Airtac SAIF Series Standard Cylinder with Valve SAIF50X50S-06B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF50X50S-06B is a genuine double-acting ISO 15552 cylinder with a Ø50mm bore, 50mm 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 SAIF50X50S-06B
The AirTAC SAIF50X50S-06B is a double-acting ISO 15552 profile cylinder with a built-in 4M210-06 5/2 solenoid valve, offering an effective flow of Cv 0.78. Driven by a DC24V terminal coil consuming 3.0 W, it switches itself from one signal without needing a remote valve. The cylinder body rates to 1.0 MPa, but because the internal pilot valve operates at 0.15-0.8 MPa, the practical working range for this assembled unit is 0.15-0.8 MPa. In the 50 mm bore class, it delivers 982 N of push force at 0.5 MPa and reaches speeds of 30-800 mm/s.
This assembly uses a carbon steel piston rod and includes a magnet for CMSE reed and DMSE electronic sensors. The manifold connects to the cylinder via O8 x O5 PU tubing, and the valve port is 1/8 inch (PT), which is distinct from the 1/4 inch cylinder port. Factory-set to retract the rod when the coil is energised, the valve can be repositioned to extend-when-energised if your cycle logic requires it.

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 SAIF50X50S-06B Is Used
Decentralized Automation Cells
Eliminates remote valve banks on large machines by self-switching via the built-in 4M210 valve, reducing tubing complexity.
Space-Constrained Mechanisms
Fits into tight machine frames where routing separate valve tubing is difficult, providing 982 N push force from a compact profile.
Retrofit Positioning Stations
Upgrades existing lines easily by using the integrated DC24V terminal coil and manifold block, avoiding new pneumatic plumbing.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF50X50S-06B the Right Choice?
Choose this 50 mm bore when you need higher thrust than a 40 mm cylinder (which provides 628 N push at 0.5 MPa), but want a more compact footprint than the 63 mm bore (1559 N). A self-valved SAIF beats a separate cylinder plus remote valve in decentralized stations by cutting tubing runs, saving panel space, and wiring to a single DC24V terminal connection. If your machine needs to hold a load unpowered, note the 5/2 valve routes air but does not lock; consider SAIL or BSAI for clamp-lock functions. To replace this unit, match the 50 mm bore, 50 mm stroke, 1/8 inch valve port, DC24V voltage, terminal entry, PT threads, and the -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 SAIF50X50S-06B FAQ
The 50 mm bore generates 982 N push and 825 N pull force at 0.5 MPa. The built-in 4M210-06 5/2 valve has a 14.0 mm2 orifice with a Cv of 0.78.
No separate remote valve is needed; the DC24V coil drives the cylinder directly. It is factory set to retract when energised, but you can reposition the valve to extend-when-energised.
