Airtac SAIF Series Standard Cylinder with Valve SAIF100X225-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF100X225-08A is a genuine double-acting ISO 15552 cylinder with a Ø100mm bore, 225mm 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 SAIF100X225-08A
The AirTAC SAIF100X225-08A is a double-acting ISO 15552 profile cylinder featuring a built-in 4M310-08 5/2 solenoid valve. This specific SKU pairs a 100mm bore with a 1/4" valve port and an AC220V terminal coil connection, drawing 3.5 VA. 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. It delivers substantial thrust, pushing 3927N at 0.5 MPa.
By mounting the valve directly on a manifold block, this self-switching unit eliminates the need for a separate remote valve. The manifold connects to the cylinder using PU tubing (O10 x O6.5), while the cylinder itself uses a 1/2" port. From the factory, the piston rod retracts when the coil is energised, but you can reposition the valve to extend-when-energised. This decentralized design saves panel space and reduces plumbing across large machines.

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 SAIF100X225-08A Is Used
Decentralized Automation
Ideal for large-scale production lines where installing individual remote valves is impractical, allowing each station to control itself via a single AC220V signal.
High-Force Clamping
Provides robust push force (up to 7068N at 0.9 MPa) for securing heavy workpieces during machining, without needing external valve plumbing.
Space-Constrained Retrofits
Simplifies machine upgrades by integrating the 4M310 valve and cylinder into one assembly, drastically reducing the required panel and tubing space.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF100X225-08A the Right Choice?
Choose this 100mm bore when you need high force (3927N push at 0.5 MPa) in a decentralized layout where running separate valve tubing is costly. If you need less force, stepping down to the 80mm bore yields 2513N push at 0.5 MPa. This SAIF100X225-08A configuration specifies a 4M310-08 valve (Cv 1.40), AC220V voltage, terminal electrical entry, and PT threaded ports. The carbon steel rod meets standard requirements. When ordering a replacement, verify the 225mm stroke, 1/4" valve port, and lack of a magnet (-S).
Although 225mm is within the 1500mm maximum standard stroke, always ensure adequate guiding for the rod to prevent side-loading. Note that the built-in 5/2 valve routes air but does not lock the load; if you need true load holding, consider the SAIL lock variant 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 SAIF100X225-08A FAQ
The 100mm bore cylinder provides a push force of 3927N at 0.5 MPa and 5497N at 0.7 MPa. The integrated 4M310-08 5/2 valve has an effective area of 25.0 mm2 (Cv 1.40) and a max frequency of 4 cycles per second.
No, the 4M310 valve is built-in. It operates on AC220V (3.5 VA, IP65) with a 0.05s response time. The factory setting retracts the rod when energised, but repositioning the valve changes it to extend-when-energised.
