Airtac SAIF Series Standard Cylinder with Valve SAIF32X250S-08E
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF32X250S-08E is a genuine double-acting ISO 15552 cylinder with a Ø32mm bore, 250mm 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 SAIF32X250S-08E
The AirTAC SAIF32X250S-08E is a double-acting ISO 15552 profile cylinder featuring a built-in 4M210-08 5/2 solenoid valve. Delivering a Cv of 0.89 and a 16.0 mm2 orifice, this integrated assembly switches itself from a single AC24V terminal coil signal. It includes an -S magnet for precise position detection using CMSE reed and DMSE electronic sensors. The manifold connects the valve to the cylinder using O8 x O5 PU tubing, keeping the setup compact.
While the base cylinder rates to 1.0 MPa, the internal pilot valve operates at 0.15-0.8 MPa, making 0.15-0.8 MPa the practical working range for this complete unit. At 0.5 MPa it provides 402 N of push force and 345 N of pull force. By default, the piston rod retracts when the coil is energised, but you can reconfigure it to extend-when-energised simply by repositioning the valve.

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)

| 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-08E Is Used
Decentralized Stations
Ideal for large machines with distributed stations, eliminating long tubing runs from a central panel by controlling the cylinder locally via a single AC24V wire.
Compact Clamping
Provides 402 N of push force at 0.5 MPa in tight spaces where mounting a separate 4M210 valve and cylinder individually would exceed the available envelope.
Sensor-Ready Actuation
The integrated -S magnet works directly with DMSE solid-state and CMSE reed switches for precise end-of-stroke confirmation in automated assembly lines.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF32X250S-08E the Right Choice?
Choose this 32mm bore if your application requires around 402 N of push force at 0.5 MPa; stepping up to the 40mm bore raises that to 628 N for heavier loads. The SAIF32X250S-08E excels in decentralized installations where running separate valve tubing back to a central manifold is costly or space-prohibitive. The AC24V terminal connection offers safe, low-voltage control drawing 3.5 VA with an IP65 rating and a 0.05 s response time.
Because the stroke is 250 mm, ensure adequate side-load support and use a guide mechanism to prevent rod binding. If your process requires holding a load without live air pressure, note that the 5/2 valve routes air but does not lock the piston; for true load-holding, consider the SAIL lock cylinder or BSAI clamp-lock series. When ordering a replacement, match the 32mm bore, 250mm stroke, 1/8" cylinder port, 1/4" valve port, AC24V voltage, terminal entry, 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 SAIF32X250S-08E FAQ
The built-in 4M210-08 valve has a 16.0 mm2 orifice and a Cv of 0.89. The 32mm bore cylinder generates 402 N of push force and 345 N of pull force at 0.5 MPa, with a maximum frequency of 5 cycles per second.
Yes, the SAIF series integrates the valve directly onto the cylinder. It operates on AC24V (3.5 VA) with a terminal entry. Factory-set to retract when energised, the valve can be repositioned to extend-when-energised, providing complete local control without external plumbing.
