Airtac SAIF Series Standard Cylinder with Valve SAIF40X50-06A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF40X50-06A is a genuine double-acting ISO 15552 cylinder with a Ø40mm bore, 50mm 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 SAIF40X50-06A
The AirTAC SAIF40X50-06A is a double-acting profile cylinder dimensionally interchangeable per ISO 15552, featuring a built-in 4M210-06 5/2 solenoid valve. This integrated manifold uses an O8xO5 PU tube to bridge the valve block to the PT1/8 cylinder port, eliminating the need for remote pneumatic plumbing. Driven by an AC220V terminal entry coil drawing 3.5 VA, it responds in 0.05s. The 4M210-06 valve provides a 14.0 mm2 effective area (Cv 0.78) and switches up to 5 cycles per second.
While the cylinder body rates to 1.0 MPa, the internal pilot valve operates from 0.15-0.8 MPa, setting the practical working range for the assembly. At 0.5 MPa it delivers 628N push and 528N pull force. The factory setting retracts the rod when the coil is energised, but you can reposition the valve to extend-when-energised. The 5/2 valve holds its position via pilot pressure, not a spring, though it will not hold a load safely without live air pressure.

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 SAIF40X50-06A Is Used
Decentralized Assembly Lines
Ideal for large machines with multiple stations, using the self-contained AC220V coil signal to actuate clamps without routing long pneumatic lines back to a central manifold.
Compact Part Ejection
Provides 628N of push force at 0.5 MPa in tight spaces, leveraging the built-in 4M210-06 valve to minimize the overall envelope and eliminate external valve plumbing.
Space-Constrained Retrofits
Perfect for upgrading existing ISO 15552 interchangeable setups where adding a separate remote valve would exceed available panel space or require complex tubing runs.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF40X50-06A the Right Choice?
Choose this 40mm bore when a 32mm bore (402N push at 0.5 MPa) lacks the necessary force, but a 50mm bore (982N push) would be excessive. The SAIF40X50-06A excels in decentralized stations across large machines where running separate valve tubing is costly, saving panel space and wiring. It uses a PT1/8 valve port and AC220V terminal electrical entry. For exact replacements, verify the 50mm stroke, 4M210-06 valve, AC220V voltage, terminal entry, PT thread, and the absence of a magnet (-S). Because the stroke is under 300mm, external side-load guides are less critical, but always verify load alignment.
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 SAIF40X50-06A FAQ
At 0.5 MPa, the cylinder generates 628N of push force and 528N of pull force. The built-in 4M210-06 valve has an effective area of 14.0 mm2 (Cv 0.78) and can operate up to 5 cycles per second.
The built-in 5/2 valve allows the cylinder to switch itself from a single AC220V terminal coil signal (3.5 VA, IP65), eliminating the need for a separate remote valve. By default, the rod retracts when the coil is energised, but this can be reconfigured to extend-when-energised by repositioning the valve.
