Airtac SAIF Series Standard Cylinder with Valve SAIF100X150-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF100X150-08B 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 SAIF100X150-08B
The AirTAC SAIF100X150-08B is a double-acting ISO 15552 profile cylinder equipped with an integrated 4M310-08 5/2 solenoid valve, providing a Cv of 1.40 and a 25.0 mm2 effective area. Driven by a DC24V terminal entry coil consuming 3.0 W, it activates in 0.05 s or less. While the base cylinder rates to 1.0 MPa, the practical operating range for this self-valved assembly is 0.15-0.8 MPa, matching the internal piloted valve's limits.
This 100 mm bore unit generates 3927 N of push force at 0.5 MPa and reaches 7068 N at 0.9 MPa. The manifold connects to the cylinder via PU tubing (O10 x O6.5), and the valve port (1/4) is distinct from the 1/2 cylinder port. Factory-set to retract the rod when energised, the valve can be repositioned to extend on signal, eliminating the need for a remote valve and simplifying decentralized machine wiring.

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 SAIF100X150-08B Is Used
Decentralized Assembly Stations
Ideal for large machines with distributed stations, using a single DC24V signal to drive the 100 mm bore without remote valve banks.
High-Force Clamping
Provides 7068 N of push force at 0.9 MPa for securing heavy workpieces directly at the point of operation.
Retrofit Automation
Drops into existing ISO 15552 mounting interfaces, replacing standard cylinders to cut panel space and plumbing complexity.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF100X150-08B the Right Choice?
Select this 100 mm bore model when your application requires high thrust, as it delivers 3927 N push at 0.5 MPa. If you need less force and want a smaller envelope, stepping down to an 80 mm bore yields 2513 N push at 0.5 MPa. The SAIF100X150-08B is ideal for space-tight machines where running separate valve tubing is costly, as one DC24V coil signal directly controls the cylinder. For replacements, verify the 150 mm stroke, 1/2 cylinder port, 1/4 valve port, DC24V voltage, terminal entry, PT thread, and standard carbon steel rod. Since this unit relies on a 5/2 valve routing air, it will not hold a load without live pressure; for true mechanical locking, consider the SAIL or BSAI series. For any stroke at or above 300 mm, ensure external guides are used to manage side loads.
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 SAIF100X150-08B FAQ
At 0.5 MPa operating pressure, the 100 mm bore provides 3927 N of push force and 3681 N of pull force. At 0.9 MPa, the push force increases to 7068 N.
Yes. The factory setting retracts the piston rod when the DC24V coil is energised, but you can reposition the 4M310-08 5/2 valve to extend-when-energised. This eliminates the need for a separate remote valve.
