Airtac SAIF Series Standard Cylinder with Valve SAIF80X400-10B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF80X400-10B is a genuine double-acting ISO 15552 cylinder with a Ø80mm bore, 400mm 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 SAIF80X400-10B
The AirTAC SAIF80X400-10B is a double-acting ISO 15552 profile cylinder featuring an integrated 4M310-10 5/2 solenoid valve. This built-in valve provides an effective flow of 30.0 mm2 (Cv 1.68) and operates at 4 cycles per second. Equipped with a DC24V terminal coil consuming 3.0 W, it offers IP65 protection and a rapid 0.05 s activation time. Because the valve manifold mounts directly to the cylinder using O10 x O6.5 PU tubing, you save panel space and eliminate remote plumbing.
The cylinder bore is 3/8" PT tapered, while the valve port is 3/8". Although the cylinder body rates to 1.0 MPa, the practical working range for this valved assembly is 0.15-0.8 MPa. Generating 2513 N push force at 0.5 MPa, it handles heavy loads. Factory set to retract the rod when energised, the valve can be repositioned to extend-when-energised. The carbon steel rod and standard seals suit 30-800 mm/s speeds.

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)

| 0.7 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 SAIF80X400-10B Is Used
Decentralized Automation
Perfect for large machine grids where running individual valve tubing back to a central panel is costly and space-prohibitive.
Heavy Material Handling
Provides 2513 N of push force at 0.5 MPa for moving substantial jigs or parts directly at the workstation.
Retrofit Upgrades
Ideal for upgrading existing ISO 15552 assemblies by adding self-switching capability without major pneumatic redesign.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF80X400-10B the Right Choice?
Choose this self-valved SAIF80X400-10B when decentralizing large machine stations, as one DC24V signal drives the cylinder without a separate remote valve. If your application requires less force, step down to the 63 mm bore, which yields 1559 N push at 0.5 MPa. For higher force, the 100 mm bore offers 3927 N at 0.5 MPa. This unit uses a DC24V terminal entry and PT threads. Remember that the 5/2 valve routes air but does not lock the load; for position holding, consider the SAIL lock cylinder. Because the stroke is 400 mm, add an external guide to prevent side-load wear on the seals.
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 SAIF80X400-10B FAQ
The 80 mm bore generates 2513 N push and 2268 N pull force at 0.5 MPa. The built-in 4M310-10 valve has a 30.0 mm2 orifice with a Cv of 1.68.
No remote valve is needed; the integrated 5/2 valve switches the cylinder from one DC24V coil signal. The factory setting retracts the rod when energised, but you can reposition the valve to extend-when-energised.
