Airtac SAIF Series Standard Cylinder with Valve SAIF50X175-06B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF50X175-06B is a genuine double-acting ISO 15552 cylinder with a Ø50mm bore, 175mm 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 SAIF50X175-06B
The AirTAC SAIF50X175-06B is a double-acting ISO 15552 profile cylinder featuring an integrated 4M210-06 5/2 solenoid valve. Driven by a DC24V terminal coil drawing 3.0 W, it delivers a 982N push force at 0.5 MPa. The carbon steel rod and extruded aluminum barrel ensure durable operation. Because the cylinder body rates to 1.0 MPa but the internal pilot valve is limited to 0.15-0.8 MPa, the practical working range for this assembled unit is 0.15-0.8 MPa.
By default, the factory setting retracts the piston rod when the coil is energised, though you can reconfigure it to extend-when-energised simply by repositioning the valve. The manifold connects to the cylinder using O8 x O5 PU tubing, meaning the 1/8 valve port and the 1/4 cylinder port serve distinct routing paths. Switching itself from one coil signal, it eliminates remote valves and reduces panel space, making it ideal 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 SAIF50X175-06B Is Used
Decentralized Stations
Perfect for large machines with decentralized stations, eliminating the need to run long valve tubing back to a central panel.
Compact Assembly Lines
Fits neatly into space-constrained assembly lines where mounting a separate remote valve and manifold is physically impossible.
Retrofit Automation
Ideal for retrofitting older pneumatic setups, dropping a self-switching cylinder directly into existing machine frames.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF50X175-06B the Right Choice?
Choose this 50mm bore when you need 982N of push thrust at 0.5 MPa; stepping down to a 40mm bore drops the push force to 628N, while upgrading to a 63mm bore yields 1559N. A self-valved SAIF beats a separate cylinder and remote valve in space-tight machines where running tubing is costly. This unit uses a DC24V terminal entry with PT tapered threads. If your machine loses power, the 5/2 valve routes air but does not lock the load—select a SAIL lock cylinder for true position holding. For stroke lengths at or above 300mm, always use a side-load guide to prevent rod damage, though this 175mm stroke is safely below that threshold. To match this exact unit for replacement, verify bore 50, stroke 175, 06 valve port, DC24V voltage, terminal entry, PT threads, and no sensor 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 SAIF50X175-06B FAQ
At 0.5 MPa, the 50mm bore provides 982N of push force and 825N of pull force. The built-in 4M210-06 valve has an effective area of 14.0 mm2 (Cv 0.78) and a maximum frequency of 5 cycles per second.
No, it has a built-in 4M210 5/2 valve actuated by a DC24V terminal coil. By factory default, the rod retracts when the coil is energised, but you can reposition the valve to extend-when-energised. It operates on 0.15-0.8 MPa.
