Airtac SAIF Series Standard Cylinder with Valve SAIF40X80S-06B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF40X80S-06B is a genuine double-acting ISO 15552 cylinder with a Ø40mm bore, 80mm 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 SAIF40X80S-06B
The AirTAC SAIF40X80S-06B is a double-acting profile cylinder with an integrated 4M210-06 5/2 solenoid valve, delivering a 628N push force at 0.5 MPa. It bundles the actuator and valve into one unit, using an O8xO5 PU tube manifold to eliminate remote plumbing. Driven by a DC24V terminal coil drawing 3.0W, it switches itself with a 0.05s response time. The base cylinder is dimensionally interchangeable per ISO 15552 standards.
While the cylinder body rates to 1.0 MPa, the built-in valve limits the practical operating range to 0.15-0.8 MPa. By default, the piston rod retracts when the coil is energised, but you can reposition the valve to extend-when-energised. Equipped with a magnet (-S), it supports CMSE reed and DMSE electronic sensors for position feedback.

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 SAIF40X80S-06B Is Used
Decentralized Assembly Stations
Ideal for large machines where running individual valve lines is costly, letting each 40mm cylinder switch itself via a single DC24V signal.
Compact Clamping Jigs
The integrated 4M210-06 valve saves panel space while delivering 528N of pull force at 0.5 MPa for secure workholding.
Sensor-Ready Positioning
The -S magnet works directly with DMSE solid-state switches, ensuring reliable end-of-stroke detection in automated material handling.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF40X80S-06B the Right Choice?
Choose this self-valved unit when you need decentralized control across large machines, as it removes the need for a separate panel valve and extensive tubing. If your application requires less force, stepping down to a 32mm bore yields 402N push at 0.5 MPa; if you need more power, a 50mm bore provides 982N. Remember that the 5/2 valve routes air but does not lock the load—use SAIL or BSAI cylinders for holding tasks. For stroke lengths of 300mm or more, add an external guide to prevent side-load damage. Replacement matches require a 40mm bore, 80mm stroke, 1/8" valve port, DC24V terminal coil, PT threads, and a 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 SAIF40X80S-06B FAQ
The built-in 4M210-06 valve has a 14.0 mm2 effective area (Cv 0.78). The 40mm bore cylinder generates 628N push and 528N pull force at 0.5 MPa.
Yes. The factory setting retracts the rod upon energisation, but you can reconfigure the 5/2 valve to extend-when-energised. This built-in design means no separate remote valve is needed.
