Airtac SAIF Series Standard Cylinder with Valve SAIF32X350S-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF32X350S-08A is a genuine double-acting ISO 15552 cylinder with a Ø32mm bore, 350mm 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 SAIF32X350S-08A
The AirTAC SAIF32X350S-08A is a double-acting ISO 15552 profile cylinder featuring an integrated 4M210-08 5/2 solenoid valve. This specific SKU is configured with a 1/4" valve port, PT1/8 cylinder port, and an AC220V terminal coil drawing 3.5 VA. The integrated valve boasts a 16.0 mm2 orifice (Cv 0.89) and cycles up to 5 times per second. Because the valve manifold routes air internally via an O8xO5 PU tube, you eliminate remote plumbing and save panel space. The included -S magnet enables position sensing with AirTAC CMSE reed or DMSE electronic switches.
While the bare cylinder rates to 1.0 MPa, the practical operating range for this self-valved unit is 0.15-0.8 MPa. In its factory setting, the piston rod retracts when the coil is energised, but you can reconfigure it to extend-when-energised by repositioning the valve. At 0.5 MPa, this 32mm bore generates 402N of push force and 345N of pull force. The carbon steel rod and adjustable air cushions handle dynamic loads, though the 5/2 valve routes air and does not lock the load without live pressure.

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 SAIF32X350S-08A Is Used
Decentralized Stations
Eliminates the need for a remote valve island on large machines by switching directly from a single AC220V terminal signal.
Compact Assembly Lines
Fits space-tight machinery where routing pneumatic tubing to a separate valve is impractical, providing 402N push force.
Retrofit Automation
Upgrades existing ISO 15552 mounts easily, using the internal O8xO5 PU tube manifold to reduce external plumbing complexity.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF32X350S-08A the Right Choice?
Choose this 32mm bore when you need compact actuation up to 402N push force at 0.5 MPa. If your application requires greater thrust, stepping up to the 40mm bore yields 628N push at the same pressure. The SAIF32X350S-08A is ideal for decentralized stations where running individual valve tubing is costly, as one AC220V terminal connection drives the entire actuator. For load-holding tasks, note that the built-in valve is not a lock; consider an AirTAC SAIL lock cylinder instead. Because the 350mm stroke exceeds 300mm, ensure you use appropriate side-load guides to prevent rod bending and premature seal wear. Replacement units must match the 32mm bore, 350mm stroke, 1/4" valve port, AC220V voltage, terminal entry, PT threads, and the -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 SAIF32X350S-08A FAQ
At 0.5 MPa, this 32mm bore cylinder generates 402N of push force and 345N of pull force. The integrated 4M210-08 valve has an effective area of 16.0 mm2 (Cv 0.89) and supports a maximum frequency of 5 cycles per second.
No separate remote valve is needed; the manifold block switches the cylinder directly from the AC220V coil signal. By factory default, the rod retracts when the coil is energised, but you can reposition the valve to extend-when-energised if needed.
