Airtac SAIF Series Standard Cylinder with Valve SAIF50X50S-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF50X50S-08A is a genuine double-acting ISO 15552 cylinder with a Ø50mm bore, 50mm stroke and a built-in 4M210-08 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-08A
The AirTAC SAIF50X50S-08A is a double-acting ISO 15552 profile cylinder featuring a built-in 4M210-08 5/2 solenoid valve. Driven by an AC220V terminal entry coil drawing 3.5 VA, it delivers a Cv of 0.89 and generates 982 N of push force at 0.5 MPa. The integrated manifold connects via an O8 x O5 PU tube to the cylinder port, meaning the 1/4" valve port handles the supply while the cylinder itself uses a 1/4" PT thread. Because the valve limits the system, the practical operating pressure is 0.15-0.8 MPa despite the cylinder body rating.
This unit includes a magnet (-S) for CMSE reed and DMSE electronic sensors. Factory set to retract the rod when energized, the valve can be repositioned to extend on signal. By switching itself from one coil signal, it eliminates remote plumbing and saves panel space for decentralized 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 SAIF50X50S-08A Is Used
Decentralized Automation Cells
Eliminates the need for a remote valve island on large machines by switching locally via the AC220V terminal coil, drastically reducing tubing runs.
Compact Assembly Stations
Delivers 982 N of thrust in a tight footprint, using the built-in 4M210 valve to cycle at up to 5 cycles per second without external manifolds.
Retrofit and Upgrades
Ideal for upgrading existing ISO 15552 fixtures where adding pneumatic plumbing is difficult; simply supply air to the 1/4" valve port and wire the coil.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF50X50S-08A the Right Choice?
Choose this 50mm bore when you need 982 N push force at 0.5 MPa; step down to a 40mm bore for 628 N, or up to a 63mm bore for 1559 N if your payload requires more thrust. The self-valved SAIF design is ideal for space-tight machines where running separate valve tubing is costly, as the AC220V terminal coil wires directly to the station. For position feedback, pair the internal magnet with AirTAC CMSE or DMSE switches.
Remember that the 5/2 valve routes air and is not a lock; if your machine needs to hold a load without live pressure, use an SAIL lock cylinder instead. To replace this unit, match the 50mm bore, 50mm stroke, PT 1/4" valve port, AC220V voltage, terminal entry, 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-08A FAQ
At 0.5 MPa, the 50mm bore generates 982 N of push force and 825 N of pull force. The integrated 4M210-08 5/2 valve has an effective area of 16.0 mm2 (Cv 0.89) and supports a maximum frequency of 5 cycles per second.
No separate remote valve is needed. The unit operates from a single AC220V coil signal. By factory default, energizing the coil retracts the piston rod, but you can reposition the valve to make it extend-when-energised.
