Airtac SAIF Series Standard Cylinder with Valve SAIF50X350-06B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF50X350-06B 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 SAIF50X350-06B
The AirTAC SAIF50X350-06B is a double-acting profile cylinder dimensionally interchangeable per ISO 15552, featuring a built-in 4M210-06 5/2 solenoid valve. This integrated valve delivers a Cv of 0.78 (14.0 mm2 effective area) and operates at a maximum frequency of 5 cycles per second. Bundled with a DC24V terminal entry coil consuming 3.0 W, it provides IP65 protection and a 0.05 s activation time. Because the cylinder body rates to 1.0 MPa but the internal pilot valve runs 0.15-0.8 MPa, the practical working pressure for this assembled unit is 0.15-0.8 MPa.
By controlling itself from a single coil signal, this model eliminates remote plumbing and saves panel space, making it ideal for decentralized stations across large machines. The manifold connects to the cylinder via PU tubing (O8 x O5). It generates 982 N of push force and 825 N of pull force at 0.5 MPa. Factory set to retract the rod when the coil is energised, the valve can be repositioned to extend-when-energised if your sequence requires it.

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)

|---|---|---|
| 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 SAIF50X350-06B Is Used
Decentralized Automation Cells
Perfect for large machines with multiple stations, mounting the valve directly on the cylinder eliminates long pneumatic runs from a central manifold.
Space-Constrained Machinery
The integrated 4M210 valve manifold saves valuable panel and footprint space in tight assembly fixtures.
Retrofit & Upgrades
Ideal for upgrading existing lines where running new valve tubing is costly, simply provide a DC24V signal to drive the 350mm stroke.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF50X350-06B the Right Choice?
Choose this 50mm bore when you need higher thrust than a 40mm bore (which provides 628 N push at 0.5 MPa) but want a more compact footprint than a 63mm bore (1559 N push). The self-valved SAIF50X350-06B outperforms a separate cylinder and remote valve setup by cutting tubing runs and simplifying wiring. Your exact replacement must match the 350mm stroke, 1/8" cylinder port, 06 (1/8") valve port, DC24V terminal coil, PT thread, and no magnet. Note that the 5/2 valve routes air but does not hold the load without live pressure; for position holding consider the SAIL lock series.
Since the 350mm stroke exceeds 300mm, ensure adequate side-load support and use a guide rail to prevent rod binding. The unit operates at speeds of 30-800 mm/s and uses a carbon steel piston rod with standard seals.
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 SAIF50X350-06B FAQ
At 0.5 MPa, this 50mm bore cylinder provides 982 N of push force and 825 N of pull force. The maximum thrust is 200 kgf at 1.0 MPa, but the practical working pressure is limited to 0.15-0.8 MPa by the built-in valve.
No, the integrated 4M210-06 5/2 solenoid valve handles directional control. Driven by a DC24V terminal coil (3.0 W, IP65), it switches the cylinder directly. The factory setting retracts the rod when energised, but the valve can be repositioned to extend-when-energised.
