Airtac SAIF Series Standard Cylinder with Valve SAIF40X100S-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF40X100S-08A is a genuine double-acting ISO 15552 cylinder with a Ø40mm bore, 100mm 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 SAIF40X100S-08A
The AirTAC SAIF40X100S-08A is a double-acting ISO 15552 profile cylinder featuring a built-in 4M210-08 5/2 solenoid valve. This integrated assembly provides a Cv of 0.89 and eliminates the need for remote plumbing. Driven by an AC220V terminal coil, it operates on 3.5 VA with an IP65 rating and a rapid 0.05s activation time. The included magnet (-S) supports CMSE reed and DMSE electronic sensors for position detection.
While the base cylinder rates to 1.0 MPa, the practical working range for this valved unit is 0.15-0.8 MPa. It generates 628N of push force at 0.5 MPa. By default, the piston rod retracts when the coil is energised, but you can reconfigure it to extend-when-energised simply by repositioning the valve. The manifold connects to the cylinder via O8xO5 PU tubing, and the valve port (1/4") is distinct from the cylinder port (1/4").

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)

|---|---|---|
| 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 SAIF40X100S-08A Is Used
Decentralized Automation Cells
Ideal for large machines where running individual valve tubing back to a central manifold is costly. The AC220V terminal coil needs only a simple electrical signal to drive the 628N motion locally.
Compact Assembly Stations
The built-in 4M210-08 valve shrinks the pneumatic footprint. With a 100mm stroke and CMSE/DMSE sensor compatibility, it handles precise part placement in tight work cells.
Machine Retrofitting
Upgrade older machines by replacing standalone cylinders. The integrated valve and O8xO5 PU manifold tubing simplify wiring and plumbing without major redesigns.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF40X100S-08A the Right Choice?
Choose this 40mm bore model when your application requires 628N push force at 0.5 MPa. If you need less force and tighter spacing, the 32mm bore offers 402N; for heavier loads up to 982N, step up to the 50mm bore. The SAIF40X100S-08A excels over a separate cylinder and remote valve by drastically reducing panel space and tubing runs, making it perfect for decentralized stations.
Remember that the 5/2 valve routes air but does not lock the load; if you need true position holding, consider the SAIL lock cylinder. This specific configuration uses a PT tapered port thread, an AC220V terminal connection, and a 100mm stroke. Ensure your replacement matches the bore, stroke, valve port, coil voltage, and -S magnet requirement.
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 SAIF40X100S-08A FAQ
The 40mm bore generates 628N of push force and 528N of pull force at 0.5 MPa. The built-in 4M210-08 5/2 valve provides an effective area of 16.0 mm2 (Cv 0.89) and supports a max frequency of 5 cycles per second.
By factory default, energising the AC220V terminal coil retracts the piston rod. This behavior can be reconfigured to extend-when-energised by physically repositioning the 5/2 valve on the manifold block.
