Airtac SAIF Series Standard Cylinder with Valve SAIF32X400-06B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF32X400-06B is a genuine double-acting ISO 15552 cylinder with a Ø32mm bore, 400mm stroke and a built-in 4M210-06 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 SAIF32X400-06B
The AirTAC SAIF32X400-06B is a double-acting ISO 15552 profile cylinder featuring an integrated 4M210-06 5/2 solenoid valve. This specific configuration uses a DC24V terminal entry coil consuming 3.0 W, protected to IP65 with a 0.05 s response time. The built-in valve provides an effective orifice of 14.0 mm2 (Cv 0.78) and routes air through an O8 x O5 PU tube, meaning the 1/8 valve port and 1/8 cylinder port are distinct connections.
Because the valve operates at 0.15-0.8 MPa, the practical working range for this assembled SAIF unit is 0.15-0.8 MPa despite the cylinder body rating of 1.0 MPa. Delivering 402 N of push force at 0.5 MPa, it eliminates the need for a remote valve bank, saving panel space and tubing for decentralized machine stations. The factory setting retracts the piston rod when the coil is energised, which can be reconfigured to extend-when-energised by repositioning the valve.

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 SAIF32X400-06B Is Used
Decentralized Stations
Ideal for large machines with decentralized stations, switching itself from one DC24V coil signal without running long valve tubing back to a central panel.
Space-Tight Machinery
The integrated 4M210 valve and manifold save valuable panel and machine envelope space where a separate valve island would not fit.
Retrofit Automation
Perfect for upgrading existing lines where plumbing new remote valve tubing is costly, providing a self-contained 32mm bore actuator.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF32X400-06B the Right Choice?
Choose this 32mm bore if your application requires around 402 N of push force at 0.5 MPa; stepping up to a 40mm bore yields 628 N for heavier loads, while dropping to a smaller profile is not available in the SAIF range. The self-valved design of the SAIF32X400-06B beats a separate cylinder and remote valve in space-tight or decentralized installations by cutting plumbing and wiring to a single DC24V coil signal.
For this 400mm stroke, add an external guide to manage side loads and prevent rod deflection. To replace this unit, match the 32mm bore, 400mm stroke, 06 (1/8) valve port, DC24V voltage, terminal entry, PT thread, and standard carbon steel rod. Note that the 5/2 valve routes air and is not a lock; if you need to hold a load without live pressure, use a SAIL lock or BSAI clamp-lock cylinder instead.
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 SAIF32X400-06B FAQ
The 32mm bore provides 402 N push and 345 N pull force at 0.5 MPa. The built-in 4M210-06 valve has a 14.0 mm2 orifice (Cv 0.78) and a max frequency of 5 cycles/sec.
By default, the factory setting retracts the rod when the DC24V coil is energised. You can reconfigure it to extend-when-energised by repositioning the 5/2 valve on the manifold block.
