Airtac SAIF Series Standard Cylinder with Valve SAIF80X700S-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF80X700S-08B 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-08B
The AirTAC SAIF80X700S-08B is a double-acting ISO 15552 profile cylinder equipped with a built-in 4M310-08 5/2 solenoid valve, providing a Cv of 1.40 and an effective area of 25.0 mm2. Driven by a DC24V terminal entry coil consuming 3.0 W, it achieves IP65 protection and responds within 0.05 s. While the cylinder body rates to 1.0 MPa, the integrated valve limits the practical operating pressure to 0.15-0.8 MPa, operating across a 30-800 mm/s speed range.
Featuring a carbon steel piston rod and an -S magnet for CMSE reed or DMSE electronic sensors, this unit delivers 2513 N of push force at 0.5 MPa. The factory default setting retracts the rod when the coil is energised, but you can reconfigure it to extend-when-energised simply by repositioning the valve. The manifold connects to the cylinder via O10 x O6.5 PU tubing, meaning the 1/4" valve port and the cylinder's 3/8" port are distinctly separate.

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 SAIF80X700S-08B Is Used
Decentralized Automation
Perfect for large-scale machinery where running remote valve tubing is costly. The integrated 4M310-08 valve lets this 80mm cylinder switch itself from a single DC24V signal.
Long-Stroke Assembly
With a 700mm stroke and 2513 N push force at 0.5 MPa, it handles extended material push or transfer tasks while keeping panel wiring to a minimum.
Space-Constrained Retrofit
Ideal for upgrading older machines where external valve islands lack physical space. The built-in valve and terminal coil simplify electrical hookups.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF80X700S-08B the Right Choice?
Choose this self-valved SAIF80X700S-08B to eliminate remote plumbing and panel space, making it ideal for decentralized stations across large machines. If your application requires less force, stepping down to a 63mm bore yields 1559 N of push at 0.5 MPa; conversely, stepping up to 100mm provides 3927 N. Because the stroke is 700 mm, you must account for side-load risks and use appropriate guide rails to prevent rod binding.
Remember that the built-in 5/2 valve routes air but does not lock the load—without live pressure, the cylinder will not hold its position. For true mechanical load-holding, consider the SAIL lock or BSAI clamp-lock variants. When ordering a replacement, verify the 80mm bore, 700mm stroke, 1/4" valve port, DC24V voltage, terminal entry, PT thread, and -S magnet.
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-08B FAQ
The 80mm bore generates 2513 N of push force and 2268 N of pull force at 0.5 MPa. The built-in 4M310-08 valve has a Cv of 1.40, an effective area of 25.0 mm2, and a maximum frequency of 4 cycles per second.
No separate valve is needed. The cylinder switches itself via the integrated 4M310 5/2 valve using a DC24V terminal coil. By factory default, the piston rod retracts when the coil is energised, but you can reposition the valve to extend-when-energised.
