Airtac SAIF Series Standard Cylinder with Valve SAIF80X200S-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF80X200S-08A is a genuine double-acting ISO 15552 cylinder with a Ø80mm bore, 200mm 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 SAIF80X200S-08A
The AirTAC SAIF80X200S-08S is a double-acting ISO 15552 profile cylinder featuring a built-in 4M310-08 5/2 solenoid valve. With a 1.40 Cv flow coefficient, this unit delivers 2513N push force at 0.5 MPa. It includes a magnet for CMSE reed and DMSE electronic sensors. The AC220V terminal coil consumes 3.5 VA and responds in 0.05s. Because the valve operates at 0.15-0.8 MPa, this defines the practical working pressure for the assembly.
The integrated valve manifold uses O10xO6.5 PU tubing to connect to the cylinder. By default, the piston rod retracts when the coil is energised, but you can reposition the valve to extend-when-energised. This self-switching design eliminates remote plumbing, making it ideal 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 SAIF80X200S-08A Is Used
Decentralized Assembly Lines
Perfect for large machines where running air tubing to a central valve bank is costly. The integrated valve allows local control via a single electrical signal.
High-Force Clamping Stations
Delivers 2513N of push force at 0.5 MPa, suitable for securing heavy workpieces during machining operations without needing external valving.
Space-Constrained Machinery
The profile barrel and manifold block minimize envelope size, fitting easily into tight automation cells where panel space is restricted.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF80X200S-08A the Right Choice?
Select this 80mm bore model when a 63mm bore (providing 1559N push at 0.5 MPa) is insufficient, but a 100mm bore is too large. The self-contained 4M310-08 valve removes the need for a separate panel valve, cutting tubing costs and wiring complexity. The cylinder port is 3/8 inch, while the valve port is 1/4 inch.
Note that the 5/2 valve routes air but does not lock the load; for position holding, consider the SAIL series. At 200mm stroke, side loads are moderate, but ensure adequate guiding for longer strokes. To replace this unit, match the 80mm bore, 200mm stroke, 1/4 inch 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 SAIF80X200S-08A FAQ
At 0.5 MPa, this 80mm bore cylinder provides 2513N of push force and 2268N of pull force. The integrated 4M310-08 valve has a 1.40 Cv flow coefficient to handle the required air volume.
No, the 5/2 solenoid valve routes air but does not lock the load. The factory setting retracts the rod when the AC220V coil is energised, but it can be repositioned to extend-when-energised. For true position holding, use the SAIL series.
