Airtac SAIF Series Standard Cylinder with Valve SAIF100X150-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF100X150-08A is a genuine double-acting ISO 15552 cylinder with a Ø100mm bore, 150mm 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 SAIF100X150-08A
The AirTAC SAIF100X150-08A is a double-acting ISO 15552 profile cylinder equipped with a built-in 4M310-08 5/2 solenoid valve. This specific SKU features a 1.4 Cv flow rate, an AC220V terminal coil consuming 3.5 VA, and a carbon steel piston rod. Because the cylinder body rates to 1.0 MPa but the integrated valve operates at 0.15-0.8 MPa, the practical working range for this assembled unit is 0.15-0.8 MPa. The 100mm bore generates 3927N of push force at 0.5 MPa, making it suited for heavy-duty actuation.
By integrating the valve directly onto the manifold block, this unit eliminates remote plumbing and saves panel space for decentralized machine stations. The manifold connects to the cylinder using O10 x O6.5 PU tubing, and the valve port (1/4) differs from the main cylinder port (1/2). From the factory setting, the piston rod retracts when the coil is energised; you can reposition the valve to extend-when-energised if the logic requires it.

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)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 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 SAIF100X150-08A Is Used
Decentralized Heavy Manufacturing
Ideal for large assembly lines where routing air to remote valves is costly. The integrated 4M310 valve drives the 3927N push force locally from a single AC220V signal.
Space-Constrained Pressing
Delivers high clamping force in tight machine footprints. The manifold block removes the need for external valve mounting, keeping the envelope compact.
Automated Material Handling
Suitable for heavy payload shifting at 30-800 mm/s. The terminal electrical entry simplifies wiring across multiple decentralized stations.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF100X150-08A the Right Choice?
Select this 100mm bore model when an application requires substantial thrust—stepping down to an 80mm bore drops the 0.5 MPa push force to 2513N, while this 100mm unit hits 3927N. A self-valved SAIF is highly advantageous over a separate cylinder and remote valve when floor space is tight and running long tubing lines is costly. To order a replacement, match the 100mm bore, 150mm stroke, 1/2 cylinder port, 1/4 valve port, AC220V voltage, terminal entry, PT thread, and no magnet (-S).
Remember that the built-in 5/2 valve routes air but does not lock the load; if your machine requires true position holding without live pressure, consider the AirTAC SAIL lock cylinder instead.
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 SAIF100X150-08A FAQ
The 100mm bore cylinder provides 3927N of push force and 3681N of pull force at 0.5 MPa. The built-in 4M310-08 5/2 valve has a 25.0 mm2 orifice with a 1.40 Cv flow rate.
The integrated 4M310 valve is a 5/2 pilot-operated design that holds position via air pressure, not a spring. By default, the rod retracts when the AC220V coil is energised, but you can reposition the valve to extend-when-energised. No separate remote valve is needed.
