Airtac SAIF Series Standard Cylinder with Valve SAIF80X800S-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF80X800S-08B is a genuine double-acting ISO 15552 cylinder with a Ø80mm bore, 800mm stroke and a built-in 4M310-08 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 SAIF80X800S-08B
The AirTAC SAIF80X800S-08B is a double-acting ISO 15552 profile cylinder featuring an integrated 4M310-08 5/2 solenoid valve. This specific SKU is configured with a DC24V terminal electrical entry drawing 3.0 W, a PT1/4 valve port, and a carbon steel piston rod. The built-in valve provides an effective flow area of 25.0 mm2 (Cv 1.40) and cycles up to 4 times per second. Because the valve manifold is mounted directly to the profile barrel using O10 x O6.5 PU tubing, it eliminates the need for a separate remote valve, saving panel space and simplifying decentralized station wiring across large machines.
While the bare cylinder is rated for 1.5 MPa proof pressure, the practical operating range for this assembled SAIF unit is 0.15-0.8 MPa due to the internal pilot valve limits. It delivers 2513 N of push force at 0.5 MPa. Factory-set to retract the rod when the coil is energised, the valve can be repositioned to extend-when-energised if your sequence requires it. The included -S magnet enables position detection with AirTAC CMSE reed or DMSE electronic solid-state sensors in the dual side grooves.

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 SAIF80X800S-08B Is Used
Large Machine Decentralization
Ideal for sprawling assembly lines where routing individual air lines back to a central manifold is impractical, letting the 80mm bore actuate locally from a single DC24V signal.
Space-Constrained Automation
Perfect for tight cell layouts where panel space is at a premium, as the built-in 4M310 valve removes the need to mount a separate remote valve bank nearby.
Retrofit & Upgrades
Simplifies older machine upgrades by replacing a standard cylinder and external plumbing with a self-switching unit, drastically reducing pneumatic tubing costs.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF80X800S-08B the Right Choice?
Choose this 80mm bore when you need substantial thrust (2513 N push at 0.5 MPa) but want to avoid the plumbing of a remote valve. If your application requires less force, stepping down to a 63mm bore yields 1559 N push at 0.5 MPa; stepping up to 100mm provides 3927 N. The integrated 4M310-08 valve handles its own switching from one DC24V signal, which is ideal for space-tight machines where running air tubing back to a manifold is costly. Note that the 5/2 valve routes air and is not a lock; the air cushion only decelerates near stroke end. For true load-holding, consider an SAIL lock cylinder. Replacement matches must specify bore 80, stroke 800, PT1/4 valve port, DC24V, terminal entry, PT thread, and the -S magnet.
Because the 800mm stroke exceeds 300mm, ensure adequate guide support to prevent excessive side-loading on the piston rod. The cylinder speed operates between 30-800 mm/s, and the DC24V coil offers IP65 protection with a fast 0.05 s activation time.
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 SAIF80X800S-08B FAQ
At 0.5 MPa, this 80mm bore cylinder provides 2513 N of push force and 2268 N of pull force. The integrated 4M310-08 5/2 valve has an effective area of 25.0 mm2 (Cv 1.40) to handle the required air volume.
No, the 4M310 valve is built-in and switches itself from the DC24V terminal coil signal. By default, the rod retracts when energised, but you can reposition the valve to extend-when-energised if needed.
