Airtac SAIF Series Standard Cylinder with Valve SAIF100X250-10B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF100X250-10B is a genuine double-acting ISO 15552 cylinder with a Ø100mm bore, 250mm stroke and a built-in 4M310-10 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 SAIF100X250-10B
The AirTAC SAIF100X250-10B is a double-acting ISO 15552 profile cylinder featuring an integrated 4M310-10 5/2 solenoid valve. This specific SKU is configured with a DC24V terminal electrical entry consuming 3.0 W, a PT3/8 valve port, and a larger PT1/2 cylinder port. The built-in valve provides an effective area of 30.0 mm2 (Cv 1.68) and handles up to 4 cycles per second. Because the valve manifold routes air internally via O10 x O6.5 PU tubing, you save panel space and eliminate remote plumbing.
While the bare cylinder body rates to 1.0 MPa, the practical operating pressure for this valved assembly is 0.15-0.8 MPa. In its factory setting, the piston rod retracts when the coil is energised, but you can reposition the valve to extend-when-energised if your sequence requires it. Delivering 3927 N of push force at 0.5 MPa, this 100mm bore unit provides massive output. The 5/2 valve holds its position via internal pilot pressure, not a spring, but note it will not lock the load safely without live air pressure.

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 SAIF100X250-10B Is Used
Heavy-Duty Forming Press
Leverages the 100mm bore's 3927 N push force at 0.5 MPa for stamping or clamping heavy components directly at the workstation.
Decentralized Automation Cell
Eliminates remote valve islands by using the built-in 4M310 valve, requiring only a DC24V signal and air supply to operate independently.
Large Machine Retrofit
Ideal for upgrading existing equipment where routing new pneumatic tubing from a central panel is cost-prohibitive or physically constrained.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF100X250-10B the Right Choice?
Select this 100mm bore model when your application demands high thrust that smaller bores cannot provide, such as heavy lifting or pressing. If you need less force, stepping down to the 80mm bore yields 2513 N push force at 0.5 MPa, which may suit lighter loads and reduce air consumption. Conversely, this SAIF100X250-10B is the maximum standard size for the series. The integrated valve approach is highly advantageous for decentralized stations across large machines, as it requires only a single DC24V electrical signal and a main air supply, bypassing the need to run long valve tubing back to a central manifold.
When replacing this unit, verify the 250mm stroke, PT1/2 cylinder port, 4M310-10 valve with PT3/8 port, DC24V voltage, terminal entry, and standard carbon steel rod. Because this cylinder lacks a magnet, position sensing requires adding one or external methods. Since the stroke is 250mm, ensure adequate side-load support and use appropriate guide rails to prevent rod binding. For applications requiring true load holding without air pressure, consider the AirTAC SAIL lock cylinder instead.
Quick checklist

Airtac SAIF Series Standard Cylinder with Valve SAIF100X250-10B FAQ
At 0.5 MPa operating pressure, this 100mm bore cylinder generates 3927 N of push force and 3681 N of pull force. The integrated 4M310-10 5/2 solenoid valve has an effective area of 30.0 mm2 (Cv 1.68) and supports a maximum frequency of 4 cycles per second.
No, the SAIF100X250-10B switches itself using the built-in 4M310 valve driven by a DC24V terminal coil (3.0 W, IP65). By factory default, the rod retracts when the coil is energised, but it can be reconfigured to extend-when-energised by repositioning the valve.
