Festo
194121
Flat cylinder DZF-1/2"-8"-A-P-A
The Festo 194121 is a double-acting industrial component featuring an 8-inch stroke and a 1/2-inch piston diameter with an oval piston providing protection against torsion and a maximum angle of rotation of plus or minus 2.5 degrees. It operates on compressed air as per ISO 8573-1:2010 [7:4:4] within an operating pressure range of 0.16 MPa to 1 MPa and an ambient temperature range of -20 °C to 80 °C, incorporating elastic cushioning rings at both ends and aluminum covers with a CRC 2 moderate corrosion stress rating. At 6 bar, it delivers a theoretical retracting force of 51 N and an advancing force of 68 N, utilizing 10-32 UNF-2B pneumatic connections and supporting oil lubrication for operation.

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.
