Airtac SAIF Series Standard Cylinder with Valve SAIF80X75S-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF80X75S-08A is a genuine double-acting ISO 15552 cylinder with a Ø80mm bore, 75mm 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 SAIF80X75S-08A
The AirTAC SAIF80X75S-08S is a double-acting profile cylinder with a built-in 4M310-08 5/2 solenoid valve, delivering a Cv of 1.40 and a 25mm orifice. Driven by an AC220V coil with a terminal electrical entry, it consumes 3.5 VA and features an IP65 rating with a 0.05s activation time. The integrated manifold uses a PU tube (O10 x O6.5) to bridge the valve and cylinder, meaning the 1/4 valve port and 3/8 cylinder port are distinct. Because the valve operates at 0.15-0.8 MPa, this sets the practical working range for the assembled unit, despite the bare cylinder rating of 1.0 MPa.
This 80mm bore generates 2513N of push force at 0.5 MPa and up to 4523N at 0.9 MPa. It includes a magnet for CMSE reed and DMSE electronic sensors. By default, the piston rod retracts when the coil is energised, but you can reconfigure it to extend-when-energised by repositioning the valve. This self-switching design eliminates remote plumbing, saving panel space for decentralized machine stations.

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 SAIF80X75S-08A Is Used
Decentralized Automation
Ideal for large machines with multiple stations, eliminating the need for a remote valve bank and reducing plumbing complexity.
High-Force Handling
Delivers up to 4523N of push force at 0.9 MPa for heavy clamping and positioning tasks in tight spaces.
Retrofit Stations
Perfect for upgrades where adding dedicated valve tubing is impractical, as it switches directly from one coil signal.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF80X75S-08A the Right Choice?
Choose this 80mm bore when 50mm (982N push at 0.5 MPa) is insufficient but 100mm (3927N at 0.5 MPa) is oversized. The integrated 4M310 valve reaches a max frequency of 4 cycles/sec, making it ideal for high-force decentralized stations where running separate valve tubing is costly. For load-holding, note that the 5/2 valve routes air and does not lock the load; consider SAIL for pneumatic locking. When replacing, match the 80mm bore, 75mm stroke, 1/4 valve port, AC220V terminal coil, PT thread, and -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 SAIF80X75S-08A FAQ
At 0.5 MPa, this 80mm bore cylinder provides 2513N of push force and 2268N of pull force. At 0.9 MPa, the push force reaches 4523N.
Yes. The factory setting retracts the rod when the AC220V coil is energised, but you can reposition the 5/2 valve to extend-when-energised. No separate remote valve is needed.
