Airtac SAIF Series Standard Cylinder with Valve SAIF50X125-06B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF50X125-06B is a genuine double-acting ISO 15552 cylinder with a Ø50mm bore, 125mm 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 SAIF50X125-06B
The AirTAC SAIF50X125-06B is a double-acting ISO 15552 profile cylinder featuring an integrated 4M210-06 5/2 solenoid valve. Driven by a DC24V terminal coil consuming 3.0 W, it delivers 982N of push force at 0.5 MPa. The built-in valve provides a Cv of 0.78 and routes air directly via an O8xO5 PU tube, eliminating the need for remote plumbing. While the cylinder body rates to 1.0 MPa, the integrated valve limits the practical working pressure to 0.15-0.8 MPa.
By default, the factory valve setting retracts the piston rod when the coil is energised; mechanics can reposition the valve to extend-when-energised if the logic requires it. This self-contained assembly receives one electrical signal to switch itself, making it highly effective for decentralized stations across large machines where minimizing panel space and tubing runs is critical. The carbon steel piston rod operates at 30-800 mm/s.

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 SAIF50X125-06B Is Used
Decentralized Stations
Ideal for large machines needing isolated control, letting one DC24V signal drive the cylinder without running long pneumatic lines back to a central manifold.
Compact Assembly Lines
Fits space-constrained retrofits where adding a separate valve bank is impractical, providing 982N push force with a built-in 4M210 valve.
Automated Material Handling
Delivers reliable 125mm stroke actuation at up to 800 mm/s, simplifying wiring by integrating the switching valve directly onto the profile body.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF50X125-06B the Right Choice?
Select this 50mm bore when 982N push force at 0.5 MPa is sufficient; step down to a 40mm bore (628N push) for lighter loads, or up to 63mm (1559N push) if higher thrust is needed. The SAIF50X125-06B is ideal over a separate cylinder and remote valve when floor space is tight and running pneumatic lines is costly. It specifies a 1/8" cylinder port, a 1/8" valve port (code 06), DC24V voltage, terminal entry, and PT threads. Note that the 5/2 valve routes air but does not lock the load; for position holding, consider the SAIL lock series. Replacement requires matching bore, stroke, valve port, coil voltage, entry, and thread type.
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 SAIF50X125-06B FAQ
The 50mm bore generates 982N push and 825N pull force at 0.5 MPa. The built-in 4M210-06 valve has a 14.0 mm2 orifice with a Cv of 0.78.
Yes. The factory setting retracts the rod when the DC24V coil is energised, but you can reposition the 5/2 valve on its manifold to extend-when-energised.
