About the Airtac SAIF Series Standard Cylinder with Valve SAIF80X250-10A
The AirTAC SAIF80X250-10A is a double-acting ISO 15552 profile cylinder featuring an integrated 4M310-10 5/2 solenoid valve. This specific configuration pairs an 80mm bore with a 250mm stroke, utilizing a PT3/8 cylinder port and a 3/8 valve port. The built-in valve provides an effective flow area of 30.0 mm2 (Cv 1.68) and handles up to 4 cycles per second. Driven by an AC220V terminal entry coil drawing 3.5 VA, it activates in 0.05s or less with an IP65 rating.
Because the cylinder body rates to 1.0 MPa but the internal piloted 5/2 valve operates at 0.15-0.8 MPa, the practical working range for this assembled unit is 0.15-0.8 MPa. The manifold connects to the cylinder via O10xO6.5 PU tubing. Factory set to retract the rod when energized, the valve can be repositioned to extend on signal. It delivers 2513N of push force at 0.5 MPa, utilizing a carbon steel piston rod.

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 (Ø80mm)

| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 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 SAIF80X250-10A Is Used
Decentralized Machine Stations
Ideal for large assembly lines where running individual valve tubing back to a central panel is costly, letting each 80mm bore actuator switch itself locally.
High-Force Clamping Fixtures
Delivers 2513N of push force at 0.5 MPa directly at the workpiece, providing robust clamping for heavy machining operations without external valves.
Space-Constrained Retrofits
Perfect for upgrading older pneumatics where electrical panel space is limited, requiring only a single AC220V signal to drive the integrated 4M310 valve.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF80X250-10A the Right Choice?
Choose this 80mm self-valved unit when a decentralized station requires substantial thrust without routing long air lines to a remote valve island. If your application requires less force, stepping down to a 63mm bore yields 1559N of push at 0.5 MPa while retaining the 4M310 valve platform; stepping up to 100mm provides 3927N. This SAIF model eliminates separate valve plumbing and saves panel space, switching directly from one coil signal.
For stroke lengths at or above 300mm, guide the load to prevent excessive side loading on the rod. Remember that the 5/2 valve routes air but does not lock the load mechanically; if you need true position holding without live pressure, consider the SAIL lock variant. To replace this unit, match the 80mm bore, 250mm stroke, 3/8 valve port, AC220V terminal coil, PT thread, and standard carbon steel rod.
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 SAIF80X250-10A FAQ
At 0.5 MPa, this 80mm bore cylinder generates 2513N of push force and 2268N of pull force. The integrated 4M310-10 valve has an effective area of 30.0 mm2 (Cv 1.68) to handle the required air volume.
No, the integrated 5/2 valve switches the cylinder directly from the AC220V coil signal. By factory default, the piston rod retracts when the coil is energized, but you can reposition the valve to extend-when-energized if needed.
