Airtac SAIF Series Standard Cylinder with Valve SAIF80X500S-10A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF80X500S-10A 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-10A
The AirTAC SAIF80X500S-10A is a double-acting ISO 15552 profile cylinder featuring an integrated 4M310-10 5/2 solenoid valve. This built-in valve provides an effective flow area of 30.0 mm2 (Cv 1.68) and connects to the cylinder via a manifold block using PU tubing (O10 x O6.5). Equipped with an AC220V coil utilizing a terminal electrical entry, it consumes 3.5 VA and achieves an IP65-rated response time of 0.05 seconds or less. The carbon steel piston rod includes a magnet for CMSE reed and DMSE electronic sensors.
Because the integrated valve operates at 0.15-0.8 MPa, this defines the practical working pressure range for the assembled unit, even though the bare cylinder rates up to 1.0 MPa. At 0.5 MPa, it delivers 2513 N of push force and 2268 N of pull force. Factory-set to retract the rod when the coil is energised, the valve can be repositioned to extend-when-energised if your logic requires it. This decentralized design eliminates remote plumbing, saving valuable panel space.

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-10A Is Used
Decentralized Automation Stations
Eliminates the need for a remote valve bank on large machines by switching locally from a single AC220V coil signal, drastically reducing tubing runs.
Long-Stroke Material Handling
The 500mm stroke and 2513N push force at 0.5MPa easily move heavy workpieces between machining centers without requiring external pneumatic plumbing.
Space-Constrained Machinery
By mounting the 4M310 valve directly via a manifold block, it frees up electrical panel space and simplifies wiring for compact assembly lines.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF80X500S-10A the Right Choice?
Select this 80mm bore when 50mm bore falls short (delivering only 982 N push at 0.5 MPa) but 100mm is excessive (providing 3927 N). The 500mm stroke suits long-travel handling, but because stroke exceeds 300mm, you must account for side loads and use external guide rails to prevent rod binding. The integrated valve makes it ideal for decentralized stations where running separate valve tubing is costly.
When matching a replacement, verify the 80mm bore, 500mm stroke, PT3/8 cylinder port, 4M310-10 valve port, AC220V voltage, terminal entry, PT thread, and the -S magnet. Remember the 5/2 valve routes air but does not lock the load; for true position holding under pressure loss, specify a SAIL lock or BSAI clamp-lock cylinder.
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-10A FAQ
It delivers 2513 N of push force and 2268 N of pull force at 0.5 MPa. The built-in 4M310-10 valve has an effective area of 30.0 mm2 (Cv 1.68) with a maximum frequency of 4 cycles per second.
No, the 5/2 valve routes air but does not function as a lock or brake. The factory setting retracts the rod when the AC220V coil is energised, but this can be repositioned to extend-when-energised. For true load holding, use a SAIL or BSAI cylinder.
