Airtac SAIF Series Standard Cylinder with Valve SAIF32X350-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF32X350-08B 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 SAIF32X350-08B
The AirTAC SAIF32X350-08B is a double-acting ISO 15552 profile cylinder featuring an integrated 4M210-08 5/2 solenoid valve. This specific SKU is configured with a DC24V terminal coil and a PT 1/4 valve port, delivering a Cv of 0.89 and a 16.0 mm2 effective area. Because the cylinder body rates to 1.0 MPa but the internal pilot valve operates at 0.15-0.8 MPa, the practical working pressure for this assembled unit is 0.15-0.8 MPa. The 32mm bore generates 402N of push force at 0.5 MPa.
By mounting the valve directly via a manifold block and O8 x O5 PU tubing, this unit switches itself from one coil signal, eliminating remote plumbing. The factory setting retracts the rod when the coil is energised, though you can reposition the valve to extend-when-energised. Driven by a DC24V coil consuming 3.0 W with IP65 protection and a 0.05 s response, it suits decentralized stations perfectly.

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 SAIF32X350-08B Is Used
Decentralized Stations
Ideal for large machines with distributed control points, using the DC24V terminal coil to actuate the cylinder locally without a remote valve bank.
Space-Tight Machinery
The integrated 4M210-08 valve and manifold block save valuable panel and footprint space in compact assembly equipment.
Retrofit Automation
Perfect for upgrading existing lines where routing new valve tubing is costly, providing a self-switching 32mm bore solution.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF32X350-08B the Right Choice?
Select this 32mm bore when your application requires 402N push force at 0.5 MPa; if you need more thrust, stepping up to the 40mm bore yields 628N under the same pressure. A self-valved SAIF32X350-08B beats a separate cylinder and remote valve when panel space is tight and running tubing across a large machine is costly. The 4M210-08 valve uses a 1/4 port, while the cylinder port is 1/8. Remember the 5/2 valve routes air but does not lock the load; for position holding, consider SAIL.
With a 350mm stroke, you must account for side loads and use a guide to prevent rod binding. To replace this unit, match the 32mm bore, 350mm stroke, 08 valve port, DC24V voltage, terminal entry, PT thread, and no magnet. The cylinder speed ranges from 30-800 mm/s.
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 SAIF32X350-08B FAQ
The 32mm bore provides 402N push and 345N pull force at 0.5 MPa. The built-in 4M210-08 valve has a 16.0 mm2 orifice with a Cv of 0.89.
No, the 5/2 valve routes air but does not lock the load; for holding, use SAIL. The factory setting retracts the rod when energised, but you can reposition the valve to extend-when-energised.
