Airtac SAIF Series Standard Cylinder with Valve SAIF40X150S-06C
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF40X150S-06C 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-06C
The AirTAC SAIF40X150S-06C is a double-acting ISO 15552 profile cylinder with a built-in 4M210-06 5/2 solenoid valve, delivering a Cv of 0.78. It features a 40mm bore, 150mm stroke, and a carbon steel piston rod. Equipped with a -S magnet, it supports CMSE reed and DMSE electronic sensors for precise position detection. The integrated valve manifold uses an O8xO5 PU tube to connect the valve to the cylinder, meaning the 1/8 inch cylinder port and 1/8 inch valve port are distinct connections that must not be confused.
This model utilizes an AC110V terminal coil consuming 3.5 VA, protected to IP65 with a 0.05s activation time. While the cylinder body rates to 1.0 MPa, the practical SAIF operating range is 0.15-0.8 MPa due to the internal pilot valve limits. By default, the piston rod retracts when the coil is energised, but you can reconfigure it to extend-when-energised by repositioning the valve. It generates 628N of push force and 528N of pull force at 0.5 MPa.

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.

| 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-06C Is Used
Decentralized Machine Stations
Eliminates the need for a remote valve bank, allowing independent cylinder control directly at the station via a single AC110V signal.
Space-Constrained Automation
The integrated 4M210 valve and manifold block save valuable panel and footprint space in compact assembly machinery.
Retrofit and Upgrades
Ideal for upgrading existing ISO 15552 setups where running new pneumatic tubing from a central valve is costly or impractical.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF40X150S-06C the Right Choice?
Choose this 40mm bore when you need 628N push force at 0.5 MPa, stepping up from the 32mm bore (402N push) for heavier loads, or dropping down from the 50mm bore (982N push) to save space and air consumption. The self-valved SAIF design eliminates remote valves and long tubing runs, making it ideal for decentralized stations across large machines where panel space is tight. At 150mm stroke, ensure adequate guiding to prevent side-loading issues.
For replacements, match the 40mm bore, 150mm stroke, 06 (1/8 inch) valve port, AC110V terminal coil, PT thread, and -S magnet. Remember that the 5/2 valve routes air but does not lock the load; if you need true load holding, consider the SAIL lock cylinder or BSAI clamp-lock instead.
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-06C FAQ
At 0.5 MPa, this 40mm bore cylinder provides 628N of push force and 528N of pull force. The built-in 4M210-06 valve has an effective area of 14.0 mm2 (Cv 0.78) and operates at a maximum frequency of 5 cycles per second.
It uses an internal pilot 5/2 solenoid valve that holds its position via air pressure, not a spring. The factory default retracts the rod when the AC110V coil is energised, but you can reposition the valve to extend-when-energised. This integrated design means no separate remote valve is needed.
