Airtac SAIF Series Standard Cylinder with Valve SAIF40X300-06A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF40X300-06A is a genuine double-acting ISO 15552 cylinder with a Ø40mm bore, 300mm 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 SAIF40X300-06A
The AirTAC SAIF40X300-06A is a double-acting ISO 15552 profile cylinder featuring an integrated 4M210-06 5/2 solenoid valve. Driven by an AC220V terminal coil drawing 3.5 VA, it delivers a 0.5 MPa push force of 628N. The built-in valve has a 14.0 mm2 orifice (Cv 0.78) and cycles up to 5 times per second. Because the valve manifold mounts directly to the profile barrel using O8xO5 PU tubing, you eliminate remote plumbing.
While the cylinder body rates to 1.0 MPa, the valved assembly operates at 0.15-0.8 MPa. The factory setting retracts the piston rod when the coil energises, but you can reposition the valve to extend on signal. This self-switching design excels in decentralized machine stations by cutting panel space and wiring.

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)
| Pressure | Push force | Pull force |
|---|---|---|
| 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 SAIF40X300-06A Is Used
Decentralized Assembly Stations
Eliminates the need for a remote valve island on large machines, driving the 628N rod directly from a single AC220V signal.
Space-Tight Machinery
The integrated 4M210-06 valve manifold saves valuable panel space and reduces complex tubing runs in compact enclosures.
Retrofit Automation Upgrades
Ideal for upgrading existing lines where routing new pneumatic tubing back to a central controller is impractical or expensive.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF40X300-06A the Right Choice?
Choose this 40mm bore if you need more thrust than the 32mm class (402N at 0.5 MPa) but lack the physical envelope for a 50mm unit. The integrated 4M210-06 valve with a PT1/8 port handles flow efficiently, making it ideal for space-tight machines where running separate valve tubing is costly. For this 300mm stroke, ensure adequate side-load guidance to prevent premature seal wear.
Remember that the 5/2 valve routes air and is not a mechanical lock; the air cushion only decelerates near stroke end. If your application requires true load-holding without live pressure, consider the SAIL lock variant. To replace this unit, match the 40mm bore, 300mm stroke, 1/8 cylinder port, 06 valve port, AC220V terminal coil, 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 SAIF40X300-06A FAQ
At 0.5 MPa operating pressure, this 40mm bore cylinder provides a push force of 628N and a pull force of 528N. The practical operating pressure for the assembled unit is 0.15-0.8 MPa.
No, the integrated 4M210-06 is an internally piloted 5/2 solenoid valve. It switches the cylinder directly from the AC220V terminal coil signal, with a factory default that retracts the rod when energised.
