The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF40X125S-06E is a genuine double-acting ISO 15552 cylinder with a Ø40mm bore, 125mm stroke and a built-in 4M210-06 5/2 solenoid valve — it switches itself from one coil signal, so no separate remote valve or extra plumbing is needed.
The AirTAC SAIF40X125S-06E is a double-acting ISO 15552 profile cylinder featuring an integrated 4M210-06 5/2 solenoid valve. Driven by an AC24V terminal coil drawing 3.5 VA, it delivers 628 N of push force at 0.5 MPa. The cylinder body rates to 1.0 MPa, but because the built-in valve operates at 0.15-0.8 MPa, the practical working range for this assembled unit is 0.15-0.8 MPa. A magnet is included (-S) for CMSE reed and DMSE electronic sensors.
By switching itself from one coil signal, this unit eliminates remote valves and excess tubing, making it ideal for decentralized stations across large machines. The manifold connects to the cylinder via O8 x O5 PU tubing, while the valve uses a 1/8" port and the cylinder port is 1/4". Factory-set to retract when energised, the valve can be repositioned to extend on signal. It responds in 0.05 s and carries an IP65 rating.

The cylinder rates to 1.0 MPa but the built-in valve operates 0.15–0.8 MPa, so run the assembled SAIF at 0.15–0.8 MPa. Default: rod retracts when the coil is energised (reconfigurable to extend). Specs follow the official AirTAC SAIF datasheet. Port options: PT / G.

Sized within the valve's 0.15–0.8 MPa range. Actual usable force is lower than theoretical due to friction and back-pressure.

SAIF does not hold its load without air — the valve routes air, it is not a lock. For load-holding use a SAIL (lock) or BSAI (clamp-lock).
Perfect for distributing actuation points across a large machine without routing long valve tubing back to a central manifold.
The integrated valve saves valuable panel and footprint space in tight machinery where a separate valve would not fit.
The -S magnet enables precise end-of-stroke detection using CMSE reed or DMSE electronic switches for confirmations.
Choose this 40 mm bore when a 32 mm bore (402 N push at 0.5 MPa) is underpowered, but a 50 mm bore (982 N) is physically excessive. The self-valved SAIF architecture is superior to a separate cylinder and remote valve when panel space is tight and running air tubing across a large machine is costly. This specific configuration uses an AC24V terminal entry coil with PT tapered threads.
For load-holding applications, note that the 5/2 valve routes air but does not lock the piston; refer to the SAIL series for pneumatic locking. When ordering a replacement, match the 40 mm bore, 125 mm stroke, 1/8" valve port, AC24V voltage, terminal entry, PT threads, and the -S magnet. Stroke is 125 mm, so standard mounting is fine without auxiliary guides.
Quick checklist
At 0.5 MPa, this 40 mm bore cylinder provides 628 N of push force and 528 N of pull force. The integrated 4M210-06 valve has an effective area of 14.0 mm2 (Cv 0.78) and a maximum frequency of 5 cycles per second.
No, it features a built-in 4M210 5/2 solenoid valve driven by an AC24V terminal coil. By default, the piston rod retracts when the coil is energised, but the valve can be repositioned to extend-when-energised if needed.
