an M6 vacuum connection. Operating across a pressure range of -95 kPa to 0 kPa with a 1.566 cm³ suction cup volume, it delivers a holding force of 69.6 N and a lateral force of 25 N at the nominal operating pressure of -70 kPa. This 16.3 g unit withstands ambient temperatures from -30 °C to 180 °C while maintaining a CRC 1 corrosion resistance rating and VDMA24364 Zone III LABS conformity for atmospheric air media conforming to 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.
