Airtac SAIF Series Standard Cylinder with Valve SAIF80X350-10B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF80X350-10B 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 SAIF80X350-10B
The AirTAC SAIF80X350-10B is a double-acting ISO 15552 profile cylinder featuring an integrated 4M310-10 5/2 solenoid valve. This specific build uses a DC24V terminal electrical entry and delivers a 30 mm2 effective orifice (Cv 1.68). By mounting the valve directly onto a manifold block via PU tubing, it eliminates the need for a separate remote valve, saving panel space and simplifying decentralized installation across large machines. The cylinder itself features a carbon steel piston rod and PT tapered threads.
While the bare cylinder body rates up to 1.0 MPa, the practical operating range for this assembled SAIF unit is 0.15-0.8 MPa due to the internal pilot valve limits. It delivers robust thrust, generating 2513 N of push force at 0.5 MPa. As a factory setting, the piston rod retracts when the coil is energised, but you can reconfigure the valve position to extend-when-energised if your sequence demands it.

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 SAIF80X350-10B Is Used
Decentralized Assembly Stations
Distributes actuation across large machine layouts without routing long pneumatic lines back to a central manifold.
High-Force Clamping
Provides 2513 N of push force at 0.5 MPa for securing heavy workpieces during machining or joining operations.
Retrofit Automation
Upgrades existing ISO 15552 tooling setups by adding self-switching logic to older cylinders without external plumbing.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF80X350-10B the Right Choice?
Choose this 80mm bore when you need higher force than the 63mm class (which provides 1559 N push at 0.5 MPa) but want to avoid the larger 100mm envelope. The SAIF80X350-10B is ideal for space-constrained machines where running dedicated valve tubing is costly or impractical, as it switches itself from a single DC24V coil signal. It includes variable air cushions at both ends to decelerate the rod near stroke limits, but note that neither the cushion nor the 5/2 valve will hold a load without live pressure. For true position holding, consider the SAIL lock series instead.
When ordering a replacement, verify the 350mm stroke, 3/8" valve port, PT3/8" cylinder port, DC24V voltage, and terminal entry. Because the stroke is 350mm, ensure your mounting arrangement includes adequate guiding to prevent excessive side-loading on the rod.
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 SAIF80X350-10B FAQ
The 80mm bore generates 2513 N of push force and 2268 N of pull force at 0.5 MPa. The built-in 4M310-10 valve provides a 30 mm2 effective orifice with a Cv of 1.68.
No, the 5/2 solenoid valve routes air but does not lock the load without live pressure. By default, the rod retracts when the DC24V coil is energised, but it can be repositioned to extend-when-energised.
