Airtac SAIF Series Standard Cylinder with Valve SAIF32X225-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF32X225-08A 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 SAIF32X225-08A
The AirTAC SAIF32X225-08A is a double-acting profile cylinder with an integrated 4M210-08 5/2 solenoid valve, delivering a Cv of 0.89. Driven by an AC220V terminal coil drawing 3.5 VA, it eliminates the need for a remote valve bank. The assembly operates within a 0.15-0.8 MPa range, as the built-in valve limits the cylinder's 1.0 MPa capacity. At 0.5 MPa it generates 402N of push force.
By default, the piston rod retracts when the coil is energised, but you can reposition the valve to extend on signal. The manifold connects to the cylinder via an O8xO5 PU tube, distinguishing the 1/4" valve port from the cylinder's 1/8" port. This self-contained design minimizes plumbing and panel space for decentralized machine stations.

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 SAIF32X225-08A Is Used
Decentralized Stations
Eliminates remote valve plumbing by switching locally from an AC220V signal across large machine grids.
Compact Clamping
Provides 402N push force at 0.5MPa in tight assembly cells where panel space is restricted.
Retrofit Upgrades
Simplifies machine upgrades by avoiding the cost of routing new pneumatic tubing to a central manifold.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF32X225-08A the Right Choice?
Choose this 32mm bore when your application requires up to 402N push force at 0.5MPa; stepping up to a 40mm bore yields 628N if higher thrust is needed. The SAIF32X225-08A is ideal for space-tight machines where running separate valve tubing is costly, as it switches directly from one AC220V terminal signal. Because the 5/2 valve only routes air, it cannot hold the load without live pressure—use an AirTAC SAIL lock cylinder for fail-safe holding. For a replacement, match the 32mm bore, 225mm stroke, 1/4" valve port, AC220V voltage, terminal entry, PT thread, and no magnet. Given the 225mm stroke, ensure proper guide support to prevent rod side-loading.
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 SAIF32X225-08A FAQ
The 32mm bore generates 402N push and 345N pull force at 0.5MPa. The integrated 4M210-08 valve has a 16.0mm2 orifice with a Cv of 0.89.
No, the built-in 5/2 valve routes air but does not lock the piston. For position holding without live pressure, consider an AirTAC SAIL lock cylinder.
