Airtac SAIF Series Standard Cylinder with Valve SAIF32X450-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF32X450-08A is a genuine double-acting ISO 15552 cylinder with a Ø32mm bore, 450mm 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 SAIF32X450-08A
The AirTAC SAIF32X450-08A is a double-acting ISO 15552 profile cylinder featuring an integrated 4M210-08 5/2 solenoid valve. This specific build utilizes an AC220V terminal coil and delivers a Cv of 0.89 with a 16.0 mm2 orifice. 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 the assembled SAIF unit is 0.15-0.8 MPa. It provides 402N of push force at 0.5 MPa.
By default, the piston rod retracts when the coil is energised, but you can reconfigure it to extend-when-energised simply by repositioning the valve. The manifold block connects to the cylinder using O8 x O5 PU tubing, meaning the 1/4" valve port differs from the cylinder's 1/8" port. This decentralized design eliminates the need for a separate remote valve, saving panel space and plumbing.

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 SAIF32X450-08A Is Used
Decentralized Machine Stations
Eliminates remote valve plumbing by driving the cylinder directly from its integrated 4M210 valve, saving panel space across large factory layouts.
Compact Assembly Lines
Fits tight envelopes where running separate pneumatic tubing is difficult, providing 402N push force with a self-contained AC220V signal.
Retrofit Automation
Ideal for upgrading older machines to self-switching ISO 15552 actuators without adding a new centralized valve manifold.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF32X450-08A the Right Choice?
Choose this 32mm bore if your application requires a compact, self-switching actuator delivering 402N push force at 0.5 MPa; step up to a 40mm bore if you need 628N. The 450mm stroke is well within the 1000mm maximum standard stroke for this bore, but at this length you should ensure adequate side-load guidance to prevent rod binding. The integrated 4M210-08 valve handles its own switching via the AC220V terminal connection, which is ideal for machines where running pneumatic tubing to a remote valve bank is costly or impractical.
Remember that the built-in 5/2 valve routes air but does not lock the load; if you need true position holding without live pressure, consider the AirTAC SAIL lock cylinder or BSAI clamp-lock instead. For drop-in replacement, match the 32mm bore, 450mm stroke, 1/4" valve port, AC220V voltage, terminal entry, PT thread, and standard carbon steel rod. Note that a magnet for CMSE or DMSE sensors is not included in this configuration.
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 SAIF32X450-08A FAQ
At 0.5 MPa, this 32mm bore cylinder provides 402N of push force and 345N of pull force. The integrated 4M210-08 valve has a Cv of 0.89 and a 16.0 mm2 effective area.
No, the 4M210-08 is an internally piloted 5/2 solenoid valve. It switches the cylinder directly from the AC220V terminal coil signal. By default, the rod retracts when energised, but you can reposition the valve to extend-when-energised.
