The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF100X300S-08B is a genuine double-acting ISO 15552 cylinder with a Ø100mm bore, 300mm 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 SAIF100X300S-08B is a double-acting ISO 15552 profile cylinder equipped with a built-in 4M310-08 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. Driven by a DC24V terminal entry coil drawing 3.0 W, it activates in 0.05 s or less and features a carbon steel piston rod with a -S magnet for CMSE reed and DMSE electronic sensors.
While the bare cylinder body rates to 1.0 MPa, the practical operating range for this assembled SAIF unit is 0.15-0.8 MPa because the internal piloted 5/2 valve operates within that limit. The 4M310-08 valve provides a 25.0 mm2 effective area (Cv 1.40) and handles up to 4 cycles per second. Delivering 5497 N of push force at 0.7 MPa, the factory setting retracts the rod when the coil is energised, which can be reconfigured to extend-when-energised by 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).
Ideal for large-scale production lines where installing individual remote valves is impractical, allowing each heavy-duty station to control its own actuation locally.
Provides the robust push force needed for lifting, shifting, or positioning heavy workpieces directly at the machine tool without requiring external pneumatic plumbing.
Drops into existing ISO 15552 footprints to upgrade older setups, replacing a separate cylinder and valve assembly with a single, compact self-switching unit.
Choose this 100mm bore when you need heavy thrust that smaller neighbours cannot provide; for context, an 80mm bore yields 3518 N push at 0.5 MPa, whereas this 100mm unit delivers 3927 N at the same pressure. The self-valved architecture is ideal for large machines where running individual valve tubing back to a central manifold is costly. Because the stroke is 300mm, ensure adequate side-load guidance to prevent rod binding and premature seal wear. The 5/2 valve routes air but does not lock the load mechanically; for true position holding under pressure loss, consider the SAIL lock variant. When ordering a replacement, confirm the 300mm stroke, PT1/2 cylinder port, 4M310-08 valve port, DC24V terminal coil, PT thread, and -S magnet.
Quick checklist
At 0.7 MPa, this 100mm bore cylinder generates 5497 N of push force and 3681 N of pull force. The integrated 4M310-08 5/2 valve has an effective area of 25.0 mm2 (Cv 1.40) and supports a maximum frequency of 4 cycles per second.
No separate remote valve is needed; the cylinder switches itself from a single DC24V coil signal. By factory default, the piston rod retracts when the coil is energised, but you can reconfigure it to extend-when-energised simply by repositioning the integrated valve.
