Airtac SAIF Series Standard Cylinder with Valve SAIF40X800-06B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF40X800-06B 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 SAIF40X800-06B
The AirTAC SAIF40X800-06B is a double-acting ISO 15552 profile cylinder featuring an integrated 4M210-06 5/2 solenoid valve. This specific SKU is configured with a DC24V terminal electrical entry consuming 3.0 W, a PT1/8 cylinder port, and a valve port code of 06 (1/8). The built-in valve provides an effective flow area of 14.0 mm2 (Cv 0.78). Because the valve manifold routes air internally via an O8xO5 PU tube, you eliminate remote plumbing and save panel space, making it highly effective for decentralized machine stations.
While the bare cylinder body is rated for up to 1.0 MPa, the practical operating pressure for this assembled SAIF unit is 0.15-0.8 MPa due to the internal pilot valve limits. Operating at 0.5 MPa yields a push force of 628N and a pull force of 528N. From the factory, the default setting retracts the piston rod when the coil is energised, but you can reconfigure it to extend-when-energised simply by repositioning the valve. The unit relies on a 5/2 pilot-held valve design and variable air cushions at both ends to decelerate near stroke end, but it does not lock or hold the load without live air pressure.

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.

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 SAIF40X800-06B Is Used
Decentralized Automation
Eliminates the need for long tubing runs back to a central valve island, driving the 628N rod directly from a local DC24V signal across large factory layouts.
Extended Stroke Sorting
The 800mm stroke and integrated 4M210-06 valve provide compact actuation for diverting packages on space-constrained conveyor lines without remote plumbing.
Retrofit Control Systems
Ideal for upgrading older machines where adding a new valve manifold is costly, utilizing the built-in 5/2 valve and terminal entry for a fast, localized wiring connection.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF40X800-06B the Right Choice?
Choose this self-valved SAIF40X800-06B when a decentralized station requires 628N of push force at 0.5 MPa and you want to avoid the wiring and tubing complexity of a separate remote valve. If your application demands significantly less force, stepping down to a 32mm bore provides 402N push force; if you need more thrust, stepping up to a 50mm bore yields 982N. The DC24V terminal coil offers IP65 protection and a 0.05s activation time, suitable for standard industrial control panels.
Because this model features an 800mm stroke, which exceeds the 300mm threshold, you must account for potential side-loading and use external guide rails to prevent rod damage and premature seal wear. When ordering a replacement, verify the 40mm bore, 800mm stroke, 4M210-06 valve build, DC24V voltage, terminal entry, PT thread, and the absence of a sensor magnet. For any load-holding requirements, note that the 5/2 valve only routes air and is not a brake; consider an AirTAC SAIL lock cylinder instead.
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 SAIF40X800-06B FAQ
At 0.5 MPa, this 40mm bore cylinder delivers 628N of push force and 528N of pull force. The integrated 4M210-06 valve has an effective flow area of 14.0 mm2 (Cv 0.78) and supports a maximum frequency of 5 cycles per second.
No, the 5/2 solenoid valve routes air but does not function as a lock or brake. The factory default setting retracts the rod when the DC24V coil is energised, but it can be reconfigured to extend-when-energised by repositioning the valve. For true load holding, a SAIL lock cylinder is required.
