Airtac SAIF Series Standard Cylinder with Valve SAIF100X800S-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF100X800S-08B is a genuine double-acting ISO 15552 cylinder with a Ø100mm 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 SAIF100X800S-08B
The AirTAC SAIF100X800S-08B is a double-acting ISO 15552 profile cylinder featuring an integrated 4M310-08 5/2 solenoid valve. Equipped with a DC24V terminal coil consuming 3.0 W, it delivers a robust 3927N push force at 0.5 MPa. The built-in valve offers a Cv of 1.40 and operates at 4 cycles per second, driving the assembly directly from one electrical signal.
Because the 5/2 valve limits the working pressure to 0.15-0.8 MPa, the practical operating range sits below the bare cylinder's 1.0 MPa rating. The factory setting retracts the rod when the coil is energised, but you can reposition the valve to extend on signal. This self-contained design eliminates remote valves and excess tubing, making it ideal for decentralized machine stations. The manifold connects to the cylinder via PU tubing (O10 x O6.5), and the -S magnet supports CMSE reed and DMSE electronic sensors.

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 SAIF100X800S-08B Is Used
Decentralized Automation
Eliminates the need for a remote valve bank on large machines, driving heavy 100mm bore actuators directly from a local DC24V signal.
Heavy Material Handling
Provides high push force (3927N at 0.5 MPa) for moving substantial workpieces over an 800mm travel distance without external tubing.
Space-Constrained Retrofits
Ideal for upgrading existing ISO 15552 assemblies where running new valve tubing is costly or panel space is fully utilized.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF100X800S-08B the Right Choice?
Choose this 100mm bore when you need heavy thrust (up to 3927N at 0.5 MPa or 801 kgf max) over an 800mm stroke. If your application requires less force, stepping down to the 80mm bore yields 2513N push at 0.5 MPa, which may save space and air consumption. The integrated 4M310-08 valve uses a 1/4" port, while the cylinder itself features a 1/2" thread, so ensure your fittings match the valve inlet precisely.
For an 800mm stroke, guiding the load is critical to prevent side-load wear on the seals and barrel. This self-valved unit removes the need for a separate panel valve, saving significant plumbing and wiring time. Remember that the 5/2 valve routes air but does not lock the load; if you need true position holding without live pressure, consider the AirTAC SAIL lock cylinder or BSAI clamp-lock series instead. Replacement requires matching the 100mm bore, 800mm stroke, 1/4" valve port, DC24V terminal coil, PT threads, and the -S 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 SAIF100X800S-08B FAQ
The 100mm bore generates 3927N push force (3681N pull) at 0.5 MPa, with a maximum force of 801 kgf at 1.0 MPa. The built-in 4M310-08 valve has an effective area of 25.0 mm2 (Cv 1.40) and a maximum operating frequency of 4 cycles per second.
No, the 5/2 valve routes air but does not lock the rod mechanically; you need live pressure to hold position. It uses a DC24V terminal coil (3.0 W, IP65). By factory default, the rod retracts when the coil is energised, but you can reposition the valve to extend-when-energised.
