Airtac SAIF Series Standard Cylinder with Valve SAIF32X400S-08F
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF32X400S-08F 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-08F
The AirTAC SAIF32X400S-08F is a double-acting ISO 15552 profile cylinder featuring an integrated 4M210-08 5/2 solenoid valve. Driven by a DC12V terminal coil consuming 3.0 W, it eliminates the need for a remote valve island, saving panel space and plumbing. The assembly includes a position magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors, and uses an O8xO5 PU tube to link the manifold to the cylinder.
Although the bare cylinder rates to 1.0 MPa, the built-in valve operates at 0.15-0.8 MPa, establishing the practical working range for this unit. Delivering 402 N of push force at 0.5 MPa, it switches itself from a single coil signal. By default, the piston rod retracts when the coil is energised, but you can reconfigure the valve to extend-when-energised by repositioning it.

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 SAIF32X400S-08F Is Used
Decentralized Machine Stations
Ideal for large automated lines where installing a local DC12V valve eliminates long pneumatic runs back to a central panel.
Compact Assembly Robotics
Fits space-tight cells by combining the ISO 15552 actuator and 5/2 valve into one integrated package with minimal envelope.
Retrofit & Upgrade Projects
Perfect for upgrading existing 32mm bore setups where adding separate valve plumbing is costly or physically restricted.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF32X400S-08F the Right Choice?
Choose this self-valved SAIF unit when decentralized stations require localized control without running separate valve tubing across a large machine. If your application needs greater thrust, stepping up to a 40mm bore provides 628 N of push force at 0.5 MPa. For load-holding applications, note that this 5/2 valve routes air and does not lock the load; consider the SAIL series for pneumatic locking.
This 400mm stroke variant requires external guidance to manage side loads and prevent rod binding over the extended travel. To replace this SKU exactly, match the 32mm bore, 400mm stroke, 4M210-08 valve (1/4" valve port, 1/8" cylinder port), DC12V terminal coil, PT thread, and the -S magnet option.
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-08F FAQ
The 32mm bore generates 402 N push and 345 N pull force at 0.5 MPa. The built-in 4M210-08 valve provides a 16.0 mm2 orifice with a Cv of 0.89, supporting a maximum cycle frequency of 5 cycles per second.
Yes. The factory default setting retracts the piston rod when the DC12V coil is energised, but you can reconfigure it to extend-when-energised simply by repositioning the valve on the manifold block.
