Airtac SAIF Series Standard Cylinder with Valve SAIF32X500S-08F
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF32X500S-08F is a genuine double-acting ISO 15552 cylinder with a Ø32mm bore, 500mm 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 SAIF32X500S-08F
The AirTAC SAIF32X500S-08F is a double-acting ISO 15552 profile cylinder with a built-in 4M210-08 5/2 solenoid valve, delivering a Cv of 0.89 and a 16.0 mm2 effective orifice. It features a 32mm bore with a 500mm stroke, generating 402N of push force at 0.5 MPa. Driven by a DC12V terminal entry coil consuming 3.0 W, it activates in 0.05 s or less with an IP65 rating. Because the cylinder body rates to 1.0 MPa but the integrated valve operates at 0.15-0.8 MPa, the practical working pressure for this assembled unit is 0.15-0.8 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. This self-switching design eliminates the need for a remote valve, reducing tubing and panel space for decentralized installations. The manifold connects to the cylinder via O8 x O5 PU tubing, and this -S variant includes a magnet for position sensing with AirTAC CMSE (reed) and 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)
| 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 SAIF32X500S-08F Is Used
Decentralized Automation
Perfect for large machines with decentralized stations, eliminating long air tubing runs back to a central valve island.
Compact Assembly Machines
Saves valuable panel space by integrating the 4M210 valve directly on the cylinder, ideal for tight machine envelopes.
Retrofit & Upgrades
Simplifies upgrades on existing lines where adding new remote valve plumbing is costly or physically impossible.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF32X500S-08F the Right Choice?
Choose this 32mm bore if your application requires around 402N push force at 0.5 MPa; stepping up to a 40mm bore yields 628N, while dropping down is not available below 32mm in the SAIF range. A self-valved SAIF cylinder beats a separate cylinder plus remote valve when you need to minimize wiring and plumbing across decentralized stations. To replace this unit, match the 32mm bore, 500mm stroke, 4M210-08 valve with PT1/4 threads, DC12V voltage, terminal entry, and the -S magnet. Because the stroke is 500mm, ensure adequate guide support to prevent rod side-loading and premature seal wear. Note that the 5/2 valve routes air but does not lock the load; for position holding, consider an AirTAC SAIL lock cylinder.
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 SAIF32X500S-08F FAQ
The 32mm bore generates 402N push force at 0.5 MPa and 724N at 0.9 MPa. The built-in 4M210-08 valve provides a 16.0 mm2 effective area (Cv 0.89) with a maximum frequency of 5 cycles per second.
It uses a DC12V terminal entry coil (3.0 W, IP65). The 5/2 valve holds position via internal pilot pressure, not a spring. Factory setting retracts the rod when energised, but you can reposition the valve to extend-when-energised, removing the need for a separate remote valve.
