Airtac SAIF Series Standard Cylinder with Valve SAIF32X125S-08E
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF32X125S-08E is a genuine double-acting ISO 15552 cylinder with a Ø32mm bore, 125mm 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 SAIF32X125S-08E
The AirTAC SAIF32X125S-08E is a double-acting profile cylinder with a built-in 4M210-08 5/2 solenoid valve, delivering a Cv of 0.89. Driven by an AC24V terminal coil drawing 3.5 VA, it switches itself from one electrical signal. The base cylinder is dimensionally interchangeable per ISO 15552 and includes a magnet for CMSE reed and DMSE electronic sensors. While the cylinder body rates to 1.0 MPa, the integrated valve operates at 0.15-0.8 MPa, setting the practical working range for the assembled unit.
In the 32mm bore class, it provides 402N push and 345N pull force at 0.5 MPa. The manifold connects the valve to the cylinder using O8xO5 PU tubing, and the valve port (1/4) differs from the cylinder port (1/8). Factory-set to retract when energised, the valve can be repositioned to extend when energised, and the 5/2 pilot design holds position pneumatically without springs.

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 SAIF32X125S-08E Is Used
Decentralized Assembly Stations
Eliminates remote valve plumbing by driving the 32mm cylinder directly from an AC24V signal, saving panel space across large machine grids.
Compact Material Handling
Provides 402N push force at 0.5 MPa for diverters and gates, using the built-in 4M210-08 valve to achieve rapid 5 cycle/sec switching.
Retrofitted Automation Lines
Simplifies machine upgrades by replacing standalone cylinders and remote valves with a single ISO 15552 interchangeable unit that controls itself.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF32X125S-08E the Right Choice?
Choose this 32mm bore if your load requires around 402N of push force at 0.5 MPa; step up to the 40mm bore if you need 628N. This self-valved unit is ideal for decentralized stations where running separate valve tubing would consume excessive panel space. For load-holding applications, note that the 5/2 valve routes air but does not lock the piston; consider the SAIL series for mechanical locking needs. When ordering a replacement, verify the 125mm stroke, 1/8 cylinder port, 1/4 valve port, AC24V terminal coil, PT thread, and the -S magnet requirement.
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 SAIF32X125S-08E FAQ
The 32mm bore generates 402N push and 345N pull force at 0.5 MPa. The integrated 4M210-08 5/2 valve provides an effective area of 16.0 mm2 (Cv 0.89) with a maximum frequency of 5 cycles per second.
Yes, the factory setting retracts the rod when the AC24V coil is energised, but you can reposition the valve to extend-when-energised. The built-in valve eliminates the need for a separate remote valve, reducing tubing and panel space for decentralized installations.
