Airtac SAIF Series Standard Cylinder with Valve SAIF32X225S-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF32X225S-08A is a genuine double-acting ISO 15552 cylinder with a Ø32mm bore, 225mm 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 SAIF32X225S-08A
The AirTAC SAIF32X225S-08A is a double-acting ISO 15552 profile cylinder featuring a built-in 4M210-08 5/2 solenoid valve. This specific configuration uses an AC220V terminal connection and includes a magnet for CMSE or DMSE sensors. The integrated valve offers an effective area of 16.0 mm2 (Cv 0.89), routing air directly through a PU tube (O8 x O5) manifold block. While the cylinder body rates to 1.0 MPa, the practical working pressure for this valved assembly is 0.15-0.8 MPa.
Generating 402N push force at 0.5 MPa, this 32mm bore unit eliminates the need for a separate remote valve. The factory setting retracts the piston rod when the coil is energised, but you can reposition the valve to extend on signal. Operating at 30-800 mm/s, it provides decentralized machine control from one electrical signal.

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)

|---|---|---|
| 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 SAIF32X225S-08A Is Used
Decentralized Assembly Stations
Eliminates remote valve plumbing by driving the 32mm bore directly from the built-in 4M210-08 valve, saving panel space.
Space-Tight Sorting
Provides 402N push force at 0.5 MPa in compact machinery where installing external pneumatic valves is physically impossible.
Retrofit Automation
Upgrades existing ISO 15552 setups with localized AC220V terminal control, using CMSE/DMSE sensors for position feedback.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF32X225S-08A the Right Choice?
Choose this self-valved SAIF32X225S-08A when decentralized stations or space-tight machines make running separate pneumatic tubing costly. If your application requires higher push force, stepping up to the 40mm bore yields 628N at 0.5 MPa. Because the stroke is 225mm, ensure adequate guiding to prevent rod side-loading. For exact replacement, match the 32mm bore, 225mm stroke, 1/4" valve port, AC220V terminal coil, PT threads, and -S magnet. Note that the 5/2 valve routes air but does not lock the load; for position holding, consider the SAIL lock series.
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 SAIF32X225S-08A FAQ
The 32mm bore generates 402N push and 345N pull force at 0.5 MPa. The built-in 4M210-08 5/2 valve provides a 16.0 mm2 effective area (Cv 0.89) with a maximum frequency of 5 cycles/sec.
The integrated 4M210 valve allows the cylinder to switch itself from one AC220V coil signal, drastically reducing tubing and panel space. By default, the rod retracts when energised, but it can be reconfigured to extend by repositioning the valve.
