Airtac SAIF Series Standard Cylinder with Valve SAIF40X800S-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF40X800S-08A is a genuine double-acting ISO 15552 cylinder with a Ø40mm bore, 800mm 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 SAIF40X800S-08A
The AirTAC SAIF40X800S-08A is a double-acting ISO 15552 profile cylinder featuring a built-in 4M210-08 5/2 solenoid valve. With a 16.0 mm2 orifice (Cv 0.89) and a 5 cycle/sec max frequency, it delivers 628N of push force at 0.5 MPa. Driven by an AC220V terminal entry coil drawing 3.5 VA, it activates in 0.05 s or less. The cylinder body rates to 1.0 MPa, but because the integrated valve operates at 0.15-0.8 MPa, the practical working range for the assembled SAIF unit is 0.15-0.8 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. This self-contained design eliminates the need for a separate remote valve, drastically reducing panel space and plumbing. The manifold connects to the cylinder via O8 x O5 PU tubing, and this -S variant includes a magnet for CMSE reed and DMSE electronic solid-state sensors.

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 SAIF40X800S-08A Is Used
Decentralized Conveyor Diverters
Ideal for large conveying systems where installing a remote valve island is costly. The integrated 4M210 valve allows each diverter station to switch independently via a single AC220V signal.
Space-Constrained Machinery
Perfect for tight machine layouts. Eliminating the external valve and long pneumatic lines frees up valuable panel space while delivering 628N of push force at 0.5 MPa.
Long-Stroke Material Handling
The 800mm stroke handles extended push-and-pull tasks. The built-in PU tubing (O8 x O5) and self-contained switching simplify installation on moving or widely spaced handling axes.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF40X800S-08A 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 if your load requires more thrust. The self-valved SAIF architecture is ideal for decentralized stations across large machines, saving the cost and complexity of running long valve tubing back to a central manifold. This model uses an AC220V terminal connection with PT threaded ports.
Because the stroke is 800mm, ensure adequate side-load guidance to prevent rod binding. Remember that the 5/2 valve routes air but does not lock the load mechanically—use an AirTAC SAIL lock cylinder if you need true position holding. To replace this unit, match the 40mm bore, 800mm stroke, 1/4" valve port, AC220V voltage, terminal entry, PT threads, and the -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 SAIF40X800S-08A FAQ
At 0.5 MPa, this 40mm bore cylinder provides 628N of push force and 528N of pull force. The integrated 4M210-08 5/2 valve has a 16.0 mm2 effective area (Cv 0.89) and a maximum frequency of 5 cycles per second.
No, it has a built-in 4M210-08 valve. By factory default, the rod retracts when the AC220V coil is energised, but it can be reconfigured to extend-when-energised by repositioning the valve. The practical operating pressure is 0.15-0.8 MPa.
