Airtac SAIF Series Standard Cylinder with Valve SAIF100X175S-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF100X175S-08B is a genuine double-acting ISO 15552 cylinder with a Ø100mm bore, 175mm 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 SAIF100X175S-08B
The AirTAC SAIF100X175S-08B is a double-acting ISO 15552 profile cylinder equipped with a built-in 4M310-08 5/2 solenoid valve, delivering a Cv of 1.40 and a 25.0 mm2 effective area. Driven by a DC24V terminal coil drawing 3.0 W, it integrates switching directly on the actuator to eliminate remote plumbing. The cylinder features a carbon steel piston rod and a PT tapered port thread.
Although the cylinder body rates to 1.0 MPa, the integrated valve operates at 0.15-0.8 MPa, establishing the practical working range for this assembled unit. It delivers 5497 N of push force at 0.7 MPa. The factory setting retracts the rod when the coil is energised, but you can reposition the valve to extend-when-energised. The -S magnet supports CMSE reed and DMSE electronic sensors for position feedback.

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 SAIF100X175S-08B Is Used
Decentralized Assembly Lines
Ideal for large automated machines where routing individual valve lines back to a central manifold is impractical, allowing each 100 mm station to control itself.
Heavy Clamping Fixtures
Provides 5497 N of clamping force at 0.7 MPa directly at the workpiece without needing external valve infrastructure, saving panel space.
Retrofitted Material Handling
Perfect for upgrading existing conveyors where adding a remote valve island is too expensive, utilizing the integrated 4M310 valve and DC24V terminal connection.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF100X175S-08B the Right Choice?
Choose this 100 mm bore when substantial thrust is required, stepping up from a 63 mm bore that yields 2182 N push at 0.5 MPa. The self-contained SAIF design excels in decentralized installations and space-tight machines where running separate valve tubing and panel wiring is costly. This specific SKU specifies a DC24V terminal electrical entry with a 1/4" valve port and 1/2" cylinder port.
Remember that the 5/2 valve routes air and cannot hold a load without live pressure; the variable air cushion only decelerates near stroke end. For secure load-holding, consider an AirTAC SAIL lock cylinder. When ordering a replacement, match the 100 mm bore, 175 mm stroke, 4M310-08 valve, DC24V voltage, terminal entry, PT thread, and -S magnet.
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 SAIF100X175S-08B FAQ
At 0.7 MPa, this 100 mm bore cylinder generates 5497 N of push force. The built-in 4M310-08 5/2 valve provides a 25.0 mm2 effective area with a Cv of 1.40, supporting a maximum frequency of 4 cycles per second.
Yes, the factory setting retracts the rod when the DC24V coil is energised, but you can reposition the valve to extend-when-energised. The built-in valve eliminates the need for a separate remote valve, reducing tubing, panel space, and wiring complexity for decentralized installations.
