Airtac SAIF Series Standard Cylinder with Valve SAIF40X80S-06E
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF40X80S-06E is a genuine double-acting ISO 15552 cylinder with a Ø40mm bore, 80mm 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.

About the Airtac SAIF Series Standard Cylinder with Valve SAIF40X80S-06E
The AirTAC SAIF40X80S-06E is a double-acting ISO 15552 profile cylinder featuring an integrated 4M210-06 5/2 solenoid valve. This specific SKU specifies an AC24V terminal coil and includes a magnet for CMSE reed and DMSE electronic sensors. The built-in valve has an effective area of 14.0 mm2 (Cv 0.78) and connects to the cylinder bore via an O8 x O5 PU tube. Because the cylinder body rates to 1.0 MPa but the internal piloted valve operates at 0.15-0.8 MPa, the practical working range for this assembled unit is 0.15-0.8 MPa.
By default, the piston rod retracts when the coil is energised, but you can reconfigure it to extend-when-energised by repositioning the valve. This self-switching design eliminates the need for a separate remote valve, saving panel space and making it ideal for decentralized stations across large machines. In the 40mm bore class, it delivers 628N of push force at 0.5 MPa and 879N at 0.7 MPa.

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.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
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).
Where the Airtac SAIF Series Standard Cylinder with Valve SAIF40X80S-06E Is Used
Decentralized Machine Stations
Ideal for large equipment where running separate valve tubing is costly, this self-valved cylinder drives directly from one AC24V coil signal.
Compact Assembly Automation
Saves panel space by integrating the 4M210 valve directly on the profile body, delivering 628N of push force for compact clamping and positioning.
Sensor-Ready Conveying
The included -S magnet works with DMSE electronic sensors for precise end-of-stroke detection on short-stroke material transfer gates.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF40X80S-06E the Right Choice?
Choose this 40mm bore model when your application requires around 628N push force at 0.5 MPa; step down to a 32mm bore (402N push) for lighter duties, or up to a 50mm bore (982N push) if you need greater thrust. The SAIF40X80S-06E is optimal for decentralized installations where running separate valve tubing is costly or space-constrained. It carries a PT1/8 cylinder port and a 1/8 valve port. To order a replacement, match the 40mm bore, 80mm stroke, 06 valve port, AC24V voltage, terminal entry, PT thread, and -S magnet.
For stroke lengths of 300mm or more, add an external guide to manage side loads. Note that the built-in 5/2 valve routes air but does not lock the load mechanically; for position holding, consider the SAIL lock or BSAI clamp-lock series instead.
Quick checklist
- ✓ Force at 0.15–0.8 MPa
- ✓ Coil voltage matches panel
- ✓ Terminal vs grommet entry
- ✓ Retract- or extend-when-energised
- ✓ Load-holding → SAIL / BSAI
Airtac SAIF Series Standard Cylinder with Valve SAIF40X80S-06E FAQ
The 40mm bore generates 628N of push force and 528N of pull force at 0.5 MPa. The built-in 4M210-06 valve provides an effective area of 14.0 mm2 (Cv 0.78) with a maximum frequency of 5 cycles per second.
The integrated 5/2 valve eliminates the need for a separate remote valve, reducing plumbing and panel space for decentralized installations. The factory setting retracts the rod when the AC24V coil is energised, but it can be reconfigured to extend-when-energised by repositioning the valve.
