Airtac SAIF Series Standard Cylinder with Valve SAIF40X700S-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF40X700S-08A is a genuine double-acting ISO 15552 cylinder with a Ø40mm bore, 700mm 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 SAIF40X700S-08A
The AirTAC SAIF40X700S-08A is a double-acting ISO 15552 profile cylinder featuring a built-in 4M210-08 5/2 solenoid valve. This integrated assembly delivers a Cv of 0.89 and generates 628N of push force at 0.5 MPa. It includes a magnet for position sensing using AirTAC CMSE reed or DMSE electronic switches. Because the cylinder body rates to 1.0 MPa but the internal pilot valve operates at 0.15-0.8 MPa, the practical working range for this valved unit is 0.15-0.8 MPa.
Equipped with an AC220V terminal entry coil drawing 3.5 VA, the unit activates in under 0.05 seconds. The factory default setting retracts the piston rod when the coil is energised, which can be reconfigured to extend-when-energised by repositioning the valve. The manifold uses O8xO5 PU tubing to link the valve block to the cylinder, meaning you only need one electrical signal to drive the actuator. This eliminates remote plumbing and is ideal for decentralized stations across large machines.

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 SAIF40X700S-08A Is Used
Decentralized Automation
Eliminates the need for long air tubing runs back to a central manifold, driving the 700mm stroke directly from a local AC220V signal.
Material Handling Gates
Provides 628N of push force to actuate routing gates and diverters on packaging lines where panel space for separate valves is limited.
Space-Constrained Machinery
The integrated 4M210-08 valve manifold saves valuable footprint inside compact machine frames while delivering a Cv of 0.89.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF40X700S-08A the Right Choice?
Choose this 40mm bore when you need 628N push force at 0.5 MPa and want to avoid the tubing and panel space of a separate remote valve. If your application requires less force, the 32mm bore provides 402N; stepping up to the 50mm bore yields 982N. This specific SKU specifies an AC220V terminal connection with PT threaded ports. For replacements, verify the 700mm stroke, 1/4" cylinder port, 4M210-08 valve port, and the -S magnet option.
With a 700mm stroke, adding an external guide is recommended to prevent excessive side-loading on the rod. Remember that the built-in 5/2 valve routes air but does not lock the load; if you need true mechanical load-holding, consider the SAIL lock variant. The carbon steel rod and adjustable air cushions handle speeds of 30-800 mm/s.
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 SAIF40X700S-08A FAQ
At 0.5 MPa, this 40mm bore cylinder provides 628N of push force and 528N of pull force. The built-in 4M210-08 valve has an effective area of 16.0 mm2 and a Cv of 0.89.
The 5/2 valve is internally piloted and holds its last position via pilot pressure, not a spring. By factory default, the rod retracts when the AC220V coil is energised, but this can be reconfigured to extend-when-energised by repositioning the valve.
