Airtac SAIF Series Standard Cylinder with Valve SAIF50X150-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF50X150-08A is a genuine double-acting ISO 15552 cylinder with a Ø50mm bore, 150mm 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 SAIF50X150-08A
The AirTAC SAIF50X150-08A is a double-acting ISO 15552 profile cylinder featuring an integrated 4M210-08 5/2 solenoid valve. The built-in valve provides an effective flow area of 16.0 mm2 (Cv 0.89) and operates at 5 cycles per second. It features a carbon steel piston rod, a PT1/4 cylinder port, and connects the manifold to the cylinder using O8 x O5 PU tubing. Because the cylinder body rates to 1.0 MPa but the internal valve limits the system, the practical operating pressure range for this assembled unit is 0.15-0.8 MPa.
Equipped with an AC220V terminal-style coil drawing 3.5 VA, the unit achieves IP65 protection and responds in 0.05 seconds or less. Delivering 982 N of push thrust and 825 N of pull thrust at 0.5 MPa, it switches itself from a single electrical signal. The factory default setting retracts the rod when the coil is energised, though you can reconfigure it to extend-when-energised simply by repositioning the valve. This integrated design eliminates the need for a separate remote valve, reducing tubing and panel space 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 SAIF50X150-08A Is Used
Decentralized Automation Cells
Eliminates the need for remote valve islands on large machines by switching locally via the integrated 4M210 valve, drastically cutting pneumatic tubing runs.
Compact Assembly Stations
Saves valuable panel and floor space by mounting the 5/2 solenoid directly on the ISO 15552 profile cylinder, ideal for tight robotic workcells.
Wiring Simplification Retrofits
Upgrades older machines easily by requiring only a single AC220V electrical connection to control the cylinder, bypassing complex air manifold rewiring.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF50X150-08A the Right Choice?
Choose this 50 mm bore when you need around 982 N of push force at 0.5 MPa; step down to a 40 mm bore (628 N push) for lighter loads, or up to a 63 mm bore (1559 N push) if you need significantly more thrust. The self-valved SAIF architecture is optimal for decentralized installations where running air tubing back to a central manifold is costly or space-prohibitive. This specific configuration uses an AC220V terminal entry coil and a PT1/4 valve port.
When specifying a replacement, match the 50 mm bore, 150 mm stroke, 4M210-08 valve, AC220V voltage, terminal entry, and PT thread. Note that the 5/2 valve routes air and the end cushions only decelerate the piston near stroke end; neither function locks the load. If your application requires true mechanical load-holding, consider the SAIL lock variant instead. The standard carbon steel rod is suitable for general industrial environments.
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 SAIF50X150-08A FAQ
At 0.5 MPa, this 50 mm bore cylinder generates 982 N of push force and 825 N of pull force. The integrated 4M210-08 5/2 valve provides an effective flow area of 16.0 mm2 (Cv 0.89) with a maximum operating frequency of 5 cycles per second.
No, the SAIF50X150-08A has a built-in 4M210-08 valve actuated by an AC220V terminal coil. By default, the factory setting retracts the rod when the coil is energised, but this can be reconfigured to extend-when-energised by repositioning the valve.
