Name: Festo 8149449 Round cylinder DSNU-40- -F1A-
Brand: Festo

Round cylinder DSNU-40- -F1A-

The Festo 8149449 is a double-acting industrial component featuring a 40 mm piston diameter, an adjustable stroke length from 1 mm to 500 mm, and an M12x1.25 piston rod thread. Operating on compressed air per ISO 8573-1:2010 [7:4:4] within a pressure range of 1 bar to 10 bar, this unit delivers a theoretical retracting force of 633.3 N at 6 bar and incorporates adjustable pneumatic end-position cushioning alongside elastic cushioning rings. The assembly operates in any mounting position across an ambient temperature range of -20 °C to 80 °C, supports position sensing via proximity switch, and complies with VDMA24364-B1/B2-L LABS conformity with reduced copper, zinc, and nickel values suitable for battery production.

Why 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.

Engineering context

Identification and RFQ Guidance

Confirm the exact configuration

Use the manufacturer part number and model code—not appearance alone. Connection, size, material, voltage, pressure, seal, and control options can differ within the same product family.

What to include in your RFQ

Provide quantity, delivery country and ZIP/postal code, required condition, target date, and photographs of the existing nameplate when available.
