Airtac SAIF Series Standard Cylinder with Valve SAIF50X350S-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF50X350S-08B is a genuine double-acting ISO 15552 cylinder with a Ø50mm bore, 350mm stroke and a built-in 4M210-08 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-08B
The AirTAC SAIF50X350S-08B is a double-acting ISO 15552 profile cylinder featuring an integrated 4M210-08 5/2 solenoid valve. Driven by a DC24V terminal coil drawing 3.0 W, it delivers a 0.89 Cv flow rate and generates 982N of push force at 0.5 MPa. The assembly operates within a 0.15-0.8 MPa pressure range because the built-in valve governs the 1.0 MPa cylinder rating. An included magnet enables position sensing with AirTAC CMSE reed or DMSE electronic switches.
By switching itself from a single coil signal, this unit eliminates remote plumbing and saves panel space, making it perfect for decentralized stations. The manifold connects to the cylinder via O8xO5 PU tubing, while the factory default setting retracts the rod when energized. You can reposition the valve to extend-when-energized 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)
| 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-08B Is Used
Decentralized Stations
Ideal for large machines with multiple stations, eliminating long tubing runs by mounting the valve directly on the cylinder.
Space-Tight Machinery
Perfect for compact assemblies where external valve banks cannot fit, driving 982N of force from a single DC24V signal.
Retrofit Installations
Simplifies upgrades on existing lines by reducing wiring complexity and panel space requirements through integrated control.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF50X350S-08B the Right Choice?
Choose this 50mm bore when you need 982N push force at 0.5 MPa; step down to a 40mm bore for 628N, or up to a 63mm bore for 1559N. The self-valved SAIF architecture is ideal for space-tight machines where running separate valve tubing is costly. For this 350mm stroke, ensure adequate side-load guidance to prevent rod binding. The 5/2 valve routes air but does not lock the load—select a SAIL lock cylinder if static holding is required. Replacement requires matching the 50mm bore, 350mm stroke, 1/4" valve port, DC24V terminal coil, 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 SAIF50X350S-08B FAQ
The built-in 4M210-08 valve provides a 16.0 mm2 effective area (Cv 0.89). The 50mm bore cylinder generates 982N push force and 825N pull force at 0.5 MPa.
No, the integrated 5/2 valve switches the cylinder directly from the DC24V terminal coil signal. The factory setting retracts the rod when energized, but it can be reconfigured to extend-when-energized by repositioning the valve.
