Airtac SAIF Series Standard Cylinder with Valve SAIF100X175-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF100X175-08B 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 SAIF100X175-08B
The AirTAC SAIF100X175-08B is a double-acting ISO 15552 profile cylinder engineered with a built-in 4M310-08 5/2 solenoid valve. Driven by a DC24V terminal entry coil drawing 3.0 W, it achieves a 0.05 s activation time. The integrated valve provides a 25.0 mm2 effective area (Cv 1.40) and operates at 4 cycles per second. Because the valve manifold mounts directly using O10 x O6.5 PU tubing, it eliminates remote plumbing and saves panel space. The cylinder features a 1/2 inch PT port, while the valve utilizes a 1/4 inch port.
Although the cylinder body rates to 1.0 MPa, the practical operating range for this valved assembly is 0.15-0.8 MPa. It generates 3927 N of push force and 3681 N of pull force at 0.5 MPa. Factory configured to retract the rod when the coil is energized, the valve can be repositioned to extend on signal. The standard carbon steel rod and adjustable air cushions handle heavy loads, while the 5/2 valve routes air without locking the position.

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)

| 0.5 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 SAIF100X175-08B Is Used
Decentralized Automation
Ideal for large machines with decentralized stations, using the built-in valve to minimize pneumatic tubing and electrical wiring across the factory floor.
Heavy Material Handling
Provides robust push force for heavy material handling tasks, utilizing the 100 mm bore and integrated 4M310 valve for rapid localized switching.
Space-Constrained Retrofits
Perfect for retrofits where panel space is tight, mounting the 5/2 valve directly on the cylinder profile to eliminate the need for a remote manifold.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF100X175-08B the Right Choice?
Select this 100 mm bore model when an application demands high thrust, delivering 5497 N push force at 0.7 MPa. If your machine requires less force, stepping down to an 80 mm bore yields 2513 N push at 0.5 MPa. The self-valved SAIF design excels in decentralized stations where running separate valve tubing is costly, allowing one DC24V electrical signal to control the actuator directly. Remember the air cushion only decelerates near stroke ends; it does not hold the load without live pressure.
When replacing this unit, verify the 175 mm stroke, 1/4 inch valve port, 1/2 inch cylinder port, DC24V terminal coil, PT threads, and absence of a sensor magnet. The 4M310-08 valve supports speeds of 30-800 mm/s. For stroke lengths at or above 300 mm, always use a side-load guide to prevent rod damage.
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 SAIF100X175-08B FAQ
At 0.5 MPa, this 100 mm bore cylinder generates 3927 N of push force and 3681 N of pull force. The built-in 4M310-08 valve has an effective area of 25.0 mm2 (Cv 1.40).
It uses a DC24V terminal entry coil drawing 3.0 W. By factory default, the 5/2 valve retracts the rod when energized, but you can reposition the valve to extend on signal. No separate remote valve is needed.
