The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF100X250-08B is a genuine double-acting ISO 15552 cylinder with a Ø100mm bore, 250mm 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 SAIF100X250-08B is a double-acting ISO 15552 profile cylinder featuring an integrated 4M310-08 5/2 solenoid valve. This specific configuration pairs a 100mm bore with a DC24V terminal coil, consuming just 3.0W while achieving a rapid 0.05s activation time. The built-in valve provides an effective flow rate of 25.0mm2 (Cv 1.40) and operates at 4 cycles per second. Because the manifold routes air via a PU tube (O10 x O6.5), the valve port (1/4) differs from the cylinder port (1/2). The base cylinder rates to 1.0MPa, but the practical SAIF working range is 0.15-0.8MPa.
This assembled unit generates 3927N of push force and 3681N of pull force at 0.5MPa. A key operational feature is the factory default setting: the piston rod retracts when the coil is energised. By physically repositioning the valve, you can reconfigure the action to extend-when-energised. This decentralized design eliminates the need for remote valves and extensive tubing, saving valuable panel space on large machines. The standard carbon steel rod and tapered PT threads ensure robust pneumatic connections.

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 remote valve banks by switching directly from a single DC24V signal, drastically reducing tubing runs across large automated machinery.
Leverages 3927N of push force at 0.5MPa to move heavy pallets or fixtures without needing an external 5/2 solenoid manifold.
Ideal for machine upgrades where adding a new valve island is impossible; the integrated 4M310-08 valve provides localized control.
Select this 100mm bore model when your application requires high thrust, such as the 3927N push force at 0.5MPa, and you want to avoid the plumbing of a separate remote valve. If your force requirements are lower, stepping down to the 80mm bore yields 2513N push at 0.5MPa, which might better suit lighter duties. The SAIF100X250-08B is ideal for decentralized stations where running valve tubing is costly or space-prohibitive. Ensure you match the DC24V terminal electrical entry and 1/4 valve port to your control scheme.
For load-holding applications, note that the built-in 5/2 valve routes air but does not mechanically lock the load; consider an AirTAC SAIL lock cylinder if the load must be held without live pressure. The 250mm stroke on this unit is under the 1500mm standard maximum, but you should still account for potential side loads and use appropriate guide rails. When ordering replacements, verify the 100mm bore, 250mm stroke, 1/4 valve port, DC24V voltage, terminal entry, PT thread, and whether a magnet for CMSE or DMSE sensors is needed.
Quick checklist
At 0.5MPa, this 100mm bore cylinder provides 3927N of push force and 3681N of pull force. The integrated 4M310-08 5/2 valve has an effective area of 25.0mm2 (Cv 1.40) and supports up to 4 cycles per second.
The factory setting retracts the rod upon energization, but you can reconfigure it to extend-when-energised by repositioning the valve. Because the 5/2 valve is built-in and holds its position via internal pilot pressure, no separate remote valve is needed.
