Airtac SAIF Series Standard Cylinder with Valve SAIF32X250S-06E
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF32X250S-06E is a genuine double-acting ISO 15552 cylinder with a Ø32mm bore, 250mm 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 SAIF32X250S-06E
The AirTAC SAIF32X250S-06E is a double-acting ISO 15552 profile cylinder featuring an integrated 4M210-06 5/2 solenoid valve. Driven by an AC24V terminal coil drawing 3.5 VA, the valve delivers a Cv of 0.78 and operates at a maximum frequency of 5 cycles per second. While the cylinder body rates to 1.0 MPa, the built-in valve limits the practical working pressure to 0.15-0.8 MPa. It delivers 402N of push force at 0.5 MPa.
By default, the piston rod retracts when the coil is energised, but this can be reconfigured to extend-when-energised simply by repositioning the valve. The manifold connects to the cylinder via O8xO5 PU tubing, meaning the 1/8" valve port differs from the 1/8" cylinder port. This self-contained unit eliminates remote valves, reducing plumbing and panel space for decentralized machine stations. The -S magnet supports AirTAC CMSE reed and DMSE electronic sensors.

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 (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 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 SAIF32X250S-06E Is Used
Decentralized Stations
Ideal for large machines with multiple stations, eliminating long tubing runs by mounting the valve directly on the cylinder.
Compact Clamping
Provides 402N of push force in tight spaces where a separate valve panel would not fit, using a single AC24V signal.
Retrofit Upgrades
Simplifies machine upgrades by replacing a standard cylinder and remote valve with a self-switching unit, cutting plumbing complexity.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF32X250S-06E the Right Choice?
Choose this 32mm bore when you need 402N push force at 0.5 MPa; step up to the 40mm bore if your application requires 628N. The integrated 4M210-06 valve means you only need to run a single AC24V electrical signal and air supply to the cylinder, saving space over a traditional cylinder with a separate remote valve. For position feedback, use CMSE or DMSE sensors in the side groove. When replacing, match the 250mm stroke, 1/8" valve port, AC24V terminal coil, PT thread, and -S magnet. Because the stroke is 250mm, ensure adequate guide support to prevent side-loading on the rod. Note that the 5/2 valve routes air and does not lock the load; for holding requirements, consider the SAIL series.
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 SAIF32X250S-06E FAQ
At 0.5 MPa, this 32mm bore cylinder provides 402N of push force and 345N of pull force. The integrated 4M210-06 5/2 valve has an effective area of 14.0 mm2 (Cv 0.78) and supports speeds of 30-800 mm/s.
No, the integrated 4M210-06 valve switches the cylinder directly from an AC24V terminal coil signal. Factory set to retract when energised, it can be reconfigured to extend-when-energised by repositioning the valve.
