Festo
158521
Compact cylinder DMM-20-5-P-A
The Festo 158521 is a double-acting industrial component featuring a 20 mm piston diameter, a 5 mm stroke, and a single-ended piston rod with a profile barrel and brass cover. Designed for an operating medium of compressed air in accordance with ISO8573-1:2010 [7:4:4] within a 1 to 10 bar working pressure range, it delivers a theoretical force of 188 N on the advance stroke and 158 N on the return stroke at 6 bar. This unit incorporates flexible cushioning rings or plates at both ends (P cushioning), position detection for a proximity sensor, and moderate corrosion resistance classification CRC 2 across an ambient temperature range of -20 to 80 °C.

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.
