Airtac SAIF Series Standard Cylinder with Valve SAIF40X80-06B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF40X80-06B is a genuine double-acting ISO 15552 cylinder with a Ø40mm bore, 80mm stroke and a built-in 4M210-06 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 SAIF40X80-06B
The AirTAC SAIF40X80-06B is a double-acting ISO 15552 profile cylinder featuring a built-in 4M210-06 5/2 solenoid valve. Driven by a DC24V terminal coil drawing 3.0 W with an IP65 rating and 0.05 s response time, it delivers 628 N of push force at 0.5 MPa. The integrated valve offers a 14.0 mm2 effective area (Cv 0.78) and eliminates the need for a separate remote valve, saving panel space and tubing for decentralized machine stations.
While the base cylinder rates to 1.0 MPa, the practical operating range for this assembled SAIF unit is 0.15-0.8 MPa because the internal piloted 5/2 valve operates within that band. The manifold connects to the cylinder via O8 x O5 PU tubing, routing air through the PT1/8 valve port to the cylinder's PT1/4 port. By factory default, the piston rod retracts when the coil is energised, but you can reconfigure it to extend-when-energised simply by repositioning the valve.

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 SAIF40X80-06B Is Used
Decentralized Automation Stations
Ideal for large machines with multiple nodes, eliminating long air lines by mounting the valve directly on the cylinder for localized control.
Compact Clamping Fixtures
Provides 628 N of push force at 0.5 MPa in tight machining cells where external valve banks would consume valuable fixture space.
Retrofit Space-Tight Machines
Simplifies upgrades on older equipment where routing new pneumatic tubing to a central manifold is impractical, requiring only a DC24V electrical signal.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF40X80-06B the Right Choice?
Choose this 40 mm bore when you need 628 N push force at 0.5 MPa and want to avoid the plumbing of a remote valve. If your application requires less force, stepping down to the 32 mm bore yields 402 N; if you need more clamping power, the 50 mm bore provides 982 N. The SAIF40X80-06B is ideal for space-tight machines where running separate valve tubing is costly, as one DC24V electrical signal directly controls the cylinder. It uses a PT tapered thread and lacks a piston magnet, so position sensing is not supported without modification.
Remember that the built-in 5/2 valve routes air but does not lock the load mechanically; if you need true load-holding, consider an AirTAC SAIL lock cylinder. When replacing this unit, match the 40 mm bore, 80 mm stroke, 06 (1/8) valve port, DC24V voltage, terminal entry, and PT thread type.
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 SAIF40X80-06B FAQ
At 0.5 MPa, the 40 mm bore generates 628 N of push force and 528 N of pull force. The built-in 4M210-06 5/2 valve has an effective area of 14.0 mm2 (Cv 0.78) and a maximum operating frequency of 5 cycles per second.
No, the SAIF40X80-06B has a built-in 4M210 valve actuated by a DC24V terminal coil. By factory default, the rod retracts when energised, but it can be reconfigured to extend-when-energised by repositioning the valve.
