Airtac SAIF Series Standard Cylinder with Valve SAIF80X250-10B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF80X250-10B is a genuine double-acting ISO 15552 cylinder with a Ø80mm bore, 250mm stroke and a built-in 4M310-10 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 SAIF80X250-10B
The AirTAC SAIF80X250-10B is a double-acting ISO 15552 profile cylinder featuring an integrated 4M310-10 5/2 solenoid valve. This specific SKU is configured with a DC24V terminal electrical entry consuming 3.0 W, a PT3/8 cylinder port, and a 3/8 valve port yielding a 30.0 mm2 effective area (Cv 1.68). The carbon steel piston rod delivers a push force of 2513 N at 0.5 MPa. Because the manifold links the valve to the cylinder via O10 x O6.5 PU tubing, you eliminate remote plumbing and save panel space.
While the bare cylinder body rates to 1.0 MPa, the practical operating pressure for this assembled unit is 0.15-0.8 MPa due to the internal piloted valve limits. The factory setting retracts the rod when the coil is energised, but you can reposition the valve to extend-when-energised. It operates at speeds of 30-800 mm/s, and the 5/2 valve holds its position via pilot pressure, not a mechanical lock.

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 SAIF80X250-10B Is Used
Decentralized Automation
Eliminates the need for a remote valve island on large machines by switching directly from a single DC24V signal, drastically reducing tubing costs.
High-Force Clamping
Provides 2513 N of push force at 0.5 MPa directly at the workstation, ideal for securing heavy workpieces during machining operations.
Space-Constrained Retrofits
The built-in 4M310-10 valve manifold saves valuable panel space, making it perfect for upgrading older equipment where adding external valves is difficult.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF80X250-10B the Right Choice?
Choose this 80mm bore when you need high thrust (2513 N push at 0.5 MPa) in a decentralized station without routing long air lines to a main manifold. If your application requires less force, stepping down to a 63mm bore yields 1559 N push at 0.5 MPa; if you need more, the 100mm bore offers 3927 N. The integrated DC24V terminal coil switches in 0.05 s or less with IP65 protection, making it ideal for space-tight machinery. For stroke lengths of 250mm, ensure adequate guiding to prevent excessive side loading on the rod.
When replacing this unit, match the 80mm bore, 250mm stroke, 3/8 valve port, DC24V voltage, terminal entry, and PT thread. Note that the 5/2 valve routes air but does not lock the load mechanically; if you need true hold without live pressure, consider the SAIL lock variant. This SAIF model omits the magnet, so CMSE or DMSE sensors cannot be used unless specified.
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 SAIF80X250-10B FAQ
The built-in 4M310-10 valve has an effective area of 30.0 mm2 (Cv 1.68). The 80mm bore cylinder generates a push force of 2513 N and a pull force of 2268 N at 0.5 MPa.
Yes. The factory default retracts the rod when the DC24V coil is energised, but you can reposition the 5/2 valve on the manifold to extend-when-energised. The valve holds position via pilot pressure, not a spring.
