Airtac SAIF Series Standard Cylinder with Valve SAIF100X175-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF100X175-08A 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 SAIF100X175-08A
The AirTAC SAIF100X175-08A is a double-acting ISO 15552 profile cylinder featuring an integrated 4M310-08 5/2 solenoid valve. This specific configuration pairs a 1/2 inch cylinder port with a 1/4 inch valve port, utilizing a PU tube (O10 x O6.5) to bridge the manifold block. Driven by an AC220V terminal-entry coil consuming 3.5 VA, the assembly achieves a rapid 0.05s activation time while maintaining an IP65 rating.
Because the built-in valve operates at 0.15-0.8 MPa, this defines the practical working pressure range for the valved unit, even though the cylinder body itself rates to 1.0 MPa. At 0.5 MPa this 100mm bore generates 3927N of push force and 3681N of pull force. By default, the factory setting retracts the piston rod when the coil is energised, but you can reposition the valve to extend-when-energised. This self-contained design eliminates remote plumbing, saving panel space for decentralized machine stations.

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 SAIF100X175-08A Is Used
Decentralized Assembly Lines
Eliminates the need for long runs of valve tubing across large factory floors by integrating the 5/2 valve directly onto the cylinder.
High-Force Clamping Stations
Delivers 3927N of push force at 0.5 MPa for heavy-duty clamping tasks where panel space for separate valves is restricted.
Retrofits and Upgrades
Ideal for machine upgrades where adding a remote valve island is costly, utilizing the built-in AC220V terminal coil for direct control.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF100X175-08A the Right Choice?
Choose this 100mm bore SAIF when your application demands high thrust up to 3927N at 0.5 MPa. If you need less force, stepping down to an 80mm bore drops the push force to 2513N while reducing the physical envelope. The integrated 4M310-08 valve offers a 25.0mm2 effective area (Cv 1.40) and a maximum frequency of 4 cycles per second, making it suitable for high-flow actuation without requiring a separate manifold block.
When specifying a replacement, match the 175mm stroke, 1/2 inch cylinder port, 1/4 inch valve port, AC220V voltage, terminal entry, and PT thread type. Note that this unit does not include a magnet (-S) for CMSE or DMSE sensors. Remember that the built-in 5/2 valve routes air but does not hold the load without live pressure; for position holding, consider the SAIL lock series instead. Since the stroke is under 300mm, standard mounting suffices without auxiliary side-load guides.
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 SAIF100X175-08A FAQ
The 100mm bore cylinder generates 3927N push and 3681N pull force at 0.5 MPa. The integrated 4M310-08 5/2 valve provides an effective area of 25.0mm2 (Cv 1.40) with a maximum frequency of 4 cycles per second.
Yes. The factory default setting retracts the rod when the AC220V coil is energised, but you can reposition the valve on the manifold block to extend-when-energised. This self-contained design requires no separate remote valve.
