Airtac SAIF Series Standard Cylinder with Valve SAIF80X700S-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF80X700S-08A is a genuine double-acting ISO 15552 cylinder with a Ø80mm bore, 700mm 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 SAIF80X700S-08A
The AirTAC SAIF80X700S-08S is a double-acting ISO 15552 profile cylinder equipped with a built-in 4M310-08 5/2 solenoid valve, delivering a Cv of 1.40 and a 25.0 mm2 effective area. Driven by an AC220V terminal coil consuming 3.5 VA, it achieves IP65 protection and a 0.05 s response. While the cylinder body rates to 1.0 MPa, the integrated valve limits the practical working pressure to 0.15-0.8 MPa. At 0.5 MPa it generates 2513 N of push force.
This assembly eliminates the need for a separate remote valve, using a manifold block and O10 x O6.5 PU tubing to switch itself from one coil signal. Factory set to retract the rod when energised, the valve can be repositioned to extend on signal. The -S magnet supports CMSE reed and DMSE electronic sensors for position feedback.

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)
| Pressure | Push force | Pull force |
|---|---|---|
| 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 SAIF80X700S-08A Is Used
Decentralized Assembly Stations
Eliminates remote valve plumbing on large machines by switching the 2513 N rod directly from an AC220V terminal coil signal.
Automated Material Handling
Uses the built-in 4M310-08 valve and 0.15-0.8 MPa operating range to drive 700mm stroke actuation without dedicated panel space.
Machine Retrofitting
Replaces standard cylinders in tight spaces where running new valve tubing is costly, relying on the O10xO6.5 PU manifold.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF80X700S-08A the Right Choice?
Choose this 80mm bore when a 63mm bore (1402 N pull at 0.5 MPa) lacks the force for heavier handling, but a 100mm bore (3927 N push at 0.5 MPa) is oversized. The self-valved SAIF excels in decentralized stations by cutting panel space and tubing runs. Specify the 4M310-08 valve port (1/4 inch), AC220V voltage, terminal entry, and PT threads for replacements. For the 700mm stroke, add an external guide to prevent side loads from scoring the aluminum profile barrel.
Note that neither the 5/2 valve nor the adjustable air cushions (36 mm) lock or hold a load without live pressure. For true mid-stroke holding, select an AirTAC SAIL pneumatic lock or BSAI clamp-lock cylinder instead of relying on the SAIF.
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 SAIF80X700S-08A FAQ
The 80mm bore generates 2513 N push and 2268 N pull at 0.5 MPa. The built-in 4M310-08 5/2 valve has a 25.0 mm2 orifice with a Cv of 1.40.
No separate valve is needed. The factory setting retracts the rod when the AC220V coil is energised, but repositioning the valve changes it to extend-when-energised.
