Airtac SAIF Series Standard Cylinder with Valve SAIF40X500S-06A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF40X500S-06A is a genuine double-acting ISO 15552 cylinder with a Ø40mm bore, 500mm 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 SAIF40X500S-06A
The AirTAC SAIF40X500S-06A is a double-acting ISO 15552 profile cylinder featuring a built-in 4M210-06 5/2 solenoid valve. This integrated valve provides an effective flow of 14.0 mm2 (Cv 0.78) and operates at up to 5 cycles per second. Equipped with an AC220V terminal connection coil drawing 3.5 VA, it switches in 0.05 seconds. The cylinder features a 16mm carbon steel rod, PT1/4 cylinder ports, and an -S magnet for CMSE reed or DMSE electronic sensors.
While the cylinder body rates to 1.0 MPa, the integrated valve limits the practical working pressure to 0.15-0.8 MPa. The manifold connects the valve to the cylinder using O8xO5 PU tubing, meaning the valve port (1/8) differs from the cylinder port (1/4). By default, the factory setting retracts the piston rod when the coil is energised, though you can reposition the valve to extend on signal. This self-switching design eliminates remote plumbing, saving panel space for decentralized machine layouts.

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 SAIF40X500S-06A Is Used
Decentralized Assembly Lines
Reduces pneumatic plumbing across large machines by driving the 40mm bore directly from its built-in valve, eliminating long tubing runs to a central panel.
Space-Constrained Robotics
Fits tight envelopes where a separate 5/2 valve would exceed available space, providing 628N push force at 0.5 MPa without external manifold blocks.
Wiring-Retrofit Upgrades
Simplifies machine upgrades by replacing a standard cylinder and remote valve setup with a single AC220V terminal-driven unit, minimizing new air leaks.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF40X500S-06A the Right Choice?
Choose this 40mm bore when you need 628N push force (528N pull) at 0.5 MPa. If your application requires less force, the 32mm bore offers 402N push at 0.5 MPa; for heavier loads, stepping up to the 50mm bore provides 982N push at 0.5 MPa. The SAIF40X500S-06A is ideal when decentralized stations make running separate valve tubing costly, as one AC220V terminal signal controls the cylinder directly.
Because the stroke is 500mm, ensure adequate side-load support and use a guide to prevent rod bending. Remember that the 5/2 valve routes air but does not lock the load; if you need true position holding under pressure loss, consider the SAIL lock series. For replacements, verify the 40mm bore, 500mm stroke, 1/8 valve port, AC220V voltage, terminal entry, PT thread, and -S magnet.
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 SAIF40X500S-06A FAQ
At 0.5 MPa, this 40mm bore cylinder provides 628N of push force and 528N of pull force. If operated at 0.7 MPa, the push force increases to 879N.
No, the integrated 4M210-06 5/2 valve controls the cylinder directly from one AC220V coil signal. By factory default, it retracts the rod when energised, but you can reposition the valve to extend on signal.
