Airtac SAIF Series Standard Cylinder with Valve SAIF32X250S-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF32X250S-08A is a genuine double-acting ISO 15552 cylinder with a Ø32mm bore, 250mm 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 SAIF32X250S-08A
The AirTAC SAIF32X250S-08A is a double-acting profile cylinder dimensionally interchangeable per ISO 15552, featuring a built-in 4M210-08 5/2 solenoid valve with a 16.0 mm2 flow area (Cv 0.89). It integrates an AC220V terminal coil drawing 3.5 VA, switching in 0.05 s with IP65 protection. The assembly includes a magnet for CMSE reed and DMSE electronic sensors. While the bare cylinder rates to 1.0 MPa, the integrated valve limits the practical SAIF operating range to 0.15-0.8 MPa.
This self-contained unit eliminates remote plumbing by routing air through an O8xO5 PU tube manifold, making it ideal for decentralized machine stations. The factory default retracts the piston rod when the coil is energised, but you can reposition the valve to extend on signal. In the 32 mm bore class, it delivers 402 N push and 345 N pull at 0.5 MPa, operating at speeds of 30-800 mm/s.

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 SAIF32X250S-08A Is Used
Decentralized Stations
Eliminates the need for a remote valve island on large machines by switching directly from a single AC220V signal at the cylinder.
Compact Assembly
Fits 32 mm bore tasks needing 402 N force in tight spaces where running separate valve tubing is costly or complex.
Wiring Retrofits
Ideal for upgrading pneumatic setups where adding a terminal-entry coil at the cylinder minimizes panel rewiring.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF32X250S-08A the Right Choice?
Choose this 32 mm bore when you need compact 402 N thrust at 0.5 MPa; step up to the 40 mm bore if your application requires 628 N push force. The SAIF32X250S-08A is specified with an AC220V terminal electrical entry, a PT1/4 cylinder port, and a 1/4 inch valve port. The -S magnet enables position feedback via CMSE or DMSE switches. When replacing, match the 250 mm stroke, 4M210-08 valve, AC220V coil, PT thread, and magnet status.
Because the stroke is 250 mm, ensure adequate guiding to prevent side-load wear on the rod seals. Remember that the 5/2 valve routes air but does not lock the load—use an AirTAC SAIL lock cylinder if static holding is required upon pressure loss.
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 SAIF32X250S-08A FAQ
At 0.5 MPa, this 32 mm bore cylinder generates 402 N push and 345 N pull force. The built-in 4M210-08 5/2 valve provides an effective flow area of 16.0 mm2 (Cv 0.89) with a maximum frequency of 5 cycles per second.
The factory setting retracts the rod when the AC220V coil is energised. Because it uses a 5/2 pilot valve rather than a spring, you can reposition the valve on the manifold to configure it for extend-when-energised operation without needing a separate remote valve.
