Airtac SAIF Series Standard Cylinder with Valve SAIF32X400S-08C
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF32X400S-08C is a genuine double-acting ISO 15552 cylinder with a Ø32mm bore, 400mm 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 SAIF32X400S-08C
The AirTAC SAIF32X400S-08C is a double-acting ISO 15552 profile cylinder featuring an integrated 4M210-08 5/2 solenoid valve. This built-in valve provides a Cv of 0.89 and eliminates the need for a remote valve bank, saving panel space and reducing plumbing complexity across decentralized machine stations. Equipped with a PT1/8 cylinder port and a PT1/4 valve port, the manifold connects via an O8xO5 PU tube. Driven by an AC110V terminal entry coil drawing 3.5 VA, it activates in 0.05 s or less with IP65 protection.
While the bare cylinder rates to 1.0 MPa, the practical operating range for this assembled SAIF unit is 0.15-0.8 MPa due to the internal pilot valve limits. It delivers 402 N of push force at 0.5 MPa. By factory default, the piston rod retracts when the coil is energised, but you can reposition the valve to extend-when-energised. The -S magnet option supports position sensing with AirTAC CMSE reed or 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)

| 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 SAIF32X400S-08C Is Used
Decentralized Assembly Lines
Perfect for large machines with scattered stations, eliminating long tubing runs back to a central valve island.
Space-Constrained Mechanisms
The built-in valve manifold shrinks the overall envelope, fitting into tight robotics or handling cells.
Retrofit Automation
Ideal for upgrading older machines where adding new air lines is difficult; just supply an AC110V signal.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF32X400S-08C the Right Choice?
Choose this 32mm bore if your application requires the 402 N push force at 0.5 MPa; step up to the 40mm bore if you need 628 N. The 400mm stroke is well within the 1000mm maximum standard stroke for this bore, but at this length you should account for potential side-loading and use a guide to prevent rod binding. The integrated valve makes this model ideal for space-tight machines where running separate valve tubing is costly. Remember that the 5/2 valve routes air but does not lock the load; for true position holding, consider the SAIL lock cylinder. To replace this exact unit, match the 32mm bore, 400mm stroke, PT1/4 valve port, AC110V 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 SAIF32X400S-08C FAQ
The 32mm bore generates 402 N of push force and 345 N of pull force at 0.5 MPa. The integrated 4M210-08 valve provides an effective area of 16.0 mm2 (Cv 0.89) with a maximum frequency of 5 cycles per second.
Yes. The factory default setting retracts the rod when the AC110V coil is energised, but you can reconfigure it to extend-when-energised by simply repositioning the built-in 5/2 valve on the manifold block.
