Airtac SAIF Series Standard Cylinder with Valve SAIF32X150-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF32X150-08B 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 SAIF32X150-08B
The AirTAC SAIF32X150-08B is a double-acting ISO 15552 profile cylinder with a built-in 4M210-08 5/2 solenoid valve, offering a Cv of 0.89. Driven by a DC24V terminal coil drawing 3.0W, it responds in 0.05s with an IP65 rating. The integrated manifold uses an O8xO5 PU tube to bridge the valve and cylinder, eliminating the need for external tubing between a remote valve and the cylinder port.
While the cylinder body rates up to 1.0 MPa, the practical operating range for this valved assembly is 0.15-0.8 MPa. Generating 402N of push force at 0.5 MPa, it is designed for decentralized machine stations. From the factory setting, the piston rod retracts when the coil is energised, but you can reposition the valve to extend-when-energised if your sequence requires it.

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 SAIF32X150-08B Is Used
Decentralized Stations
Ideal for large machines with distributed stations, minimizing panel space by mounting the valve directly on the cylinder.
Compact Assembly Lines
Fits into space-tight machinery where running separate remote valve tubing is impractical or too costly.
Retrofit Automation
Simplifies machine upgrades by replacing a separate cylinder and remote valve setup with a single self-switching unit.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF32X150-08B the Right Choice?
Choose this 32mm bore when you need compact actuation; stepping up to the 40mm bore increases the 0.5 MPa push force to 628N for heavier moving masses. The SAIF32X150-08B excels in tight layouts where running separate valve plumbing is costly, as one DC24V terminal connection drives the cylinder directly. The valve port is 1/4" while the cylinder port is 1/8", so verify your fittings accordingly.
For stroke lengths like 150mm, ensure adequate guiding to prevent side-load damage to the carbon steel rod. Remember that the built-in 5/2 valve routes air but does not lock the load; if you need true position holding without live pressure, select the SAIL lock series instead. Replacement matches require the exact 32mm bore, 150mm stroke, 1/4" valve port, DC24V terminal entry, PT thread, and no 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 SAIF32X150-08B FAQ
The 32mm bore generates 402N push force and 345N pull force at 0.5 MPa. The built-in 4M210-08 valve provides an effective area of 16.0 mm2 (Cv 0.89) for reliable airflow.
No, it features a built-in 4M210 5/2 valve. By default, the rod retracts when the DC24V coil is energised, but the valve can be repositioned to extend-when-energised. No separate remote valve is needed.
