Airtac SAIF Series Standard Cylinder with Valve SAIF80X350-10A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF80X350-10A is a genuine double-acting ISO 15552 cylinder with a Ø80mm bore, 350mm 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 SAIF80X350-10A
The AirTAC SAIF80X350-10A is a double-acting ISO 15552 profile cylinder equipped with a built-in 4M310-10 5/2 solenoid valve. This integrated manifold block eliminates the need for a separate remote valve, reducing plumbing and panel space for decentralized machine stations. Driven by an AC220V terminal connection coil drawing 3.5 VA, it responds in 0.05 s. The 4M310-10 valve provides a 30.0 mm2 orifice (Cv 1.68) and operates at 4 cycles per second.
Because the built-in valve operates at 0.15-0.8 MPa, the practical working pressure for the assembled SAIF unit is 0.15-0.8 MPa, even though the bare cylinder rates to 1.0 MPa. At 0.5 MPa, this 80 mm bore generates 2513 N of push force and 2268 N of pull force. The factory setting retracts the piston rod when the coil is energised, but you can reconfigure it to extend-when-energised by repositioning the valve. The manifold connects to the cylinder via PU tubing (O10 x O6.5), and the valve port is 3/8" (PT thread), which differs from the cylinder's 3/8" port.

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 SAIF80X350-10A Is Used
Decentralized Automation
Ideal for large-scale production lines where local valve control saves wiring and eliminates long air tubing runs to a central panel.
High-Force Clamping
Provides robust 2513 N clamping force at 0.5 MPa for heavy-duty machining and fixturing operations within a compact footprint.
Space-Constrained Handling
Fits into tight machine envelopes where a standard cylinder plus a remote valve manifold would exceed available mounting space.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF80X350-10A the Right Choice?
Choose this 80 mm bore if you need substantial thrust (2513 N push at 0.5 MPa); stepping down to a 63 mm bore drops the push force to 1559 N, while moving up to 100 mm yields 3927 N. A self-valved SAIF is ideal when running separate valve tubing across a large machine is costly or space-prohibitive. This model uses an AC220V terminal entry coil with PT threads and lacks a magnet, so position sensing is not available without adding an -S option. For any load-holding requirements, note that the 5/2 valve only routes air and is not a lock; consider the AirTAC SAIL lock cylinder instead. Because the 350 mm stroke creates leverage, ensure adequate side-load guidance to prevent rod wear.
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 SAIF80X350-10A FAQ
At 0.5 MPa, this 80 mm bore cylinder generates 2513 N of push force and 2268 N of pull force. The built-in 4M310-10 valve has a 30.0 mm2 orifice with a Cv of 1.68.
No, the integrated 4M310 5/2 valve switches the cylinder directly from one AC220V coil signal. By default, the rod retracts when the coil is energised, but it can be reconfigured to extend-when-energised by repositioning the valve.
