Airtac SAIF Series Standard Cylinder with Valve SAIF50X350S-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF50X350S-08A 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-08A
The AirTAC SAIF50X350S-08A is a double-acting ISO 15552 profile cylinder featuring an integrated 4M210-08 5/2 solenoid valve. The built-in valve provides a 16.0 mm2 effective area (Cv 0.89) and switches via an AC220V terminal entry coil consuming 3.5 VA. Because the valve mounts directly via a manifold block using O8xO5 PU tubing, it eliminates remote plumbing. The assembled unit operates safely within 0.15-0.8 MPa, as the valve pressure rating dictates the practical limit despite the cylinder body rating of 1.0 MPa.
This 50mm bore generates 982N of push force at 0.5 MPa and includes a magnet (-S) for CMSE reed or DMSE electronic sensors. From the factory, the piston rod retracts when the coil is energised, but you can reposition the valve to extend-when-energised. The carbon steel piston rod and PT1/4 cylinder port ensure robust, standardised pneumatic connections for decentralized machine stations.

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-08A Is Used
Decentralized Stations
Ideal for large machines with multiple stations, using the built-in valve to switch locally from one AC220V signal instead of running long pneumatic lines back to a central manifold.
Mid-Stroke Guiding
The 350mm stroke delivers 982N push force, requiring external guide rails to manage side loads during material handling or clamping tasks.
Space-Tight Retrofits
Perfect for machinery upgrades where mounting a separate valve and routing tubing is physically impossible or too costly, saving valuable envelope space.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF50X350S-08A the Right Choice?
Choose this self-valved SAIF unit when you need to reduce panel space and eliminate long tubing runs to a remote valve island. The 4M210-08 valve handles up to 5 cycles per second. If your application requires less force, stepping down to a 40mm bore yields 628N push at 0.5 MPa; stepping up to a 63mm bore provides 1559N. At a 350mm stroke, you must account for side loads and use a guide mechanism to prevent rod bending and premature seal wear.
This SKU uses an AC220V terminal entry coil with IP65 protection and a 0.05s response time. Remember that the 5/2 valve routes air and is not a lock; if you need fail-safe load holding, consider the SAIL series. For exact replacement, match the 50mm bore, 350mm stroke, PT1/4 cylinder port, 4M210-08 valve port, AC220V voltage, terminal entry, and the -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-08A FAQ
The 50mm bore generates 982N push and 825N pull force at 0.5 MPa. The integrated 4M210-08 5/2 valve provides an effective area of 16.0 mm2 (Cv 0.89) and supports a maximum frequency of 5 cycles per second.
No, the SAIF50X350S-08A has a built-in 4M210 valve driven by an AC220V terminal coil. By factory default, energising the coil retracts the rod, but you can reposition the valve to extend-when-energised. It operates within 0.15-0.8 MPa.
