Airtac SAIF Series Standard Cylinder with Valve SAIF80X500S-10B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF80X500S-10B is a genuine double-acting ISO 15552 cylinder with a Ø80mm bore, 500mm stroke and a built-in 4M310-10 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 SAIF80X500S-10B
The AirTAC SAIF80X500S-10B is a double-acting ISO 15552 profile cylinder featuring an integrated 4M310-10 5/2 solenoid valve. This specific build pairs a 500mm stroke with a carbon steel rod and includes a magnet for CMSE reed and DMSE electronic sensors. Driven by a DC24V terminal coil drawing 3.0 W, the valve offers a 30.0 mm2 orifice (Cv 1.68) and switches up to 4 cycles per second. Because the cylinder body rates to 1.0 MPa but the internal pilot valve operates at 0.15-0.8 MPa, the practical working pressure for this assembled unit is 0.15-0.8 MPa.
Generating 4523N of push force at 0.9 MPa, this self-switching unit eliminates the need for a separate remote valve. The manifold connects the valve to the cylinder using PU tubing (O10 x O6.5), and it is crucial to note the valve port is 3/8" while the cylinder port is also 3/8". Factory set to retract the piston rod when the coil is energised, the valve can be repositioned to extend-when-energised if your logic requires it. The 5/2 valve holds position via internal pilot pressure, not a spring, meaning it will not hold a 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.
Theoretical Output Force (Ø80mm)

| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 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 SAIF80X500S-10B Is Used
Decentralized Automation
Perfect for large factory layouts where installing a central valve bank is impractical, letting this 80mm cylinder control itself via a single DC24V signal.
High-Force Clamping
Delivers 4523N of push force at 0.9 MPa for securing heavy workpieces during machining, without needing external plumbing to a remote valve.
Retrofit Upgrades
Ideal for upgrading older machines where routing new pneumatic tubing is costly; the built-in 4M310 valve and terminal entry simplify electrical wiring.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF80X500S-10B the Right Choice?
Choose this 80mm bore if you need higher thrust than the 63mm bore (which provides 2805N push at 0.9 MPa) but do not require the 7068N force of the 100mm option. A self-valved SAIF is ideal for decentralized stations across large machines where running separate valve tubing wastes space and wiring. For this 500mm stroke, adding an external guide is recommended to prevent excessive side-load wear on the cylinder seals. Remember the air cushion only decelerates the rod near stroke end; for true load-holding, select a SAIL lock or BSAI clamp-lock cylinder. When replacing, match the 80mm bore, 500mm stroke, 3/8" valve port, DC24V voltage, terminal entry, 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 SAIF80X500S-10B FAQ
The 80mm bore generates 4523N of push force and 2268N of pull force at 0.9 MPa. The built-in 4M310-10 valve has a 30.0 mm2 effective area (Cv 1.68) and a maximum frequency of 4 cycles per second.
No, the SAIF80X500S-10B switches itself from one DC24V coil signal. By default, the piston rod retracts when the coil is energised, but it can be reconfigured to extend-when-energised by repositioning the valve.
