Airtac SAIF Series Standard Cylinder with Valve SAIF50X900-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF50X900-08A is a genuine double-acting ISO 15552 cylinder with a Ø50mm bore, 900mm 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 SAIF50X900-08A
The AirTAC SAIF50X900-08A is a double-acting ISO 15552 profile cylinder paired with a built-in 4M210-08 5/2 solenoid valve. This integrated manifold block uses an O8xO5 PU tube to connect the valve to the cylinder, eliminating the need for remote plumbing. The valve provides an effective flow area of 16.0 mm2 (Cv 0.89) and switches at a maximum frequency of 5 cycles per second. Equipped with an AC220V terminal entry coil, it consumes 3.5 VA and features IP65 protection with a 0.05s activation time. Because the valve operates at 0.15-0.8 MPa, this defines the practical working pressure range for the assembled unit, even though the cylinder body rates to 1.0 MPa.
Delivering 982N of push force at 0.5 MPa, this 50mm bore actuator is designed for decentralized installation across large machines. By routing air directly from the manifold, you save panel space and reduce tubing runs. The factory setting retracts the piston rod when the coil is energised, but you can reposition the valve to extend-when-energised if your sequence requires it. The carbon steel rod and extruded aluminum barrel provide durable, no-lubrication operation.

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 SAIF50X900-08A Is Used
Decentralized Stations
Ideal for large automated lines where running separate valve tubing is costly, allowing each station to switch itself via a single AC220V signal.
Long-Stroke Handling
The 900mm stroke suits extended material handling, with the 982N push force at 0.5 MPa handling moderate loads when guided properly.
Space-Tight Retrofits
Integrates the 4M210-08 valve directly on the profile barrel, saving valuable panel space and simplifying machine wiring upgrades.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF50X900-08A the Right Choice?
Choose this 50mm bore when 40mm (628N push at 0.5 MPa) is too weak or 63mm (1559N push at 0.5 MPa) is oversized. The SAIF50X900-08A is ideal when a self-valved actuator beats running separate valve tubing across a machine. For replacements, verify the 900mm stroke, 1/4" cylinder port, PT tapered threads, and the 4M210-08 valve with an AC220V terminal coil. Note that a 900mm stroke requires attention to side loads; always use appropriate guide rails to prevent rod damage.
Remember that the built-in 5/2 valve routes air but does not lock the load. If you need true position holding without live pressure, consider the AirTAC SAIL lock cylinder or BSAI clamp-lock series instead. The air cushion only decelerates the piston near the stroke ends.
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 SAIF50X900-08A FAQ
The 50mm bore cylinder provides 982N push and 825N pull force at 0.5 MPa. The built-in 4M210-08 5/2 valve has an effective area of 16.0 mm2 (Cv 0.89).
No, the integrated 4M210 valve controls the cylinder directly from one AC220V coil signal. The factory setting retracts the rod when energised, but you can reposition the valve to extend-when-energised.
