Airtac SAIF Series Standard Cylinder with Valve SAIF63X225-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF63X225-08B is a genuine double-acting ISO 15552 cylinder with a Ø63mm 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 SAIF63X225-08B
The AirTAC SAIF63X225-08B is a double-acting ISO 15552 profile cylinder featuring a built-in 4M310-08 5/2 solenoid valve. This integrated manifold uses O10 x O6.5 PU tubing to link the valve block to the cylinder, eliminating the need for remote plumbing. The valve provides a 25.0 mm2 effective orifice (Cv 1.40) and operates at a maximum frequency of 4 cycles per second. Equipped with a DC24V terminal entry coil, it consumes 3.0 W, features IP65 protection, and activates in 0.05 seconds or less.
Because the cylinder body rates to 1.0 MPa but the built-in valve operates from 0.15 to 0.8 MPa, the practical working pressure range for the assembled SAIF unit is 0.15-0.8 MPa. At 0.5 MPa, this 63 mm bore generates 1559 N of push force and 1402 N 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 if your sequence demands it.

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 (Ø63mm)

| 0.5 MPa | 1559 N | 1402 N |
| 0.7 MPa | 2182 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 SAIF63X225-08B Is Used
Decentralized Machine Stations
Ideal for large machinery where routing air lines to a central valve island is inefficient. The integrated 4M310 valve lets one DC24V signal drive the actuator directly at the station.
Mid-Force Assembly Tooling
Provides 1559 N of push force at 0.5 MPa. Suited for clamping, pressing, or locating medium-weight components without needing a separate remote valve manifold.
Space-Constrained Retrofitting
The built-in valve and manifold block save panel space and plumbing. A strong drop-in upgrade for machines needing a 63 mm bore actuator with self-switching capability.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF63X225-08B the Right Choice?
Choose this self-valved SAIF63X225-08B when a decentralized machine layout makes running separate valve tubing costly or space-prohibitive. Stepping down to a 50 mm bore drops the 0.5 MPa push force to 982 N, while stepping up to an 80 mm bore raises it to 2513 N. The 225 mm stroke is well under the 1500 mm maximum standard stroke for this bore, so no non-standard surcharge applies. Remember that the 5/2 valve routes air but does not lock the load mechanically; for position holding, consider the SAIL lock or BSAI clamp-lock series. To match this exact unit for replacement, specify a 63 mm bore, 225 mm stroke, PT1/4 cylinder port, 4M310-08 valve port, DC24V voltage, terminal entry, and no sensor 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 SAIF63X225-08B FAQ
The 63 mm bore generates 1559 N of push force and 1402 N of pull force at 0.5 MPa. The integrated 4M310-08 5/2 valve has a 25.0 mm2 effective area (Cv 1.40) and a maximum operating frequency of 4 cycles per second.
No separate remote valve is needed. The unit integrates a 5/2 solenoid valve that switches the cylinder directly from a DC24V terminal connection. By factory default, the piston rod retracts when the coil is energised, but this can be reconfigured to extend-when-energised by repositioning the valve.
