Airtac SAIF Series Standard Cylinder with Valve SAIF40X350S-06B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF40X350S-06B is a genuine double-acting ISO 15552 cylinder with a Ø40mm bore, 350mm 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 SAIF40X350S-06B
The AirTAC SAIF40X350S-06B is a double-acting profile cylinder with a built-in 4M210-06 5/2 solenoid valve, delivering a 16.0 mm2 effective area (Cv 0.89). It features a carbon steel rod, a PT 1/4 cylinder port, and includes a magnet (-S) for CMSE reed and DMSE electronic sensors. Driven by a DC24V terminal entry coil drawing 3.0 W, it activates in 0.05 s. The integrated valve routes air internally via PU tubing (O8 x O5), meaning one electrical signal controls the actuator directly for decentralized installations.
Although the cylinder body rates to 1.0 MPa, the practical SAIF operating range is 0.15-0.8 MPa because the internal pilot valve limits the assembly. At 0.5 MPa this 40 mm bore generates 628 N of push force and 528 N of pull force. The factory setting retracts the rod when the coil is energised, but you can reposition the valve to extend-when-energised. The 5/2 spool holds position via pilot pressure, not a spring, but it will not lock a load without live air.

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 SAIF40X350S-06B Is Used
Decentralized Assembly Lines
Eliminates the need for a remote valve island, allowing independent control of multiple stations across a large factory floor using a single DC24V signal.
Space-Constrained Mechanisms
The built-in 4M210 valve and manifold block reduce external plumbing, fitting a 628N thrust actuator into tight machine frames where routing air lines is difficult.
Retrofit Automation Upgrades
Ideal for upgrading older machines by adding localized pneumatic control without extensive rewiring or installing new air manifolds, leveraging the 0.05s coil response.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF40X350S-06B the Right Choice?
Choose this self-valved SAIF over a plain SAI cylinder with remote plumbing when you need to save panel space and cut tubing runs across a large machine. If you need more thrust, stepping up to the 50 mm bore yields 982 N push at 0.5 MPa; dropping to 32 mm gives 402 N. This 350 mm stroke exceeds 300 mm, so use a guide to prevent rod side-loading and premature seal wear. For load-holding applications, note that neither this valve nor the adjustable air cushions act as a lock—select an SAIL lock cylinder instead.
To replace this unit, match the 40 mm bore, 350 mm stroke, 4M210-06 valve (1/8 valve port), DC24V terminal coil, PT threads, and the -S magnet option. The valve operates at up to 5 cycles per second.
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 SAIF40X350S-06B FAQ
At 0.5 MPa operating pressure, the 40mm bore provides 628 N push and 528 N pull force. The built-in 4M210-06 valve has a 14.0 mm2 orifice with a Cv of 0.78.
The integrated 5/2 valve is factory-set to retract the rod when the DC24V coil is energised, but can be reconfigured to extend-when-energised. It holds position via pilot pressure, not a spring, and does not lock loads without live air pressure.
