Airtac SAIF Series Standard Cylinder with Valve SAIF40X700-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF40X700-08B is a genuine double-acting ISO 15552 cylinder with a Ø40mm bore, 700mm stroke and a built-in 4M210-08 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 SAIF40X700-08B
The AirTAC SAIF40X700-08B is a double-acting ISO 15552 profile cylinder featuring an integrated 4M210-08 5/2 solenoid valve with a 16.0 mm2 orifice (Cv 0.89). Driven by a DC24V terminal entry coil drawing 3.0 W, it activates in 0.05 seconds or less. Because the cylinder body rates to 1.0 MPa but the internal pilot valve operates at 0.15-0.8 MPa, the practical working range for this assembled unit is 0.15-0.8 MPa. It delivers 628N of push force at 0.5 MPa and 1130N at 0.9 MPa.
By self-switching from a single coil signal, it eliminates the need for a separate remote valve, drastically reducing panel space and plumbing. The manifold connects to the cylinder via an O8 x O5 PU tube, and the valve PT1/4 port is distinct from the cylinder PT1/4 port. Factory set to retract the rod when energised, the valve can be repositioned to extend on signal. It suits decentralized stations across large machines perfectly.

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 SAIF40X700-08B Is Used
Decentralized Assembly Lines
Eliminates remote valve banks by switching locally via the built-in 4M210 valve, cutting tubing runs across large factory layouts.
Space-Constrained Machinery
Fits tight machine envelopes where a separate valve manifold would not fit, driving 1130N of push force at 0.9 MPa.
Wiring-Retrofit Stations
Simplifies electrical upgrades by routing a single DC24V terminal coil signal instead of complex pneumatic control lines.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF40X700-08B the Right Choice?
Select this 40mm bore model when an application requires 528N of pull force at 0.5 MPa; stepping down to a 32mm bore drops the push force to 402N, while a 50mm bore raises it to 982N. A self-valved SAIF excels over a standard SAI cylinder with remote valve when floor space is tight and running pneumatic tubing is costly. For load-holding applications, note that the 5/2 valve routes air but does not lock the load; consider an AirTAC SAIL lock cylinder instead. When ordering replacements, verify the 700mm stroke, PT1/4 port threads, DC24V voltage, terminal entry, and the absence of a magnet (-S). Because the stroke is 700mm, ensure proper guide support to prevent rod side-load and binding.
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 SAIF40X700-08B FAQ
At 0.5 MPa it provides 628N of push force and 528N of pull force. At 0.9 MPa the push force reaches 1130N.
Yes, the factory setting retracts the rod when the DC24V coil is energised, but repositioning the 4M210 valve on the manifold block changes it to extend-when-energised.
