Festo
16257
Flat cylinder DZH-1 1/4"- -PPV-A
The Festo 16257 is a double-acting industrial component featuring a 1 1/4" piston diameter, an adjustable stroke ranging from 0.04 in to 40 in, and an oval piston providing torsion protection with a maximum rotation angle of +/- 1.7 deg and 1 Nm max torque. It operates within a pressure range of 0.06 MPa to 1 MPa (0.6 bar to 10 bar) using compressed air according to ISO 8573-1:2010 [7:4:4], delivers a theoretical force of 415 N retracting and 483 N advancing at 6 bar, and includes adjustable pneumatic cushioning at both ends with a 19 mm cushioning length. Built with a CRC 2 moderate corrosion stress rating and VDMA24364-B2-L LABS conformity, this unit functions in any mounting position across an ambient temperature range of -20 °C to 80 °C, supports position sensing via proximity sensor, and has an additional weight of 30 g per 10 mm stroke.

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.
