Airtac SAIF Series Standard Cylinder with Valve SAIF80X50-10A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF80X50-10A is a genuine double-acting ISO 15552 cylinder with a Ø80mm bore, 50mm 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 SAIF80X50-10A
The AirTAC SAIF80X50-10A is a double-acting ISO 15552 profile cylinder engineered with a built-in 4M310-10 5/2 solenoid valve, delivering a Cv of 1.68 and a 30 mm2 effective orifice. Driven by an AC220V terminal entry coil consuming 3.5 VA, it activates in 0.05 s or less. While the bare cylinder rates to 1.0 MPa, the integrated valve operates at 0.15-0.8 MPa, establishing the practical working range for this assembled unit. It generates 2513 N of push force at 0.5 MPa.
By switching itself from a single coil signal, this unit eliminates the need for a remote valve, reducing plumbing and panel space for decentralized machine stations. The manifold connects to the cylinder via PU tubing (O10 x O6.5). Factory-set to retract the piston rod when energised, the valve can be repositioned to extend-when-energised if your sequence requires 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 (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 SAIF80X50-10A Is Used
Decentralized Automation
Ideal for large machines with decentralized stations, eliminating long tubing runs by mounting the valve directly on the cylinder.
High-Force Clamping
Provides 2513 N of push force at 0.5 MPa for securing heavy workpieces during machining or welding operations.
Compact Panel Retrofits
Solves space constraints in electrical cabinet retrofits where running separate valve exhaust tubing is costly or impossible.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF80X50-10A the Right Choice?
Choose this 80 mm bore when you need substantial thrust (2513 N push at 0.5 MPa) but want to step down from the 100 mm bore (which yields 3927 N at 0.5 MPa) to save envelope space. The self-valved SAIF architecture beats a separate cylinder and remote valve in space-tight machines, as it requires only one electrical signal to operate. Remember the 5/2 valve routes air and is not a lock; if you need true load-holding, look to the SAIL series.
When replacing, match the 50 mm stroke, PT3/8 cylinder port, 4M310-10 valve with a PT3/8 port thread, AC220V voltage, terminal entry, and confirm no magnet is needed. The standard carbon steel rod handles general industrial loads. Operating speed ranges from 30-800 mm/s.
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 SAIF80X50-10A FAQ
At 0.5 MPa operating pressure, this 80 mm bore cylinder generates 2513 N of push force and 2268 N of pull force. The integrated 4M310-10 5/2 valve provides an effective flow area of 30 mm2 (Cv 1.68).
No, the built-in 4M310-10 5/2 valve switches the cylinder directly from the AC220V coil signal. By default, the rod retracts when energised, but you can reposition the valve to extend-when-energised if needed.
