Airtac SAIF Series Standard Cylinder with Valve SAIF80X300-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF80X300-08A is a genuine double-acting ISO 15552 cylinder with a Ø80mm bore, 300mm stroke and a built-in 4M310-08 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 SAIF80X300-08A
The AirTAC SAIF80X300-08A is a double-acting ISO 15552 profile cylinder with a built-in 4M310-08 5/2 solenoid valve. Delivering a Cv of 1.40 and a 25.0 mm2 effective area, the integrated valve manifold switches the bore directly from a single AC220V terminal coil signal. The cylinder body features an extruded aluminum barrel with a carbon steel piston rod, generating 2513 N of push force at 0.5 MPa. Because the valve operates at 0.15-0.8 MPa, this sets the practical working pressure range for the assembled SAIF unit, even though the cylinder body itself rates to 1.0 MPa.
By self-switching at 4 cycles per second, this unit eliminates remote plumbing and saves panel space for decentralized installations. The manifold connects to the cylinder using O10 x O6.5 PU tubing, and the valve port (1/4) differs from the cylinder port (3/8). From the factory, the piston rod retracts when the coil is energised, but you can reposition the valve to extend-when-energised. The AC coil consumes 3.5 VA, features IP65 protection, and activates in 0.05 s or less.

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 SAIF80X300-08A Is Used
Decentralized Stations
Eliminates the need for a remote valve island, reducing tubing runs across large factory layouts.
Space-Tight Machines
The integrated manifold saves valuable panel and footprint space in compact assembly equipment.
Retrofit Installations
Ideal for upgrading older machines where running new pneumatic valve tubing is costly or difficult.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF80X300-08A the Right Choice?
Choose this 80 mm bore when a 63 mm bore (providing 1559 N push at 0.5 MPa) is insufficient, but a 100 mm bore (3927 N) is oversized. The 300 mm stroke is well within the 1500 mm standard maximum, but at this length you should account for potential side-load and use a guide to prevent rod binding. The 4M310-08 valve provides ample flow for the bore, while the AC220V terminal connection offers straightforward wiring. Because the 5/2 valve holds position via internal pilot pressure and the air cushion only decelerates near stroke end, this unit does not lock or hold loads without live pressure; for true load-holding, consider the SAIL lock cylinder. To replace this unit, match the 80 mm bore, 300 mm stroke, 1/4 valve port, AC220V voltage, terminal entry, PT thread, and no magnet (-S omitted).
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 SAIF80X300-08A FAQ
The 80 mm bore generates 2513 N of push force and 2268 N of pull force at 0.5 MPa. The built-in 4M310-08 valve provides a 25.0 mm2 effective area (Cv 1.40) to drive the cylinder.
The integrated 5/2 valve routes air to switch the cylinder from a single AC220V coil signal, meaning no separate valve is needed. By default, the rod retracts when energised, but it can be reconfigured to extend. The valve and air cushion do not lock the load; live pressure is required to hold position.
