Airtac SAIF Series Standard Cylinder with Valve SAIF32X450S-08E
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF32X450S-08E 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 SAIF32X450S-08E
The AirTAC SAIF32X450S-08E is a double-acting ISO 15552 profile cylinder equipped with a built-in 4M210-08 5/2 solenoid valve. This integrated assembly delivers a Cv of 0.89 and operates on an AC24V terminal coil drawing 3.5 VA. Because the manifold routes air directly to the 1/4 inch cylinder ports via O8 x O5 PU tubing, you eliminate remote valve plumbing entirely. The practical operating pressure for this self-switching unit is 0.15-0.8 MPa, delivering a push force of 402N at 0.5 MPa.
By driving the cylinder from a single coil signal with an IP65-rated 0.05s response, this decentralized setup saves substantial panel space. The factory default setting retracts the carbon steel piston rod when the coil is energised, but you can reposition the valve to extend on signal. This -S variant includes a magnet for position sensing with CMSE reed or DMSE electronic switches.

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 SAIF32X450S-08E Is Used
Decentralized Stations
Ideal for large machines with multiple stations, eliminating long tubing runs by switching the 32mm bore directly at the point of actuation.
Space-Constrained Retrofits
Perfect for upgrading older equipment where adding a remote valve manifold is physically impossible or too costly to plumb.
Light Assembly Automation
Provides compact 402N push force for parts handling and clamping tasks that require reliable 5/2 pneumatic switching.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF32X450S-08E the Right Choice?
Choose this 32mm bore when your application requires a 402N push force at 0.5 MPa; step up to the 40mm bore if you need 628N. The 450mm stroke is well within the 1000mm maximum for this bore, but at this length you should guide the load to prevent excessive side-load on the rod seals. The integrated 4M210 valve with a 1/4 inch port eliminates the need for a separate valve island, making it highly effective for retrofitting decentralized stations where running new tubing is costly.
When specifying a replacement, match the 32mm bore, 450mm stroke, 08 (1/4 inch) valve port, AC24V voltage, PT thread, terminal entry, and the -S magnet. Note that while the 5/2 valve and adjustable air cushions control motion, neither holds the load without live air pressure; for true mechanical locking, consider the SAIL series.
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 SAIF32X450S-08E FAQ
The built-in 4M210-08 valve has an effective area of 16.0 mm2 (Cv 0.89). The 32mm bore cylinder generates a push force of 402N and a pull force of 345N at 0.5 MPa operating pressure.
Yes. The factory setting retracts the rod when the AC24V coil is energised, but you can reconfigure the valve to extend-when-energised simply by repositioning the valve on the manifold block.
