Airtac SAIF Series Standard Cylinder with Valve SAIF80X335S-10C
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF80X335S-10C is a genuine double-acting ISO 15552 cylinder with a Ø80mm bore, 335mm 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 SAIF80X335S-10C
The AirTAC SAIF80X335S-10C is a double-acting ISO 15552 profile cylinder with a built-in 4M310-10 5/2 solenoid valve, delivering a Cv of 1.68 and an effective orifice of 30.0 mm2. Driven by an AC110V terminal coil drawing 3.5 VA, it eliminates remote plumbing by switching itself from a single electrical signal. Because the cylinder body rates to 1.0 MPa but the internal pilot valve is limited to 0.15-0.8 MPa, the practical operating range for this assembled unit is 0.15-0.8 MPa.
At 0.5 MPa it generates 2513 N of push force and 2268 N of pull force, scaling to 4523 N push at 0.9 MPa. The manifold connects to the cylinder via O10 x O6.5 PU tubing, and the valve port (3/8 inch) differs from the cylinder port (also 3/8 inch). Factory-set to retract the rod when energised, the valve can be repositioned to extend on signal. This unit includes a magnet for CMSE reed and DMSE electronic sensors.

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 SAIF80X335S-10C Is Used
Decentralized Machine Stations
Ideal for large machines with multiple stations, eliminating long valve tubing runs by mounting the 4M310 valve directly on the cylinder.
High-Force Clamping
Provides 2513 N of push force at 0.5 MPa for heavy-duty clamping and holding tasks in automated assembly lines.
Space-Constrained Retrofits
Fits into tight envelopes where a separate valve island would not fit, simplifying wiring with its AC110V terminal connection.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF80X335S-10C the Right Choice?
Select this 80mm bore when a 63mm bore falls short of the 2182 N push force at 0.5 MPa, or step down to 63mm if 1559 N is sufficient. The self-valved SAIF design excels over a separate cylinder and remote valve in decentralized stations, cutting panel space and tubing runs. The AC110V terminal coil offers IP65 protection and a 0.05 s response time. Stroke is 335mm; for any stroke over 300mm, use a guide to prevent side loads and ensure seal longevity. To replace: match 80mm bore, 335mm stroke, 3/8 inch valve port, AC110V, terminal entry, PT thread, and the -S magnet.
Remember that the 5/2 valve routes air but does not lock the load; without live pressure the rod will move. The air cushion only decelerates near stroke end. For true position holding, consider an AirTAC SAIL pneumatic 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 SAIF80X335S-10C FAQ
The 80mm bore generates 2513 N push and 2268 N pull force at 0.5 MPa, reaching 4523 N push at 0.9 MPa. The built-in 4M310-10 valve has a 30.0 mm2 orifice with a Cv of 1.68 and a max frequency of 4 cycles per second.
The integrated 5/2 valve is factory-set to retract the rod when the AC110V coil is energised, but can be reconfigured to extend on signal. It routes air to switch the cylinder but does not lock the load without live pressure; use a SAIL lock cylinder for position holding.
