Airtac SAIF Series Standard Cylinder with Valve SAIF40X50S-06A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF40X50S-06A is a genuine double-acting ISO 15552 cylinder with a Ø40mm bore, 50mm 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 SAIF40X50S-06A
The AirTAC SAIF40X50S-06A is a double-acting ISO 15552 profile cylinder equipped with a built-in 4M210-06 5/2 solenoid valve, providing a Cv of 0.78. It features a 40mm bore, a 50mm stroke, and a carbon steel piston rod. Driven by an AC220V terminal connection coil drawing 3.5 VA, it activates in 0.05s. Because the valve operates at 0.15-0.8 MPa, the practical working range for this assembled SAIF unit is 0.15-0.8 MPa, despite the cylinder body rating to 1.0 MPa. At 0.5 MPa it delivers 628N push force.
This self-switching unit eliminates the need for a remote valve, drastically reducing tubing and panel space for decentralized machine stations. The manifold links the valve to the cylinder using an O8xO5 PU tube, meaning the 1/8" valve port differs from the cylinder's 1/4" port. Factory set to retract the rod when energised, the 5/2 valve can be repositioned to extend on signal instead. It includes a magnet for CMSE reed and DMSE electronic sensors.

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)

| 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 SAIF40X50S-06A Is Used
Decentralized Stations
Perfect for large machines needing decentralized control, driving the 40mm bore directly from a single AC220V signal without a remote valve bank.
Space-Tight Handling
The integrated 4M210-06 valve and manifold block save panel space, fitting neatly into compact assemblies where external plumbing is impossible.
Retrofit Automation
Ideal for upgrading older lines where running new valve tubing is costly, providing a self-contained 5/2 switching solution with a 1/8" port.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF40X50S-06A the Right Choice?
Select this 40mm bore when you need around 628N of push force at 0.5 MPa; stepping down to a 32mm bore yields 402N, while a 50mm bore provides 982N. A self-valved SAIF is ideal when fitting a separate valve and running tubing is too costly or space-prohibitive. To replace this unit, match the 40mm bore, 50mm stroke, 1/8" valve port, AC220V voltage, terminal entry, PT thread, and the -S magnet. Note that the 5/2 valve routes air and is not a lock; it cannot hold a load without live pressure, so consider a SAIL lock cylinder if load-holding is required.
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 SAIF40X50S-06A FAQ
The 40mm bore generates 628N push and 528N pull force at 0.5 MPa. The built-in 4M210-06 5/2 valve has an effective area of 14.0 mm2 (Cv 0.78) and a max frequency of 5 cycles/sec.
The 5/2 valve routes air but does not lock the load without live pressure. Factory set to retract the rod when the AC220V coil energises, the valve can be repositioned to extend-when-energised, eliminating the need for a separate remote valve.
