Airtac SAIF Series Standard Cylinder with Valve SAIF40X80S-06A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF40X80S-06A 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-06A
The AirTAC SAIF40X80S-06A is a double-acting ISO 15552 profile cylinder featuring a built-in 4M210-06 5/2 solenoid valve. This integrated assembly delivers a Cv of 0.78 (14.0 mm2 orifice) and generates 628N of push force at 0.5 MPa. Equipped with a carbon steel piston rod and a -S magnet for CMSE reed and DMSE electronic sensors, it eliminates the need for remote plumbing. The unit is driven by an AC220V terminal coil drawing 3.5 VA, responding in 0.05s with an IP65 rating.
Because the cylinder body rates to 1.0 MPa but the internal pilot valve operates at 0.15-0.8 MPa, the practical working pressure for this valved unit is 0.15-0.8 MPa. The manifold connects the valve to the cylinder using O8 x O5 PU tubing, meaning the 1/8 valve port and 1/4 cylinder port are distinct. Factory-set to retract when energised, the valve can be repositioned to extend on signal, enabling fully decentralized machine stations.

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-06A Is Used
Decentralized Assembly Stations
Ideal for large machines with distributed stations, using one AC220V signal to drive the cylinder without running long valve tubing back to a central manifold.
Compact Clamping Fixtures
Provides 628N of push force at 0.5 MPa in tight spaces, using the built-in 4M210 valve to minimize the pneumatic footprint on the tooling plate.
Retrofit Automation
Perfect for upgrading existing lines where adding a separate valve island is impractical, offering self-switching operation with CMSE/DMSE sensor tracking.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF40X80S-06A the Right Choice?
Choose this 40mm bore when a 32mm cylinder (402N push at 0.5 MPa) lacks thrust, but a 50mm bore (982N at 0.5 MPa) is excessive. The self-contained SAIF design excels where routing separate valve tubing is costly or panel space is tight. Select this AC220V terminal entry configuration for standard factory power grids; the PT thread matches common local fittings. For position feedback, pair the -S magnet with CMSE or DMSE switches.
When replacing, match the 40mm bore, 80mm stroke, 1/8 valve port, AC220V voltage, terminal entry, PT thread, and -S magnet. Note that the 5/2 valve routes air but does not lock the load; for position holding under pressure loss, consider the SAIL lock series. At 80mm stroke, side-load guides are not strictly necessary but ensure rod alignment for optimal cushioning.
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-06A FAQ
The 40mm bore generates 628N push and 528N pull force at 0.5 MPa. The built-in 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 has a built-in 5/2 valve. By default, the rod retracts when the AC220V coil is energised, but it can be reconfigured to extend on signal by repositioning the valve, eliminating the need for remote plumbing.
