Airtac SAIF Series Standard Cylinder with Valve SAIF100X225-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF100X225-08B 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 SAIF100X225-08B
The AirTAC SAIF100X225-08B is a double-acting ISO 15552 profile cylinder featuring an integrated 4M310-08 5/2 solenoid valve. This specific SKU is configured with a DC24V terminal electrical entry consuming 3.0 W, providing a robust Cv 1.40 flow rate. The built-in valve manifold connects to the cylinder via PU tubing (O10 x O6.5), meaning the 1/4" valve port and the 1/2" cylinder port serve distinct routing functions within the assembly.
Because the cylinder body rates to 1.0 MPa but the 4M310 valve operates at 0.15-0.8 MPa, the practical working range for this valved unit is 0.15-0.8 MPa. Delivering 3927 N of push force at 0.5 MPa, it switches itself from one coil signal, eliminating remote plumbing. The factory setting retracts the rod when the coil is energised, which you can reconfigure to extend-when-energised by repositioning the valve.

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 SAIF100X225-08B Is Used
Decentralized Heavy Machinery
Ideal for large automated lines where running individual valve tubing back to a central panel is costly. The integrated 4M310 valve handles heavy 3927 N loads directly at the station.
High-Force Clamping Stations
Provides robust clamping force in machining cells. The built-in valve ensures rapid local switching without pressure drops from long supply lines.
Space-Constrained Automation
Perfect for retrofitting into tight machine footprints where a separate valve island would not fit. The manifold block design keeps the envelope compact.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF100X225-08B the Right Choice?
Choose this 100 mm bore when you need heavy thrust (3927 N push at 0.5 MPa) that a smaller 80 mm bore (2513 N push) cannot provide, while stepping down makes sense if the 63 mm bore (1559 N) is sufficient. A self-valved SAIF excels in decentralized stations across large machines, saving panel space and tubing runs compared to a separate cylinder and remote valve. The 225 mm stroke is under the 1500 mm standard maximum, but always use a guide to prevent side-loading on longer strokes.
This assembly uses a DC24V terminal coil with PT threaded ports and no sensor magnet. Remember the 5/2 valve routes air but does not lock the load mechanically; if you need true load-holding without live pressure, consider the SAIL lock variant instead. For position feedback, a magnet (-S) must be specified to use CMSE reed or DMSE electronic sensors.
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 SAIF100X225-08B FAQ
The 100 mm bore generates 3927 N of push force and 3681 N of pull force at 0.5 MPa. The integrated 4M310-08 5/2 valve provides an effective area of 25.0 mm2 (Cv 1.40) with a maximum frequency of 4 cycles per second.
The integrated 4M310 valve allows the cylinder to switch itself from a single DC24V coil signal, drastically reducing plumbing and panel space for decentralized installations. By default, the rod retracts when the coil is energised, but this can be reconfigured to extend-when-energised by repositioning the valve.
