Airtac SAIF Series Standard Cylinder with Valve SAIF100X225S-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF100X225S-08B is a genuine double-acting ISO 15552 cylinder with a Ø100mm bore, 225mm stroke and a built-in 4M310-08 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 SAIF100X225S-08B
The AirTAC SAIF100X225S-08B is a double-acting ISO 15552 profile cylinder equipped with a built-in 4M310-08 5/2 solenoid valve, delivering a Cv of 1.40 and a 25.0 mm2 effective orifice. Driven by a DC24V terminal entry coil drawing 3.0 W, it achieves IP65 protection and a 0.05 s activation time. The integrated manifold uses PU tubing (O10 x O6.5) to link the valve block to the cylinder, meaning the valve port (1/4) differs from the cylinder port (1/2). The assembled unit operates safely within 0.15-0.8 MPa, as the 4M310 valve limits the base cylinder's 1.0 MPa capacity.
Providing 3927 N of push force at 0.5 MPa and peaking at 801 kgf at 1.0 MPa, this 100 mm bore actuator includes a -S magnet for precise position sensing with AirTAC CMSE reed and DMSE electronic switches. Factory-set to retract the piston rod when the coil is energised, the valve can be physically repositioned to extend-when-energised. By switching itself from a single electrical signal, this unit eliminates remote valves, reduces panel plumbing, and excels in decentralized machine stations.

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 (Ø100mm)

| 0.7 MPa | 5498 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 SAIF100X225S-08B Is Used
Decentralized Automation Stations
Ideal for large assembly lines needing heavy push force without running long air lines to a central panel.
Compact Machining Cells
Saves valuable panel space by mounting the 4M310 valve directly on the profile cylinder.
Retrofit & Upgrades
Simplifies machine upgrades by replacing separate cylinder and valve setups with a single DC24V unit.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF100X225S-08B the Right Choice?
Choose this 100 mm bore SAIF when your application requires heavy thrust beyond the 2513 N push force of the neighbouring 80 mm bore at 0.5 MPa. The self-valved architecture is ideal for decentralized stations where routing air lines to a remote manifold is costly or space-prohibitive. It includes a -S magnet for CMSE/DMSE sensors and uses a PT tapered port thread. If your process loses air pressure, the 5/2 valve routes air but does not lock the load—consider an AirTAC SAIL pneumatic lock or BSAI clamp-lock for secure holding. Replacement requires matching the 100 mm bore, 225 mm stroke, 1/4 valve port, DC24V voltage, terminal entry, PT thread, and -S magnet.
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 SAIF100X225S-08B FAQ
The 100 mm bore cylinder generates 3927 N push force at 0.5 MPa and 5497 N at 0.7 MPa. The integrated 4M310-08 5/2 valve provides an effective area of 25.0 mm2 (Cv 1.40) with a maximum frequency of 4 cycles per second.
Yes, the factory setting retracts the rod when the DC24V coil is energised, but you can reposition the valve to extend-when-energised. The built-in 5/2 valve eliminates the need for a separate remote valve, reducing plumbing and panel space for decentralized installations.
