Airtac SAIF Series Standard Cylinder with Valve SAIF40X125S-06A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF40X125S-06A 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-06A
The AirTAC SAIF40X125S-06A is a double-acting ISO 15552 profile cylinder featuring an integrated 4M210-06 5/2 solenoid valve. Driven by an AC220V terminal coil drawing 3.5 VA, it delivers a Cv of 0.78 with a 14.0 mm2 orifice. Because the cylinder body rates to 1.0 MPa but the internal pilot valve limits pressure, the practical operating range for this assembled unit is 0.15-0.8 MPa. It provides 628N of push thrust and 528N of pull thrust at 0.5 MPa.
This decentralized unit switches itself from a single electrical signal, eliminating remote valves and excess plumbing. The factory default retracts the piston rod when the coil is energised, but you can reposition the valve to extend-when-energised. The manifold connects to the cylinder via O8 x O5 PU tubing, and the -S magnet enables position sensing with CMSE reed or DMSE electronic switches.

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-06A Is Used
Decentralized Assembly Stations
Eliminates the need for a remote valve island on large machines by switching locally via the integrated 4M210 valve and AC220V terminal signal.
Space-Constrained Automation
Fits into tight machinery envelopes where a separate cylinder and external valve manifold would occupy too much panel space.
Retrofit Position Feedback
The -S magnet allows direct mounting of CMSE or DMSE sensors for precise end-of-stroke detection in existing production lines.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF40X125S-06A the Right Choice?
Choose this 40mm bore when you need more force than the 32mm class (402N push at 0.5 MPa) but want a smaller footprint than the 50mm class (982N push). The self-contained 4M210-06 valve makes it ideal for space-tight machines where routing separate valve tubing is costly. The AC220V terminal entry provides IP65 protection and a 0.05s response time. Remember the 5/2 valve routes air and is not a lock; for load-holding applications, consider the SAIL series.
When replacing, verify the 125mm stroke, 1/8 cylinder port, PT thread type, and the 06 (1/8) valve port. The carbon steel rod and standard air cushions handle speeds of 30-800 mm/s. For strokes at or above 300mm, always use a guide to prevent side-load wear.
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-06A FAQ
At 0.5 MPa, this 40mm bore cylinder provides 628N of push force and 528N of pull force. The built-in 4M210-06 5/2 valve has an effective orifice of 14.0 mm2 and a Cv of 0.78.
No, the integrated 5/2 solenoid valve switches the cylinder directly from the AC220V coil signal. By factory default, the rod retracts when energised, but this can be reconfigured to extend-when-energised by repositioning the valve.
