Airtac SAIF Series Standard Cylinder with Valve SAIF80X160-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF80X160-08A is a genuine double-acting ISO 15552 cylinder with a Ø80mm bore, 160mm 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 SAIF80X160-08A
The AirTAC SAIF80X160-08A is a double-acting ISO 15552 profile cylinder featuring an integrated 4M310-08 5/2 solenoid valve. The built-in valve provides a 25.0 mm2 effective area (Cv 1.40) and operates at 4 cycles per second. Driven by an AC220V terminal entry coil consuming 3.5 VA, it activates in 0.05 s or less. Because the manifold relies on the 4M310 valve, the practical operating pressure for the assembled unit is 0.15-0.8 MPa, even though the cylinder body itself rates to 1.0 MPa. This 80 mm bore generates 2513 N of push force at 0.5 MPa.
The manifold connects the valve to the cylinder using PU tubing (O10 x O6.5). Factory configured to retract the rod when the coil is energised, the valve can be repositioned to extend on signal instead. This self-switching design eliminates the need for a remote valve, reducing panel space and tubing runs for decentralized machine stations. The unit uses a carbon steel piston rod and PT tapered threads.

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)

| 0.7 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 SAIF80X160-08A Is Used
Decentralized Assembly Lines
Eliminates the need for long tubing runs back to a central manifold, using a single AC220V signal to drive heavy 2513 N clamping operations directly at the workstation.
Space-Constrained Machinery
The integrated 4M310-08 valve saves valuable panel space while providing a Cv of 1.40 to cycle the 80 mm bore efficiently within tight machine envelopes.
Retrofit Automation Upgrades
Ideal for upgrading existing ISO 15552 installations where adding external valve plumbing is costly, offering self-contained 0.15-0.8 MPa operation with a terminal electrical connection.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF80X160-08A the Right Choice?
Choose this 80 mm bore when a machine requires substantial thrust, such as the 2513 N push force at 0.5 MPa, but has limited panel space for a separate directional valve. If your application needs less force, stepping down to a 63 mm bore yields 1559 N at 0.5 MPa. This SAIF model is ideal for decentralized stations because one AC220V terminal coil signal directly controls the cylinder, minimizing plumbing. The valve port is 1/4 inch (code 08) while the cylinder port is 3/8 inch. Remember that the 5/2 valve routes air and is not a lock; the air cushion only decelerates the piston near stroke ends. For load-holding requirements, consider an SAIL lock cylinder. When replacing, match the 160 mm stroke, 1/4 inch valve port, AC220V voltage, terminal entry, PT threads, and standard carbon steel rod.
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 SAIF80X160-08A FAQ
The 80 mm bore generates 2513 N of push force and 2268 N of pull force at 0.5 MPa. The integrated 4M310-08 5/2 valve has an effective area of 25.0 mm2 (Cv 1.40) and supports a maximum frequency of 4 cycles per second.
No separate remote valve is needed; the integrated 4M310 valve switches the cylinder directly from the AC220V coil signal. By factory default, the piston rod retracts when the coil is energised, but this can be reconfigured to extend-when-energised by repositioning the valve.
