Airtac SAIF Series Standard Cylinder with Valve SAIF80X125S-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF80X125S-08A is a genuine double-acting ISO 15552 cylinder with a Ø80mm bore, 125mm 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 SAIF80X125S-08A
The AirTAC SAIF80X125S-08A is a double-acting profile cylinder with a built-in 4M310-08 5/2 solenoid valve, delivering a Cv of 1.40 and an effective area of 25.0 mm2. Driven by an AC220V terminal coil consuming 3.5 VA, it switches itself from a single electrical signal, eliminating remote valve plumbing. The -S magnet option enables position tracking with CMSE reed or DMSE electronic sensors.
Although the ISO 15552 interchangeable barrel rates to 1.0 MPa, the internal piloted valve limits the practical SAIF operating pressure to 0.15-0.8 MPa. At 0.5 MPa this 80mm bore generates 2513N of push force and 2268N of pull force. Factory set to retract when energised, the valve can be repositioned to extend on signal, using PU tubing (O10xO6.5) to link the manifold block.

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 SAIF80X125S-08A Is Used
Decentralized Assembly Lines
Ideal for large machines with distributed stations, eliminating the need to route long valve tubing back to a central panel.
High-Force Clamping
Delivers 2513N of push force at 0.5 MPa for securing heavy workpieces during machining operations.
Space-Constrained Retrofits
The integrated manifold block saves valuable panel space in compact machinery upgrades where a separate valve would not fit.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF80X125S-08A the Right Choice?
Choose this 80mm bore when 50mm (982N push at 0.5 MPa) is insufficient, or step down to 63mm (1559N push) if 2513N is excessive. The self-contained 4M310-08 valve makes it ideal for decentralized stations where running separate air lines is costly, though it cannot hold loads unpowered—use SAIL for locking. Verify your replacement needs: 80mm bore, 125mm stroke, PT1/4 cylinder port, 1/4 valve port, AC220V terminal coil, 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 SAIF80X125S-08A FAQ
The 80mm bore generates 2513N push and 2268N pull force at 0.5 MPa. The built-in 4M310-08 valve provides an effective area of 25.0 mm2 (Cv 1.40) with a max frequency of 4 cycles/sec.
It uses an AC220V terminal coil (3.5 VA, IP65, 0.05s response). By default, the piston retracts when the coil is energised, but this can be reconfigured to extend-when-energised by repositioning the valve.
