Airtac SAIF Series Standard Cylinder with Valve SAIF40X50S-06B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF40X50S-06B is a genuine double-acting ISO 15552 cylinder with a Ø40mm 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 SAIF40X50S-06B
The AirTAC SAIF40X50S-06B is a double-acting ISO 15552 profile cylinder with an integrated 4M210-06 5/2 solenoid valve, yielding a 14.0 mm2 effective area (Cv 0.78). Driven by a DC24V terminal coil drawing 3.0 W, it switches itself in 0.05 s without remote plumbing. The cylinder body rates to 1.0 MPa, but the internal pilot valve operates at 0.15-0.8 MPa, setting the practical working range for the assembled unit. A carbon steel rod and PT1/8 cylinder port are standard.
It delivers 628 N push and 528 N pull at 0.5 MPa. The manifold uses O8 x O5 PU tubing, and the valve port code 06 (1/8") differs from the cylinder port. Factory-set to retract when energised, the valve can be repositioned to extend on signal. The -S magnet supports CMSE reed and DMSE electronic sensors for position feedback.

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 (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 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 SAIF40X50S-06B Is Used
Decentralized Assembly Lines
Eliminates remote valve islands by switching locally from a single DC24V signal, reducing tubing across large factory layouts.
Compact Clamping Stations
Provides 628 N push force at 0.5 MPa in tight spaces where running separate valve plumbing is mechanically impractical.
Sensor-Ready Automation
The -S magnet pairs with CMSE and DMSE switches to confirm clamping or release positions in automated processing.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF40X50S-06B the Right Choice?
Choose this 40mm bore when a 32mm bore (402 N push at 0.5 MPa) is insufficient, but a 50mm bore (982 N) is oversized. The self-valved SAIF excels in decentralized stations by eliminating separate valve islands and long tubing runs, saving panel space. A DC24V terminal entry suits standard low-voltage control systems. If the load must hold position without live pressure, select a SAIL lock cylinder instead, as the 5/2 valve only routes air and does not brake. For replacement, match the 50mm stroke, 4M210-06 valve, DC24V terminal coil, 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 SAIF40X50S-06B FAQ
At 0.5 MPa, this 40mm bore cylinder generates 628 N of push force and 528 N of pull force. The practical operating pressure is 0.15-0.8 MPa.
The integrated 5/2 valve is powered by a DC24V terminal coil (3.0 W). Factory-set to retract the rod when energised, it can be repositioned to extend on signal, eliminating the need for a separate remote valve.
