The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF100X125S-08A 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.
The AirTAC SAIF100X125S-08A is a double-acting ISO 15552 profile cylinder featuring an integrated 4M310-08 5/2 solenoid valve. This built-in valve provides a Cv of 1.40 and operates at a maximum frequency of 4 cycles per second. Equipped with a standard carbon steel rod and a magnet for CMSE reed or DMSE electronic sensors, it generates a substantial 3927N push force at 0.5 MPa. Driven by an AC220V terminal entry coil consuming 3.5 VA, the unit activates in 0.05 seconds.
Because the cylinder body rates to 1.0 MPa but the internal pilot valve operates from 0.15-0.8 MPa, the practical working range for this assembled SAIF unit is 0.15-0.8 MPa. The manifold connects the valve to the cylinder using PU tubing (O10 x O6.5). By default, the factory setting retracts the piston rod when the coil is energised; this can be reconfigured to extend-when-energised by simply repositioning the valve.

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.

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).
Eliminates long tubing runs from a central manifold by switching directly at the cylinder, saving panel space and simplifying wiring across large factory layouts.
Leverages the 3927N push force at 0.5 MPa to drive heavy-duty pressing, clamping, and joining operations within space-constrained machinery.
Ideal for upgrading existing lines where routing new valve tubing is costly or impractical, providing an all-in-one actuator driven by a single AC220V signal.
Choose this 100mm bore when your application requires high thrust, such as the 3927N push force at 0.5 MPa or 5497N at 0.7 MPa. If your force requirements are lower, stepping down to an 80mm bore yields 2513N at 0.5 MPa, which saves space and air consumption. The self-valved SAIF design eliminates the need for a separate remote valve, drastically reducing plumbing and panel space for decentralized stations across large machines.
When specifying this model, verify your requirements for a 1/2 inch cylinder port and a 1/4 inch valve port. Remember that the 5/2 valve routes air and is not a lock; the air cushion only decelerates the load near stroke end. If you need true load holding without live pressure, consider the SAIL lock or BSAI clamp-lock series instead. To replace this unit, match the 100mm bore, 125mm stroke, 1/4 inch valve port, AC220V voltage, terminal entry, PT thread, and the -S magnet.
Quick checklist
The 100mm bore generates a push force of 3927N at 0.5 MPa and 5497N at 0.7 MPa. The built-in 4M310-08 5/2 valve has an effective area of 25.0 mm2 (Cv 1.40).
No, the 5/2 valve routes air but does not lock the load; the air cushion only decelerates near stroke end. By default, the rod retracts when the coil is energised, but it can be reconfigured to extend-when-energised. For true position holding without live pressure, use the SAIL or BSAI series.
