Airtac SAIF Series Standard Cylinder with Valve SAIF32X125S-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF32X125S-08A 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-08A
The AirTAC SAIF32X125S-08A is a double-acting ISO 15552 profile cylinder featuring a built-in 4M210-08 5/2 solenoid valve. This integrated manifold design eliminates the need for a separate remote valve, drastically reducing plumbing and panel space for decentralized machine stations. Equipped with a position magnet (-S), it works seamlessly with AirTAC CMSE reed and DMSE electronic sensors. The AC220V terminal coil draws 3.5 VA, features IP65 protection, and activates in 0.05 seconds or less.
While the bare cylinder body rates to 1.0 MPa, the practical operating pressure for this assembled unit is 0.15-0.8 MPa due to the internal pilot valve limits. It delivers 402 N of push thrust and 345 N of pull thrust at 0.5 MPa. The manifold connects to the cylinder via O8 x O5 PU tubing, and the valve utilizes a 1/4" port, distinct from the cylinder's 1/8" port. Factory-set to retract the rod when energized, the valve can be repositioned to extend on signal if your sequence requires it.

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-08A Is Used
Decentralized Assembly Stations
Eliminates remote valve banks by switching locally via the AC220V terminal coil, saving panel space across large multi-station machines.
Compact Automation Retrofits
Ideal for upgrading existing lines where routing new pneumatic tubing to a central manifold is costly or physically constrained.
Position-Sensing Operations
The integrated -S magnet pairs with CMSE and DMSE switches to confirm mid-stroke or end-of-stroke positions in automated clamping.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF32X125S-08A the Right Choice?
Choose this 32mm bore when you need compact actuation delivering 402 N push force at 0.5 MPa; step up to a 40mm bore if your application requires 628 N. The self-valved SAIF architecture is optimal for space-tight machines or retrofits where running long valve tubing is costly, as one electrical signal directly drives the cylinder. This specific SKU specifies an AC220V terminal connection with PT threads.
When ordering a replacement, verify the 125mm stroke, 1/4" valve port, AC220V coil, terminal entry, and the -S magnet. Note that the built-in 5/2 valve routes air and is not a locking mechanism; the air cushions only decelerate the piston near stroke ends. For genuine load-holding requirements, consider the SAIL lock series instead.
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-08A FAQ
At 0.5 MPa, this 32mm bore cylinder provides 402 N of push force and 345 N of pull force. The integrated 4M210-08 5/2 valve has an effective area of 16.0 mm2 (Cv 0.89) and a maximum operating frequency of 5 cycles per second.
No, the 4M210-08 valve is built directly onto the cylinder manifold. It operates on a single AC220V electrical signal. By factory default, the piston rod retracts when the coil is energized, but you can reposition the valve to extend-when-energized if needed.
