Airtac SAIF Series Standard Cylinder with Valve SAIF50X150S-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF50X150S-08A is a genuine double-acting ISO 15552 cylinder with a Ø50mm bore, 150mm 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 SAIF50X150S-08A
The AirTAC SAIF50X150S-08A is a double-acting ISO 15552 profile cylinder with a built-in 4M210-08 5/2 solenoid valve, delivering a Cv of 0.89 and a 16.0 mm2 effective area. Driven by an AC220V terminal entry coil drawing 3.5 VA, it switches itself via one electrical signal. The unit includes a magnet for CMSE reed and DMSE electronic sensors. While the bare cylinder rates to 1.0 MPa, the integrated valve operates at 0.15-0.8 MPa, establishing the practical working range for this assembly.
It delivers 982 N of push thrust and 825 N of pull at 0.5 MPa. The manifold connects to the cylinder using O8 x O5 PU tubing, meaning the 1/4" valve port differs from the cylinder's own port. Factory-set to retract the rod when energised, the valve can be repositioned to extend on signal. This eliminates remote plumbing and saves panel space, making it ideal 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)

|---|---|---|
| 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 SAIF50X150S-08A Is Used
Decentralized Machine Stations
Eliminates the need for a remote valve island on large machines, driving the cylinder directly via a single AC220V signal to reduce plumbing complexity.
Space-Tight Assembly Automation
The integrated 4M210-08 valve manifold saves valuable panel and footprint space while delivering 982 N of push force for compact clamping tasks.
Retrofit and Upgrades
Ideal for upgrading existing ISO 15552 setups where running new pneumatic tubing back to a central manifold is costly or impractical.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF50X150S-08A the Right Choice?
Choose this 50 mm bore when you need around 982 N push force at 0.5 MPa; step down to a 40 mm bore for 628 N, or up to a 63 mm bore for 1559 N. The self-valved SAIF architecture beats a separate cylinder and remote valve in space-tight machines by cutting tubing and wiring. The AC220V terminal coil offers IP65 protection and a 0.05 s response time. For position feedback, the -S magnet works with CMSE and DMSE switches.
Remember the 5/2 valve routes air but does not lock the load without live pressure; the variable air cushion only decelerates near stroke end. For true load-holding, consider a SAIL lock variant. To replace this unit, match the 50 mm bore, 150 mm stroke, PT1/4 valve port, AC220V voltage, terminal entry, PT thread, 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 SAIF50X150S-08A FAQ
At 0.5 MPa, this 50 mm bore cylinder provides 982 N of push force and 825 N of pull force. The built-in 4M210-08 5/2 valve has an effective area of 16.0 mm2 (Cv 0.89) and a maximum frequency of 5 cycles per second.
No, the integrated 4M210 valve switches the cylinder directly from the AC220V terminal coil signal. By default, the piston rod retracts when the coil is energised, but this can be reconfigured to extend-when-energised by repositioning the valve.
