Airtac SAIF Series Standard Cylinder with Valve SAIF40X400S-06B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF40X400S-06B is a genuine double-acting ISO 15552 cylinder with a Ø40mm bore, 400mm 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 SAIF40X400S-06B
The AirTAC SAIF40X400S is a double-acting ISO 15552 profile cylinder featuring an integrated 4M210-06 5/2 solenoid valve. This specific SKU is configured with a DC24V terminal electrical entry consuming 3.0 W, a PT1/8 cylinder port, and a 1/8 inch valve port. The built-in valve offers an effective area of 14.0 mm2 (Cv 0.78) and operates at 5 cycles per second. Because the valve manifold mounts directly using O8 x O5 PU tubing, it eliminates remote plumbing and is ideal for decentralized machine stations.
While the bare cylinder body rates to 1.0 MPa, the practical operating range for this assembled SAIF unit is 0.15-0.8 MPa due to the internal pilot valve limits. It delivers 628 Newtons of push force and 528 Newtons of pull force at 0.5 MPa. Factory set to retract the rod when the coil is energised, the valve can be repositioned to extend-when-energised if your logic requires it. The -S magnet option enables tracking by AirTAC CMSE reed or 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)
| 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 SAIF40X400S-06B Is Used
Decentralized Stations
Eliminates the need for a central valve bank on large machines by switching locally from one DC24V signal.
Material Handling
Provides 628N push force for diverting or gating items over a 400 mm travel without external plumbing.
Space-Tight Retrofits
Ideal for upgrading older machines where routing new pneumatic lines to a remote valve is impractical.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF40X400S-06B the Right Choice?
Choose this 40 mm bore when you need 628N thrust at 0.5 MPa; stepping up to the 50 mm bore yields 982N push force, while dropping to 32 mm provides only 402N. The 400 mm stroke is well within the 1200 mm standard maximum for this bore, but at this length you should ensure adequate side-load guidance to prevent rod seal wear. This self-valved unit excels over a separate cylinder and remote valve when panel space is tight and running tubing is costly.
Remember the 5/2 valve routes air but does not lock the load mechanically; if you need true hold without live pressure, consider the SAIL lock variant. To replace this unit exactly, match the 40x400 stroke, the 4M210-06 valve with 1/8 inch port, the DC24V terminal coil, PT thread, and the -S magnet.
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 SAIF40X400S-06B FAQ
At 0.5 MPa it provides 628N push and 528N pull force. The built-in 4M210-06 valve has a 14.0 mm2 orifice (Cv 0.78) and a maximum frequency of 5 cycles per second.
No, it switches itself via the integrated 5/2 valve driven by a DC24V terminal coil (3.0 W, IP65). Factory set to retract when energised, it can be reconfigured to extend-when-energised by repositioning the valve.
