Airtac SAIF Series Standard Cylinder with Valve SAIF40X125S-06C
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF40X125S-06C is a genuine double-acting ISO 15552 cylinder with a Ø40mm bore, 125mm 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 SAIF40X125S-06C
The AirTAC SAIF40X125S-06C is a double-acting ISO 15552 profile cylinder featuring an integrated 4M210-06 5/2 solenoid valve. Driven by an AC110V terminal coil drawing 3.5 VA, it eliminates the need for a remote valve island. The built-in valve has an effective area of 14.0 mm2 (Cv 0.78) and switches at up to 5 cycles per second. Because the valve operates at 0.15-0.8 MPa, this defines the practical working pressure for the assembled unit, even though the cylinder body itself rates to 1.0 MPa.
At 0.5 MPa it delivers 628 N of push force and 528 N of pull force. The manifold connects to the cylinder via O8 x O5 PU tubing, and the unit includes a magnet (-S) for direct mounting of CMSE reed or DMSE electronic sensors. From the factory, the piston rod retracts when the coil is energised, but you can reposition the valve to extend-when-energised. This self-contained design drastically cuts plumbing and panel space for 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 SAIF40X125S-06C Is Used
Decentralized Assembly Stations
Eliminates remote valve plumbing by switching locally via the AC110V coil, freeing up panel space across large automated production lines.
Compact Clamping Fixtures
Delivers 628 N of push force at 0.5 MPa in a tight ISO 15552 envelope, ideal for holding parts securely during machining operations.
Machine Retrofits
Simplifies electrical upgrades by using a terminal entry coil, allowing direct wiring to existing control systems without extensive rewiring.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF40X125S-06C the Right Choice?
Choose this 40 mm bore when you need more thrust than a 32 mm bore (which provides 402 N push at 0.5 MPa) but want a smaller footprint than a 50 mm bore. The SAIF format is optimal for space-tight machines where running separate valve tubing back to a central manifold is costly or impractical. The AC110V terminal connection suits standard factory control panels, and the PT1/8 valve port matches the cylinder port. For stroke lengths at or above 300 mm, always use a guide to prevent side-loading and premature seal wear.
When ordering a replacement, confirm the 125 mm stroke, 4M210-06 valve, AC110V terminal coil, PT thread type, and the -S magnet. Note that the 5/2 valve routes air to move the cylinder but does not lock the load; if you need true load holding, select an AirTAC SAIL locking cylinder instead.
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 SAIF40X125S-06C FAQ
At 0.5 MPa, this 40 mm bore cylinder generates 628 N of push force and 528 N of pull force. The integrated 4M210-06 valve has a 14.0 mm2 effective area (Cv 0.78) and supports a maximum frequency of 5 cycles per second.
No, it has a built-in 5/2 valve that operates on AC110V. By factory default, the rod retracts when the coil is energised, but this can be reconfigured to extend-when-energised by repositioning the valve. The valve holds its position via pilot pressure, not a spring.
