Airtac SAIF Series Standard Cylinder with Valve SAIF32X150-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF32X150-08A 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 SAIF32X150-08A
The AirTAC SAIF32X150-08A 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 effective orifice, it generates 402N of push force at 0.5 MPa. Driven by an AC220V terminal coil drawing 3.5 VA with IP65 protection, it responds in 0.05 s. The integrated manifold uses O8 x O5 PU tubing to bridge the valve and cylinder, making it ideal for decentralized stations where routing separate valve lines is costly.
While the bare cylinder rates to 1.0 MPa, the practical operating pressure for this assembled SAIF unit is 0.15-0.8 MPa because the internal pilot valve limits the range. From the factory, the piston rod retracts when the coil is energised, but you can reposition the valve to extend-when-energised. The 5/2 valve holds its shifted state via internal pilot pressure, not a spring, meaning it routes air continuously without locking the load.

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 SAIF32X150-08A Is Used
Decentralized Machine Stations
Eliminates the need for a central valve bank on large machines by switching locally from an AC220V terminal signal, minimizing plumbing complexity.
Compact Assembly Tooling
Fits tight envelopes where running separate valve tubing is impossible, delivering 402N of push force at 0.5 MPa for small clamping or positioning tasks.
Retrofit Automation Systems
Ideal for upgrading older machines by adding self-contained pneumatic motion without installing new valve islands or extensive air manifolds.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF32X150-08A the Right Choice?
Choose this 32mm bore when 402N of push at 0.5 MPa is sufficient; if your application needs the next force class, stepping up to the 40mm bore yields 628N. The SAIF32X150-08A excels over a separate cylinder and remote valve by drastically cutting panel footprint and tubing runs. With a 150mm stroke, ensure your machine design provides adequate guide support to prevent rod side-loading. For replacements, verify the 32mm bore, 150mm stroke, 1/4" cylinder port, 08 (1/4") valve port, AC220V voltage, terminal entry, and PT thread. Because this SKU lacks the -S magnet, add one if you require CMSE reed or DMSE electronic sensors for position feedback.
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 SAIF32X150-08A FAQ
The 32mm bore generates 402N push and 345N pull force at 0.5 MPa. The built-in 4M210-08 valve provides a 16.0 mm2 effective area (Cv 0.89) and can cycle up to 5 times per second.
No separate valve is needed. The integrated 4M210-08 5/2 valve switches the cylinder directly from the AC220V coil signal. By factory default, the rod retracts when energised, but you can reposition the valve to extend-when-energised.
