Airtac SAIF Series Standard Cylinder with Valve SAIF32X75-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF32X75-08B is a genuine double-acting ISO 15552 cylinder with a Ø32mm bore, 75mm 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 SAIF32X75-08B
The AirTAC SAIF32X75-08B is a double-acting profile cylinder with a built-in 4M210-08 5/2 solenoid valve, delivering a Cv of 0.89. It features a 32mm bore, 75mm stroke, and generates 402N of push force at 0.5 MPa. The integrated manifold connects via an O8xO5 PU tube, utilizing a PT1/4 valve port while the cylinder itself uses a PT1/8 port. This assembly operates within a practical 0.15-0.8 MPa range, as the valve limits the cylinder's 1.0 MPa capacity.
Driven by a DC24V terminal coil consuming 3.0 W, it achieves IP65 protection and responds in 0.05 s. By default, the piston rod retracts when the coil is energised, but you can reposition the valve to extend-when-energised. This self-switching design eliminates remote plumbing, saving panel space for decentralized machine stations. The standard carbon steel rod and extruded aluminum barrel make it dimensionally interchangeable per ISO 15552.

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 SAIF32X75-08B Is Used
Decentralized Machine Stations
Eliminates the need for a remote valve island on large machines by driving the cylinder directly from a single DC24V terminal signal.
Compact Assembly Lines
Fits space-tight zones where running separate pneumatic tubing is impractical, delivering 402N push force with a built-in 4M210 valve.
Retrofit Automation
Ideal for upgrading older systems where adding centralized valve plumbing is costly, offering a self-contained 5/2 switching solution.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF32X75-08B the Right Choice?
Choose this 32mm bore when 402N of push force at 0.5 MPa is sufficient; step up to the 40mm bore if you need 628N. The SAIF32X75-08B excels where running separate valve tubing is costly, as one DC24V signal directly controls the cylinder. The 4M210 valve cycles up to 5 times per second, matching the 30-800 mm/s speed range. Because the 5/2 valve routes air without locking it, do not use it for position holding; consider SAIL for mechanical lock requirements.
When replacing, verify the 32mm bore, 75mm stroke, 1/4" valve port, DC24V voltage, terminal entry, PT thread, and absence of a magnet. The cylinder port is 1/8". Stroke is under the 300mm threshold, so side-load guides are less critical here.
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 SAIF32X75-08B FAQ
At 0.5 MPa, the 32mm bore provides 402N of push force and 345N of pull force. At 0.7 MPa, the push force increases to 563N.
No, the 5/2 solenoid valve routes air but does not lock the load. By default, the rod retracts when the DC24V coil is energised, but it can be repositioned to extend-when-energised. For true load holding, use a SAIL lock cylinder.
