Airtac SAIF Series Standard Cylinder with Valve SAIF80X350S-10B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF80X350S-10B is a genuine double-acting ISO 15552 cylinder with a Ø80mm bore, 350mm 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 SAIF80X350S-10B
The AirTAC SAIF80X350S-10B is a double-acting ISO 15552 profile cylinder equipped with a built-in 4M310-10 5/2 solenoid valve, delivering a Cv of 1.68 via a 3/8" valve port. Driven by a DC24V terminal entry coil consuming 3.0 W, it activates in 0.05 s. The integrated manifold uses PU10xO6.5 tubing to bridge the valve and the PT3/8" cylinder port. Because the 4M310 valve operates at 0.15-0.8 MPa, the practical working range for this assembled SAIF unit is 0.15-0.8 MPa, even though the bare cylinder rates to 1.0 MPa.
Delivering 2513 N of push force at 0.5 MPa and 4523 N at 0.9 MPa, this 80mm bore actuator switches itself from one coil signal, eliminating remote valves and cutting panel space for decentralized machine stations. Factory set to retract the carbon steel rod when energised, the valve can be repositioned to extend-when-energised. The -S magnet option supports CMSE reed and DMSE electronic sensors for position feedback. Note that the 5/2 valve routes air only; it does not lock the load.

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 SAIF80X350S-10B Is Used
Decentralized Assembly Lines
Ideal for large machines with multiple stations, using the built-in 4M310 valve to cut plumbing and panel space while delivering 2513 N of thrust at 0.5 MPa.
High-Force Clamping Fixtures
Provides 4523 N of push force at 0.9 MPa directly at the work point, driven by a fast 0.05 s DC24V terminal coil without needing a remote valve bank.
Retrofit & Space-Tight Machines
Perfect for upgrades where running new valve tubing is costly, offering a self-switching ISO 15552 profile cylinder with integrated PU10xO6.5 manifold tubing.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF80X350S-10B the Right Choice?
Choose this 80mm SAIF when you need higher mid-range thrust (2513 N at 0.5 MPa) and want to skip a separate valve. If your application requires less force, the 63mm bore offers 1559 N at 0.5 MPa. For heavier loads, the 100mm bore provides 3927 N at 0.5 MPa. The self-valved design excels in decentralized installations where running valve tubing is costly, as one DC24V terminal signal directly controls the cylinder. The 4M310 valve hits a max frequency of 4 cycles/sec.
When replacing this unit, match the 80mm bore, 350mm stroke, 3/8" valve port, DC24V voltage, terminal entry, PT thread, and -S magnet. Because the stroke is 350mm, ensure adequate guide support to prevent rod side-loading and premature seal wear. For applications requiring true load holding without live pressure, consider the AirTAC SAIL lock cylinder instead, as the SAIF air cushion only decelerates near stroke end.
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 SAIF80X350S-10B FAQ
The 80mm bore generates 2513 N of push force at 0.5 MPa and 4523 N at 0.9 MPa. The built-in 4M310-10 5/2 valve provides an effective area of 30.0 mm2 (Cv 1.68) with a 3/8" port.
No, the integrated 4M310 valve switches the cylinder directly from a DC24V terminal coil signal (3.0 W, IP65). By default, the rod retracts when the coil is energised, but you can reposition the valve to extend-when-energised.
