Airtac SAIF Series Standard Cylinder with Valve SAIF40X80S-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF40X80S-08A is a genuine double-acting ISO 15552 cylinder with a Ø40mm bore, 80mm stroke and a built-in 4M210-08 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 SAIF40X80S-08A
The AirTAC SAIF40X80S-08A is a double-acting ISO 15552 profile cylinder featuring an integrated 4M210-08 5/2 solenoid valve. This specific SKU is configured with a PT1/4 cylinder port, a 1/4 inch valve port, and an AC220V terminal electrical entry. The built-in valve delivers a 16.0 mm2 effective area (Cv 0.89) and switches up to 5 cycles per second. Because the cylinder body rates to 1.0 MPa but the internal pilot valve operates at 0.15-0.8 MPa, the practical working pressure for this assembled unit is 0.15-0.8 MPa. It generates 628 N of push force and 528 N of pull force at 0.5 MPa.
Equipped with a magnet (-S), this model supports AirTAC CMSE reed and DMSE electronic solid-state sensors for precise position detection. The manifold connects to the cylinder via O8 x O5 PU tubing, meaning the valve port differs from the cylinder port. Factory-set to retract the rod when the coil is energized, the valve can be repositioned to extend-when-energized. By driving the cylinder directly from one coil signal, it eliminates remote plumbing and saves panel space for decentralized installations.

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 (Ø40mm)

|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 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 SAIF40X80S-08A Is Used
Decentralized Assembly Stations
Eliminates the need for a remote valve island on large machines, driving the 628 N clamping action directly from a single AC220V coil signal.
Space-Constrained Machinery
The integrated 4M210-08 valve and manifold block save valuable panel space and reduce plumbing complexity in tight automated cells.
Retrofit Sorting Systems
Ideal for upgrading existing conveyors where routing new air tubing back to a central manifold is impractical or too costly.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF40X80S-08A the Right Choice?
Choose this 40 mm bore when you need 628 N push force at 0.5 MPa, stepping up from the 32 mm bore (402 N push) for higher workloads, or down from the 50 mm bore (982 N push) to save space. The self-valved SAIF design is ideal for space-tight machines and decentralized stations where running separate valve tubing is costly. The AC220V terminal coil draws 3.5 VA, features IP65 protection, and responds in 0.05 seconds or less. For replacements, match the 40 mm bore, 80 mm stroke, 1/4 inch valve port, AC220V voltage, terminal entry, PT thread, and the -S magnet.
Remember that the built-in 5/2 valve routes air and does not mechanically hold a load without live pressure. The variable air cushions only decelerate the piston near the stroke ends. For true load-holding requirements, consider an AirTAC SAIL lock cylinder instead.
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 SAIF40X80S-08A FAQ
At 0.5 MPa, this 40 mm bore cylinder generates 628 N of push force and 528 N of pull force. The built-in 4M210-08 5/2 valve has a 16.0 mm2 effective area (Cv 0.89) and supports a maximum frequency of 5 cycles per second.
No, the integrated 4M210 valve switches the cylinder directly from one AC220V terminal coil signal. Factory-set to retract-when-energized, the valve can be repositioned on the manifold to extend-when-energized if your application requires the opposite action.
