Airtac SAIF Series Standard Cylinder with Valve SAIF80X400-10A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF80X400-10A is a genuine double-acting ISO 15552 cylinder with a Ø80mm bore, 400mm 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 SAIF80X400-10A
The AirTAC SAIF80X400-10A is a double-acting profile cylinder dimensionally interchangeable per ISO 15552, featuring a built-in 4M310-10 5/2 solenoid valve. This integrated manifold block uses O10 x O6.5 PU tubing to connect the valve to the PT3/8 cylinder ports, eliminating the need for remote pneumatic plumbing. Delivering 2513N of push force at 0.5 MPa, it is driven by an AC220V terminal-entry coil consuming 3.5 VA with an IP65 rating. Because the valve operates at 0.15-0.8 MPa, this defines the practical working pressure range for the assembled unit, even though the bare cylinder rates to 1.0 MPa.
By default, the factory setting retracts the piston rod when the coil is energised, but you can reconfigure it to extend-when-energised simply by repositioning the valve. Operating at a maximum frequency of 4 cycles per second, this self-contained unit switches itself from one coil signal, making it ideal for decentralized stations across large machines where panel space and tubing runs are at a premium.

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 SAIF80X400-10A Is Used
Decentralized Machine Stations
Eliminates the need for a remote valve island on large machines by integrating the 4M310 valve directly onto the cylinder, drastically reducing pneumatic tubing and electrical wiring.
Heavy Assembly Presses
Provides 2513N of push force at 0.5 MPa for clamping and pressing tasks, while the 400mm stroke accommodates varying part sizes without manual adjustments.
Space-Constrained Retrofitting
Ideal for upgrading older machines where running new valve tubing back to a central panel is costly or physically impossible due to space constraints.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF80X400-10A the Right Choice?
Choose this 80mm bore when you need substantial thrust—stepping down to a 63mm bore reduces the 0.5 MPa push force to 1559N, while stepping up to a 100mm bore yields 3927N. The SAIF80X400-10A is specified with a 400mm stroke, a 4M310-10 valve (1/4" and 3/8" ports available), an AC220V terminal connection, and PT threading. Because the stroke is 400mm, you must account for side-load risks and ensure adequate guide support to prevent rod binding. If your application requires the cylinder to hold its load without live air pressure, note that the built-in 5/2 valve routes air but does not lock; for true load-holding, select a SAIL lock cylinder or BSAI clamp-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 SAIF80X400-10A FAQ
The built-in 4M310-10 valve has an effective area of 30.0 mm2 (Cv 1.68). The 80mm bore cylinder generates 2513N of push force and 2268N of pull force at 0.5 MPa, operating at speeds between 30-800 mm/s.
By factory default, the AC220V coil energizes to retract the piston rod. This behavior can be reconfigured to extend-when-energised by physically repositioning the 5/2 valve on the manifold block.
