Airtac SAIF Series Standard Cylinder with Valve SAIF40X635S-06E
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF40X635S-06E is a genuine double-acting ISO 15552 cylinder with a Ø40mm bore, 635mm 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 SAIF40X635S-06E
The AirTAC SAIF40X635S-06E is a double-acting ISO 15552 profile cylinder equipped with a built-in 4M210-06 5/2 solenoid valve. This integrated manifold uses an O8xO5 PU tube to link the valve block to the cylinder, meaning the unit switches itself from one coil signal without needing remote plumbing. Driven by an AC24V terminal entry coil drawing 3.5 VA, it responds in 0.05s and carries an IP65 rating. The valve offers a 14.0 mm2 effective area (Cv 0.78) and cycles up to 5 times per second.
Because the cylinder body rates to 1.0 MPa but the internal pilot 5/2 valve operates at 0.15-0.8 MPa, the practical working pressure for this assembled SAIF unit is 0.15-0.8 MPa. At 0.5 MPa the 40mm bore delivers 628N of push force and 528N of pull force. The factory setting retracts the rod when the coil is energised, but you can reposition the valve to extend-when-energised. This unit includes a magnet for CMSE reed and DMSE electronic 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)
| 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 SAIF40X635S-06E Is Used
Decentralized Assembly Stations
Eliminates the need for a remote valve bank on large multi-station machines, driving the 40mm bore directly from its integrated 4M210 valve via an AC24V signal.
Space-Constrained Diverters
Ideal for tight machinery envelopes where running separate valve tubing is costly, using the built-in manifold and short PU tube to self-switch the diverter cylinder.
Retrofitted Automation Lines
Simplifies upgrades on existing conveyors by providing a self-contained ISO 15552 actuator that responds in 0.05s without adding new pneumatic panels.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF40X635S-06E the Right Choice?
Choose this self-valved SAIF assembly when installing decentralized stations across a large machine, as it eliminates separate valve panels and reduces tubing runs. If your application requires less force, stepping down to a 32mm bore yields 402N of push at 0.5 MPa. If you need higher flow or greater thrust, a 50mm bore provides 982N push at 0.5 MPa and pairs with a larger 4M210-08 port. This specific SKU features a PT1/8 valve port, PT1/4 cylinder port, and a carbon steel rod. For replacement, verify the 635mm stroke, AC24V voltage, terminal entry, and -S magnet. Because the 635mm stroke is relatively long, ensure adequate guide support to prevent rod side-loading and premature seal wear. Note that the 5/2 valve routes air but does not lock the load; for position holding, consider an AirTAC SAIL lock cylinder.
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 SAIF40X635S-06E FAQ
The 40mm bore generates 628N push and 528N pull force at 0.5 MPa. The integrated 4M210-06 valve has a 14.0 mm2 effective area (Cv 0.78) and supports a maximum frequency of 5 cycles per second.
Yes, the SAIF series features a built-in 5/2 solenoid valve that switches the cylinder directly from an AC24V terminal coil signal. By factory default, the piston retracts when energised, but you can reposition the valve to extend-when-energised.
