Airtac SAIF Series Standard Cylinder with Valve SAIF32X175S-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF32X175S-08A 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-08A
The AirTAC SAIF32X175S-08A is a double-acting ISO 15552 profile cylinder with a built-in 4M210-08 5/2 solenoid valve, yielding an effective flow of 16.0 mm2 (Cv 0.89). Driven by an AC220V terminal entry coil drawing 3.5 VA, it integrates switching directly on the actuator. Although the cylinder body rates to 1.0 MPa, the integrated valve limits the practical working pressure to 0.15-0.8 MPa. At 0.5 MPa this 32mm bore generates 402N of push force and 345N of pull force.
By routing air through a manifold block and short PU tubing (O8 x O5), this unit eliminates remote plumbing and saves panel space for decentralized machine stations. The factory setting retracts the piston rod when the coil is energised, but you can reposition the valve to extend-when-energised if your logic requires it. This -S variant includes a magnet for position sensing with AirTAC CMSE reed and DMSE electronic solid-state 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-08A Is Used
Decentralized Machine Stations
Ideal for large machines where running individual valve lines back to a central manifold is impractical, saving panel space and tubing.
Compact Clamping Jigs
Provides 402N push force at 0.5 MPa for small part clamping, with the built-in 4M210 valve ensuring rapid 5 cycle/sec switching.
Retrofit Automation
Perfect for upgrading existing ISO 15552 fixtures where adding a separate pneumatic control panel would be too expensive.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF32X175S-08A the Right Choice?
Choose this self-valved SAIF32X175S-08A when a single coil signal must drive a decentralized station and running separate valve tubing is costly. If you need higher thrust, stepping up to the 40mm bore yields 628N push force at 0.5 MPa. Keep in mind the 5/2 valve routes air but does not lock the load; for position holding under pressure loss, select the SAIL lock or BSAI clamp-lock series instead. To replace this unit, match the 32mm bore, 175mm stroke, 4M210-08 valve with PT1/4 cylinder ports, AC220V terminal coil, and the -S magnet. Since the 175mm stroke exceeds 300mm? No, but for any stroke over 300mm, ensure external guides to manage side loads.
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-08A FAQ
At 0.5 MPa, the 32mm bore provides 402N push and 345N pull force. The integrated 4M210-08 5/2 valve has a 16.0 mm2 orifice (Cv 0.89) and operates at a max frequency of 5 cycles per second.
It uses an internally piloted 5/2 valve that holds position via pilot pressure, not a spring. This specific model uses an AC220V terminal coil (3.5 VA, IP65). The factory default retracts the rod when energised, but it can be reconfigured to extend-when-energised by repositioning the valve.
