Airtac SAIF Series Standard Cylinder with Valve SAIF50X350S-06B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF50X350S-06B is a genuine double-acting ISO 15552 cylinder with a Ø50mm bore, 350mm 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 SAIF50X350S-06B
The AirTAC SAIF50X350S-06A is a double-acting ISO 15552 profile cylinder fitted with a built-in 4M210-06 5/2 solenoid valve. This specific configuration uses a DC24V terminal electrical entry and includes a magnet for position sensing with AirTAC CMSE reed and DMSE electronic switches. The integrated valve provides a 14.0 mm2 effective area (Cv 0.78) and operates at 5 cycles per second. Because the cylinder body rates to 1.0 MPa but the 5/2 valve limits pressure, the practical working range for the assembled unit is 0.15-0.8 MPa.
By generating 982 N of push force at 0.5 MPa, this 50 mm bore unit handles substantial workloads while switching itself from a single coil signal. The factory setting retracts the piston rod when the coil is energised, but you can reposition the valve to extend-when-energised if your logic requires it. The manifold connects to the cylinder via O8 x O5 PU tubing, and the valve port (1/8 inch) differs from the cylinder port, eliminating the need for separate remote valves and extensive plumbing.

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 (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa | 1374 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 SAIF50X350S-06B Is Used
Decentralized Automation Stations
Ideal for large machines with multiple nodes, allowing each station to control its own actuation via a single DC24V signal without running air lines back to a central manifold.
Extended Stroke Assembly
The 350 mm stroke suits parts transfer and long-travel clamping tasks, while the built-in valve keeps the cycle time fast with a 5 Hz max frequency.
Space-Constrained Retrofits
Perfect for upgrading existing ISO 15552 fixtures where adding external valve plumbing is too costly or space-prohibitive, offering integrated CMSE/DMSE sensor tracking.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF50X350S-06B the Right Choice?
Select this self-valved SAIF model when you need decentralized control across a large machine, as it saves panel space and reduces tubing runs compared to a separate cylinder and remote valve. If you need less force, stepping down to a 40 mm bore yields 628 N push at 0.5 MPa; if your application requires more thrust, stepping up to a 63 mm bore provides 1559 N. Keep in mind the built-in 5/2 valve routes air but does not lock the load mechanically—use SAIL or BSAI cylinders if you need true position holding. This 350 mm stroke exceeds 300 mm, so ensure you provide adequate guide rails to prevent excessive side-loading and premature seal wear. To replace this unit, match the 50 mm bore, 350 mm stroke, 1/8 inch valve port, DC24V terminal coil, PT thread, and the -S magnet option.
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 SAIF50X350S-06B FAQ
The 50 mm bore generates 982 N push and 825 N pull force at 0.5 MPa. The built-in 4M210-06 valve has a 14.0 mm2 effective area (Cv 0.78) and supports up to 5 cycles per second.
It uses a 5/2 solenoid valve that holds its position via internal pilot pressure, not a spring. The factory default retracts the rod when the DC24V coil energizes, but you can reposition the valve to extend-when-energised. No separate remote valve is needed.
