Airtac SAIF Series Standard Cylinder with Valve SAIF40X150S-06B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF40X150S-06B is a genuine double-acting ISO 15552 cylinder with a Ø40mm bore, 150mm 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 SAIF40X150S-06B
The AirTAC SAIF40X150S-06B is a double-acting ISO 15552 profile cylinder with a built-in 4M210-06 5/2 solenoid valve, providing a Cv of 0.78. Driven by a DC24V terminal coil drawing 3.0 W, it integrates position sensing via an -S magnet compatible with CMSE reed and DMSE electronic sensors. While the cylinder body rates to 1.0 MPa, the practical operating range for this valved assembly is 0.15-0.8 MPa.
It delivers 628N of push force at 0.5 MPa and operates at 30-800 mm/s. The manifold connects the valve to the cylinder using O8xO5 PU tubing. By default, the piston rod retracts when the coil is energised, but you can reconfigure it to extend on signal by repositioning the valve, eliminating the need for a remote valve bank.

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 SAIF40X150S-06B Is Used
Decentralized Assembly Stations
Eliminates remote valve banks and complex plumbing, allowing independent cylinder control directly at the workstation.
Space-Tight Material Handling
Fits within ISO 15552 envelope limits while integrating the 4M210 valve, saving valuable panel and machine footprint.
Machine Retrofitting
Simplifies upgrades by using a single DC24V signal to drive the cylinder, bypassing the need to install new centralized valve islands.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF40X150S-06B the Right Choice?
Choose this 40mm bore when you need 628N push force at 0.5 MPa; step down to a 32mm bore for 402N, or up to a 50mm bore for 982N. A self-valved SAIF is ideal for decentralized stations where running separate valve tubing wastes space and wiring. This unit uses a DC24V terminal connection with PT threaded ports. The 1/8 cylinder port and 06 valve port are distinct. For load-holding, note the 5/2 valve routes air but does not lock; use a SAIL lock cylinder instead. At 150mm stroke, ensure proper guide support to prevent side-load wear.
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 SAIF40X150S-06B FAQ
The 40mm bore generates 628N push force at 0.5 MPa and 879N at 0.7 MPa. The built-in 4M210-06 valve provides an effective area of 14.0 mm2 (Cv 0.78).
Yes. The factory setting retracts the rod when the DC24V coil is energised, but you can reposition the 5/2 valve to extend-when-energised. This self-switching design requires no separate remote valve.
