Airtac SAIF Series Standard Cylinder with Valve SAIF40X800S-06B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF40X800S-06B is a genuine double-acting ISO 15552 cylinder with a Ø40mm bore, 800mm 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 SAIF40X800S-06B
The AirTAC SAIF40X800S-06B is a double-acting ISO 15552 profile cylinder featuring an integrated 4M210-06 5/2 solenoid valve. Equipped with a DC24V terminal coil consuming 3.0 W, it delivers a Cv of 0.78 and generates 628N of push force at 0.5 MPa. The assembly operates within a 0.15-0.8 MPa range, as the built-in valve limits the 1.0 MPa cylinder rating. A pre-installed magnet enables position sensing with CMSE reed and DMSE electronic switches.
By default, the piston rod retracts when the coil is energised, but you can reconfigure it to extend-when-energised by repositioning the valve. This decentralized design eliminates remote plumbing, routing air directly through a PU tube (O8xO5) to the cylinder port, saving panel space 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)

| 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-06B Is Used
Decentralized Assembly Lines
Eliminates the need for a central valve manifold, reducing tubing runs and panel space across large-scale automated manufacturing equipment.
Long-Stroke Material Handling
Provides reliable 800mm travel for pushing or indexing products on a conveyor, guided by external rails to handle the extended stroke length.
Space-Tight Machine Retrofits
Ideal for upgrading existing machinery where running new pneumatic lines to a remote valve bank is structurally difficult or costly.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF40X800S-06B the Right Choice?
Choose this 40mm bore when 32mm lacks thrust (402N at 0.5 MPa) or 50mm is excessive (982N at 0.5 MPa). The 800mm stroke suits long-travel handling, but at this length you must account for rod side-loading and use external guide rails to prevent binding. The self-valved architecture is superior to a separate cylinder and remote valve when minimizing wiring and tubing in decentralized stations is critical.
To replace this unit, match the 40mm bore, 800mm stroke, 4M210-06 valve (1/8" valve port), PT1/4" cylinder port, DC24V voltage, terminal entry, and the -S magnet. Remember that the 5/2 valve routes air but does not lock the load; for position holding without live pressure, consider the 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 SAIF40X800S-06B FAQ
At 0.5 MPa, this 40mm bore cylinder provides 628N of push force and 528N of pull force. The built-in 4M210-06 valve has an effective area of 14.0 mm2 (Cv 0.78) and supports a maximum frequency of 5 cycles per second.
No, the 5/2 valve routes air but does not lock the load without live pressure. The DC24V terminal coil draws 3.0 W with an IP65 rating. Factory-set to retract when energised, the valve can be repositioned to extend-when-energised, allowing one signal to drive the cylinder independently.
