Airtac SAIF Series Standard Cylinder with Valve SAIF32X175S-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF32X175S-08B is a genuine double-acting ISO 15552 cylinder with a Ø32mm bore, 175mm 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 SAIF32X175S-08B
The AirTAC SAIF32X175S-08B is a double-acting ISO 15552 profile cylinder featuring an integrated 4M210-08 5/2 solenoid valve. This specific configuration uses a DC24V terminal connection drawing 3.0 W, and the valve provides a 16.0 mm2 effective area (Cv 0.89). Because the cylinder body rates to 1.0 MPa but the built-in valve operates at 0.15-0.8 MPa, the practical working range for this assembled unit is 0.15-0.8 MPa. It delivers 402 N of push force at 0.5 MPa.
The integrated manifold uses O8 x O5 PU tubing to link the valve to the cylinder, meaning the 1/4 inch valve port differs from the 1/8 inch cylinder port. By default, the factory setting retracts the piston rod when the coil is energised, though you can reconfigure it to extend-when-energised by repositioning the valve. The -S magnet option enables position sensing with AirTAC CMSE reed or DMSE electronic switches.

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 SAIF32X175S-08B Is Used
Decentralized Stations
Ideal for large machines with distributed stations, eliminating remote valve plumbing by driving the cylinder directly from a single DC24V signal.
Compact Assembly
Suits space-tight machinery where panel space is at a premium, using the integrated 4M210 valve and O8xO5 PU manifold tubing to minimize footprint.
Retrofit Upgrades
Perfect for upgrading existing lines where adding new valve banks is impractical, providing a 5/2 valve directly on the 32mm ISO 15552 profile body.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF32X175S-08B the Right Choice?
Choose this 32mm bore if your application requires a compact, self-switching actuator that delivers 402 N push force at 0.5 MPa. If you need greater thrust, stepping up to the 40mm bore yields 628 N push at 0.5 MPa. The SAIF series excels in decentralized installations where running separate valve tubing back to a main panel is costly or space-prohibitive; one DC24V signal directly drives the cylinder. For load-holding requirements, note that the 5/2 valve routes air but does not lock the load—consider the SAIL series for pneumatic locking. When replacing this unit, match the 175mm stroke, 1/4 inch valve port, DC24V terminal coil, PT thread, and -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 SAIF32X175S-08B FAQ
The 32mm bore generates 402 N of push force and 345 N of pull force at 0.5 MPa. The built-in 4M210-08 valve has a 16.0 mm2 orifice with a Cv of 0.89, supporting a maximum cylinder speed of 800 mm/s.
No separate valve is needed. The integrated 5/2 valve holds its position via internal pilot pressure. By default, the factory setting retracts the rod when the DC24V coil is energised, but you can reposition the valve to extend-when-energised.
