Airtac SAIF Series Standard Cylinder with Valve SAIF32X150S-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF32X150S-08A 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-08A
The AirTAC SAIF32X150S-08A is a double-acting ISO 15552 profile cylinder featuring a built-in 4M210-08 5/2 solenoid valve. This integrated manifold design eliminates the need for a remote valve, drastically reducing plumbing and panel space for decentralized machine stations. Driven by an AC220V terminal coil drawing 3.5 VA, it responds in 0.05 s. The unit includes a magnet for CMSE reed and DMSE electronic sensors.
While the bare cylinder rates to 1.0 MPa, the practical operating range for this valved assembly is 0.15-0.8 MPa. It delivers 402 N of push force at 0.5 MPa. The factory setting retracts the piston rod when the coil is energised, but you can reposition the valve to extend-when-energised. The manifold connects via O8xO5 PU tubing, and the 1/4" valve port differs from the 1/8" cylinder port.

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 SAIF32X150S-08A Is Used
Decentralized Stations
Eliminates remote valve banks on large machines by switching directly from a single AC220V terminal signal, saving wiring and tubing.
Space-Tight Machinery
The integrated 4M210-08 valve manifold minimizes envelope size, fitting perfectly into compact assemblies where external plumbing cannot fit.
Retrofit Automation
Ideal for upgrading existing lines where routing new air tubing back to a central panel is cost-prohibitive or physically impossible.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF32X150S-08A the Right Choice?
Choose this 32mm bore when you need compact actuation delivering 402 N push force at 0.5 MPa; step up to the 40mm bore if your application requires 628 N. The self-valved SAIF architecture is ideal for space-tight machines where running separate valve tubing is costly, as one AC220V terminal coil signal drives the entire cylinder. For load-holding applications, note that the 5/2 valve routes air but does not lock the piston; consider the SAIL series for pneumatic locking.
When ordering a replacement, verify the 150mm stroke, 1/4" valve port, 1/8" cylinder port, AC220V voltage, PT threaded port, and the -S magnet requirement. Since the stroke is under 300mm, standard side-load concerns are minimal, but always ensure axial alignment to maximize seal life.
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-08A FAQ
The built-in 4M210-08 valve has an effective area of 16.0 mm2 (Cv 0.89). The 32mm bore cylinder generates 402 N of push force and 345 N of pull force at 0.5 MPa.
Yes. The factory default retracts the rod when the AC220V coil is energised, but you can reposition the 5/2 valve on the manifold to extend-when-energised without changing the wiring.
