Airtac SAIF Series Standard Cylinder with Valve SAIF50X125-06A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF50X125-06A 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 SAIF50X125-06A
The AirTAC SAIF50X125-06A is a double-acting ISO 15552 profile cylinder featuring a built-in 4M210-06 5/2 solenoid valve. Driven by an AC220V terminal coil drawing 3.5 VA, it achieves a 0.05 s response time. The integrated valve provides a 14.0 mm2 effective area (Cv 0.78) and operates at 0.15-0.8 MPa, which sets the practical working range for this assembled unit since the valve limits the 1.0 MPa cylinder rating. With a 50 mm bore, it generates 982 N of push force at 0.5 MPa.
By switching itself from a single coil signal, this unit eliminates remote valves and excess tubing, making it perfect for decentralized stations across large machines. The manifold connects to the cylinder via O8 x O5 PU tubing, and the factory setting retracts the rod when the coil is energised. You can reposition the valve to extend-when-energised if your sequence requires it. The standard carbon steel rod and PT tapered threads ensure robust pneumatic sealing.

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 SAIF50X125-06A Is Used
Decentralized Machine Stations
Eliminates the need for a central valve manifold on large equipment by switching locally via the AC220V terminal coil, drastically reducing tubing runs.
Compact Assembly Automation
Fits into tight cell layouts where running separate valve tubing is costly, delivering 982 N of push force with a built-in 4M210-06 valve.
Retrofit & Upgrades
Drops into existing ISO 15552 dimensionally interchangeable footprints to upgrade a standard actuator into a self-switching unit without external plumbing.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF50X125-06A the Right Choice?
Choose this 50 mm bore when you need around 982 N of thrust 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 substantially more force. A self-valved SAIF beats a separate cylinder and remote valve in space-tight machines by cutting panel space and wiring. The 4M210-06 valve features a 1/8" port, while the cylinder port is 1/4". Remember the 5/2 valve routes air and is not a lock; the air cushion only decelerates near stroke end. For load-holding, select a SAIL lock cylinder. To replace this unit, match the 50 mm bore, 125 mm stroke, 06 valve port, AC220V terminal coil, PT threads, and no 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 SAIF50X125-06A FAQ
At 0.5 MPa, this 50 mm bore cylinder generates 982 N of push force and 825 N of pull force. The integrated 4M210-06 5/2 valve has an effective area of 14.0 mm2 (Cv 0.78) and a maximum frequency of 5 cycles per second.
No, the SAIF50X125-06A has a 4M210-06 valve built directly onto the manifold. It operates on AC220V with a terminal entry. By default, the rod retracts when the coil is energised, but you can reposition the valve to extend-when-energised.
