Airtac SAIF Series Standard Cylinder with Valve SAIF100X125S-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF100X125S-08B is a genuine double-acting ISO 15552 cylinder with a Ø100mm bore, 125mm 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 SAIF100X125S-08B
The AirTAC SAIF100X125S-08B is a double-acting ISO 15552 profile cylinder featuring an integrated 4M310-08 5/2 solenoid valve. This specific SKU is configured with a PT1/4 valve port, a DC24V terminal electrical entry, and a -S magnet for CMSE reed and DMSE electronic sensors. The built-in valve provides an effective flow area of 25.0 mm2 (Cv 1.40) and cycles up to 4 times per second. Because the cylinder body rates to 1.0 MPa but the internal pilot valve operates at 0.15-0.8 MPa, the practical working pressure for this assembled unit is 0.15-0.8 MPa.
Delivering 7068N of push force at 0.9 MPa, this 100mm bore unit eliminates the need for a separate remote valve, saving panel space and tubing. The manifold connects to the cylinder using O10 x O6.5 PU tubing, and the cylinder itself has a 1/2 port. From the factory, the piston rod retracts when the coil is energised, but you can reposition the valve to extend when energised. The standard carbon steel rod and extruded aluminum barrel ensure robust performance without requiring lubrication.

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 SAIF100X125S-08B Is Used
Decentralized Assembly Lines
Eliminates central valve islands by mounting the 4M310-08 valve directly on the cylinder, reducing plumbing complexity across large factory layouts.
High-Force Clamping
Provides 7068N of push force at 0.9 MPa for securing heavy workpieces during machining, utilizing a single DC24V coil signal.
Retrofit Automation
Ideal for upgrading older machines where adding external pneumatic tubing is impractical, offering self-switching with PT1/4 valve ports.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF100X125S-08B the Right Choice?
Select this 100mm bore model when an application requires substantial thrust, such as 7068N at 0.9 MPa, and stepping down to an 80mm bore (4523N at 0.9 MPa) would be insufficient. The self-valved SAIF design is ideal for decentralized machine stations where running individual valve tubing back to a central manifold is costly or space-prohibitive. A single DC24V terminal connection drives the cylinder directly. This unit includes a -S magnet for position sensing with AirTAC CMSE or DMSE switches.
When replacing, verify the 100mm bore, 125mm stroke, 4M310-08 valve with PT1/4 thread, DC24V voltage, terminal entry, and magnet. Note that the built-in 5/2 valve routes air and holds its position via internal pilot pressure, but it does not lock the load mechanically; for secure load-holding during air loss, consider the SAIL lock or BSAI clamp-lock series. Since the stroke is 125mm, side loads should be minimized through proper guide rails to prevent rod wear.
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 SAIF100X125S-08B FAQ
At 0.9 MPa, the 100mm bore generates 7068N of push force and 3681N of pull force. While the cylinder body rates to 1.0 MPa, the built-in 4M310-08 valve limits the practical operating pressure range to 0.15-0.8 MPa.
The integrated 5/2 solenoid valve holds its position via internal pilot pressure, not a spring. By factory default, energising the DC24V coil retracts the rod, but you can reposition the valve to extend-when-energised. No separate remote valve is needed.
