Airtac SAIF Series Standard Cylinder with Valve SAIF40X175S-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF40X175S-08A is a genuine double-acting ISO 15552 cylinder with a Ø40mm bore, 175mm 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 SAIF40X175S-08A
The AirTAC SAIF40X175S-08A is a double-acting ISO 15552 profile cylinder equipped with a built-in 4M210-08 5/2 solenoid valve, delivering a Cv of 0.89 and a 16.0 mm2 effective area. Driven by an AC220V terminal entry coil that consumes 3.5 VA, it activates in 0.05 seconds. The integrated valve routes air through an O8 x O5 PU tube to the cylinder, meaning one electrical signal directly controls the motion without remote plumbing. Because the valve operates at 0.15-0.8 MPa, this defines the practical working pressure range for the assembled unit, even though the cylinder body rates to 1.0 MPa.
This 40mm bore generates 628N of push force and 528N of pull force at 0.5 MPa. By factory default, the piston rod retracts when the coil is energised, but you can reconfigure the valve to extend-when-energised by simply repositioning it. Fitted with a magnet for position sensing, it supports AirTAC CMSE reed and DMSE electronic sensors. The carbon steel piston rod and standard PT tapered threads ensure robust, leak-free pneumatic connections across 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 SAIF40X175S-08A Is Used
Decentralized Machine Stations
Eliminates the need for long tubing runs back to a central valve island, driving local actuation directly from a single AC220V signal.
Space-Constrained Automation
The integrated 4M210 valve manifold saves valuable panel and footprint space in compact machinery where external valves cannot fit.
Retrofit and Upgrades
Ideal for upgrading existing pneumatic lines, using the O8 x O5 PU tubing to locally control motion without re-plumbing the entire factory.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF40X175S-08A the Right Choice?
Choose this self-valved SAIF unit when decentralizing automation across large machines, as it eliminates separate remote valves and reduces panel space. If your application requires less force, the 32mm neighbour bore provides 402N push at 0.5 MPa; if you need more thrust, the 50mm bore yields 982N. At a 175mm stroke, the cylinder is well within the 1200mm maximum standard stroke for this bore, but always ensure proper guide support to handle side loads. Remember that the 5/2 valve routes air but does not lock the load mechanically—use an AirTAC SAIL lock cylinder if position holding without live pressure is required. To replace this exact unit, match the 40mm bore, 175mm stroke, 1/4" valve port, AC220V terminal coil, PT thread, and -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 SAIF40X175S-08A FAQ
The 40mm bore cylinder provides 628N push and 528N pull force at 0.5 MPa. The built-in 4M210-08 valve has an effective area of 16.0 mm2 (Cv 0.89) and a maximum frequency of 5 cycles per second.
By factory default, the integrated 5/2 valve routes air so the rod retracts when the AC220V coil is energised. You can reconfigure it to extend-when-energised by repositioning the valve. No separate remote valve is needed, as the unit switches itself from one coil signal.
