Airtac SAIF Series Standard Cylinder with Valve SAIF50X125S-06A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF50X125S-06A 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 SAIF50X125S-06A
The AirTAC SAIF50X125S-06A is a double-acting ISO 15552 profile cylinder featuring an integrated 4M210-06 5/2 solenoid valve. Driven by an AC220V terminal connection coil drawing 3.5 VA, it achieves a 0.05 s response time. The built-in valve provides an effective flow area of 14.0 mm2 (Cv 0.78). Because the valve manifold mounts directly using O8 x O5 PU tubing, you save panel space by eliminating remote plumbing.
This self-switching unit delivers 982 N of push force at 0.5 MPa. While the cylinder body rates to 1.0 MPa, the integrated valve operates at 0.15-0.8 MPa, establishing the practical working range for the assembly. Factory-set to retract when energised, the valve can be repositioned to extend on signal. The -S magnet enables position sensing with CMSE reed or DMSE electronic switches.

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)

|---|---|---|
| 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 SAIF50X125S-06A Is Used
Decentralized Stations
Eliminates remote valve plumbing on large machines by integrating the 5/2 valve directly on the cylinder body.
Compact Assembly Lines
Saves valuable panel space while delivering 982 N of push force for mid-duty positioning tasks.
Wiring Retrofits
Ideal for upgrades where running new pneumatic tubing is difficult, needing only a single AC220V electrical signal.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF50X125S-06A the Right Choice?
Choose this 50 mm bore when you need 982 N push thrust at 0.5 MPa; stepping down to a 40 mm bore yields 628 N, while a 63 mm bore provides 1559 N. The SAIF50X125S-06A excels in decentralized installations where running air tubing to a remote valve is costly, as one electrical signal drives the entire actuator. The 1/4" cylinder port and 1/8" valve port provide distinct airflow paths. Remember the 5/2 valve routes air but does not lock the load; for position holding, consider an AirTAC SAIL lock cylinder. Replacement requires matching the 125 mm stroke, 06 valve port, AC220V terminal coil, PT threads, and -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 SAIF50X125S-06A FAQ
At 0.5 MPa it provides 982 N push and 825 N pull force. The built-in 4M210-06 valve has a 14.0 mm2 orifice (Cv 0.78) and a max frequency of 5 cycles/sec.
The 5/2 valve is internal piloted and holds its last position via pilot pressure, not a spring. Factory set to retract when energised, it can be repositioned to extend when energised. It operates on 0.15-0.8 MPa.
