Airtac SAIF Series Standard Cylinder with Valve SAIF100X500-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF100X500-08B is a genuine double-acting ISO 15552 cylinder with a Ø100mm bore, 500mm 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 SAIF100X500-08B
The AirTAC SAIF100X500-08B is a double-acting ISO 15552 profile cylinder equipped with a built-in 4M310-08 5/2 solenoid valve, providing a Cv of 1.40 and a 25.0 mm2 orifice. Driven by a DC24V terminal entry coil consuming 3.0 W, it activates in 0.05 s or less with IP65 protection. Although the cylinder body rates to 1.0 MPa, the practical operating range for this valved assembly is 0.15-0.8 MPa. It generates a substantial 3927 N push force at 0.5 MPa, making it suitable for heavy loads.
By default, the piston rod retracts when the coil is energised, but this can be reconfigured to extend-when-energised by repositioning the valve. The integrated manifold uses O10 x O6.5 PU tubing, and the valve port (1/4) differs from the cylinder port (1/2). This self-switching design eliminates the need for remote plumbing, saving panel space and simplifying decentralized installations 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 (Ø100mm)

|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 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 SAIF100X500-08B Is Used
Decentralized Heavy Automation
Ideal for large machines needing isolated heavy push force. The built-in valve removes long tubing runs, letting one DC24V signal drive a 3927 N station directly.
Space-Constrained Pressing
Fits tight retrofit spaces where a remote valve would be impossible. The profile cylinder handles high force while the integrated manifold saves valuable panel space.
Wiring-Simplified Upgrades
Perfect for retrofits where adding pneumatic plumbing is costly. The terminal entry coil allows a single electrical connection to control the entire actuator.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF100X500-08B the Right Choice?
Choose this 100mm bore when the 80mm variant (delivering 2513 N push at 0.5 MPa) is insufficient for your load. The SAIF100X500-08B is optimal for decentralized stations where running separate valve tubing is costly, as one DC24V coil signal drives the cylinder directly. Ensure your system matches the DC24V terminal electrical entry and PT tapered threads. If you need load holding without live pressure, note that the 5/2 valve routes air but does not lock; consider the SAIL or BSAI series for clamp-lock requirements.
At 500 mm stroke, prevent rod sag and side-load damage by using a dedicated guide rail to support the load. For replacement, verify the 100mm bore, 500mm stroke, 1/4 valve port, DC24V voltage, terminal entry, PT thread, and absence of a magnet. Sensors require adding the -S option to work with CMSE reed or DMSE electronic switches.
Quick checklist
