Round cylinder DSNU-S-12-125-P-A-MQ

The Festo part number 5211908 is a double-acting industrial component featuring a 12 mm piston diameter and a 125 mm stroke with an M6 piston rod thread. This structural design incorporates elastic cushioning rings at both ends, accommodates any mounting position, and enables position sensing via proximity switch for operating pressures ranging from 0.15 MPa to 1 MPa (1.5 bar to 10 bar). It operates using compressed air as per ISO 8573-1:2010 [7:4:4], with oil lubrication possible and required for continued use, while delivering a theoretical force of 67.9 N advancing and 50.9 N retracting at 6 bar.

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.

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.
