Airtac SAIF Series Standard Cylinder with Valve SAIF32X150S-08F
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF32X150S-08F is a genuine double-acting ISO 15552 cylinder with a Ø32mm bore, 150mm 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 SAIF32X150S-08F
The AirTAC SAIF32X150S-08F is a double-acting ISO 15552 profile cylinder with a built-in 4M210-08 5/2 solenoid valve. It delivers a 402N push force at 0.5 MPa and uses an O8xO5 PU tube between the manifold and cylinder. The unit operates on DC12V via a terminal electrical entry, drawing 3.0 W with an IP65 rating and a 0.05s response time. This specific configuration includes a magnet for CMSE reed and DMSE electronic sensors.
Because the cylinder rates to 1.0 MPa but the integrated valve operates at 0.15-0.8 MPa, the practical working range for this assembled unit is 0.15-0.8 MPa. The factory setting retracts the piston rod when the coil is energised, but you can reposition the valve to extend-when-energised. By switching itself from one coil signal, it eliminates remote valves and saves 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 (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 SAIF32X150S-08F Is Used
Decentralized Stations
Ideal for large machines with decentralized stations, eliminating the need for long tubing runs to a central valve island.
Space-Tight Machines
The integrated 4M210 valve manifold saves valuable panel and machine envelope space in compact assemblies.
Retrofit Automation
Perfect for upgrading existing setups where adding external valves and complex plumbing is prohibitive.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF32X150S-08F the Right Choice?
Choose this 32mm bore if you need compact actuation up to 402N push at 0.5 MPa; step up to a 40mm bore if your application requires 628N. The self-valved SAIF design is ideal when running pneumatic tubing to a remote valve is costly or space-prohibitive. This model features a PT tapered port thread, a 1/8 cylinder port, and a 1/4 valve port. The carbon steel rod and 150mm stroke suit general automation. Note that the 5/2 valve routes air and is not a lock; for load-holding, consider the SAIL series. Replacement requires matching bore, stroke, valve port, DC12V voltage, terminal entry, PT thread, and the -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 SAIF32X150S-08F FAQ
At 0.5 MPa, this 32mm bore cylinder provides a 402N push force and a 345N pull force. 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.
Yes. The factory setting retracts the rod when the DC12V coil is energised, but you can reposition the valve on the manifold to make it extend-when-energised. This 5/2 valve holds its position via internal pilot pressure, not a spring.
