Festo
15891
Round cylinder EG-6-5-PK-3
The Festo 15891 is a single-acting industrial component featuring a 6 mm piston diameter, a 5 mm stroke, and an M3 piston rod thread with an external thread end. Operating on compressed air as per ISO 8573-1:2010 [7:-:-] within a pressure range of 3 bar to 7 bar, this 19 g piston rod cylinder delivers a theoretical advancing force of 11.8 N at 6 bar alongside a spring return force ranging from 4.1 N to 5.2 N. Designed with non-adjustable cushioning at one end, no position sensing, and low corrosion stress resistance (CRC 1), the unit mounts via locknut in any position.

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.
