Airtac SAIF Series Standard Cylinder with Valve SAIF80X450-10A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF80X450-10A is a genuine double-acting ISO 15552 cylinder with a Ø80mm bore, 450mm 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 SAIF80X450-10A
The AirTAC SAIF80X450-10A is a double-acting profile cylinder with a built-in 4M310-10 5/2 solenoid valve, delivering a Cv of 1.68 and a 30 mm2 orifice. Bundling the actuator and valve eliminates remote plumbing, saving panel space for decentralized machine stations. Driven by an AC220V terminal-entry coil drawing 3.5 VA, it activates in 0.05 s with an IP65 rating. The integrated valve routes air through a PU tube (O10 x O6.5) to the PT3/8 cylinder ports.
While the bare carbon-steel rod cylinder rates to 1.0 MPa, the internal pilot valve operates at 0.15-0.8 MPa, setting the practical working range for this assembly. It generates 2513 N of push force at 0.5 MPa and 4523 N at 0.9 MPa. The factory setting retracts the piston rod when the coil is energised, but you can reposition the valve to extend-when-energised. This 5/2 valve holds position via pilot pressure, not a spring.

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)
| Pressure | Push force | Pull force |
|---|---|---|
| 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 SAIF80X450-10A Is Used
Decentralized Automation
Ideal for large machines with distributed stations, driving the 450mm stroke directly from one AC220V signal without running long valve tubing back to a central manifold.
Long-Travel Handling
Provides 2513 N push force at 0.5 MPa for moving heavy pallets or lifting fixtures, using external guides to manage side-load across the extended stroke.
Retrofit & Upgrades
Simplifies machine upgrades by replacing a bare ISO 15552 cylinder with a self-switching unit, adding 4M310 valve control without needing extra panel space.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF80X450-10A the Right Choice?
Choose this 80mm bore when a 63mm bore falls short on thrust, offering 2513 N push versus the 63mm's 1559 N at 0.5 MPa. The 450mm stroke suits long-travel handling, but at this length you must account for rod side-load and use external guide rails to prevent binding. The 4M310 valve hits a 4 cycle/sec max frequency, matching the 30-800 mm/s speed range. This self-valved unit beats a separate cylinder plus remote valve by cutting tubing runs and wiring to a single AC220V terminal signal. For exact replacements, match the 80mm bore, 450mm stroke, 3/8 valve port, AC220V terminal coil, PT threads, and no magnet. If your process needs to hold a load without live pressure, use a SAIL lock cylinder instead, as this 5/2 valve and its air cushions are not brakes.
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 SAIF80X450-10A FAQ
The 80mm bore generates 2513 N push and 2268 N pull at 0.5 MPa, reaching 4523 N push at 0.9 MPa. The built-in 4M310-10 valve has a 30 mm2 orifice with a Cv of 1.68.
No, the built-in 4M310 5/2 valve switches the cylinder directly from the AC220V terminal coil. By default, the rod retracts when energised, but you can reposition the valve to extend-when-energised.
