Airtac SAIF Series Standard Cylinder with Valve SAIF80X100S-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF80X100S-08A is a genuine double-acting ISO 15552 cylinder with a Ø80mm bore, 100mm 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 SAIF80X100S-08A
The AirTAC SAIF80X100S-08A is a double-acting profile cylinder dimensionally interchangeable per ISO 15552, featuring a carbon steel piston rod and an integrated 4M310-08 5/2 solenoid valve. This built-in valve delivers a Cv of 1.40 and operates at up to 4 cycles per second, driving the 80mm bore to generate 2513N of push force at 0.5MPa. Equipped with a magnet for CMSE reed and DMSE electronic sensors, it uses an AC220V terminal coil drawing 3.5VA with an IP65 rating and a 0.05s response time.
Because the 4M310 valve handles the air routing directly at the manifold block via PU tubing, you eliminate remote plumbing and save panel space for decentralized machine stations. The bare cylinder rates to 1.0MPa, but the integrated valve limits the practical SAIF operating pressure to 0.15-0.8MPa. By factory default, the piston rod retracts when the coil is energised, but you can reposition the valve to extend-when-energised. The 5/2 pilot holds position pneumatically, not via a spring, and the air cushions only decelerate the load near stroke end without mechanically locking it.

| 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 SAIF80X100S-08A Is Used
Decentralized Automation Cells
Ideal for large machines with multiple stations, bringing the 5/2 valve control directly to the 80mm cylinder to minimize pneumatic tubing and electrical wiring across the plant floor.
Heavy-Duty Pressing
Delivers 4523N of push force at 0.9MPa for clamping or pressing heavy assemblies, utilizing the built-in 4M310-08 valve for rapid 4 cycle/sec actuation.
Space-Constrained Retrofits
Perfect for upgrading older machines where adding a remote valve manifold is impractical, leveraging the integrated PT1/4 ported valve and AC220V terminal coil for a compact footprint.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF80X100S-08A the Right Choice?
Select this 80mm bore when your application requires substantial thrust, such as the 2513N push force at 0.5MPa or 4523N at 0.9MPa. If your fixture needs less force, step down to the 63mm bore (1559N push at 0.5MPa) to save envelope size and air volume. The SAIF80X100S-08A excels over a separate cylinder and remote valve setup by consolidating control locally, which drastically reduces tubing runs and wiring complexity across large machines.
When ordering a replacement, verify the 100mm stroke, 4M310-08 valve port (1/4"), AC220V terminal coil, PT threaded ports, and the -S magnet for CMSE/DMSE sensors. Since the stroke is under 300mm, standard mounting options like FA, FB, or TC foot and flange brackets are straightforward without needing auxiliary side-load guides. Remember that for any load-holding requirements during air loss, this 5/2 valve does not lock the rod; you would need to specify a SAIL pneumatic lock or BSAI clamp-lock cylinder instead.
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 SAIF80X100S-08A FAQ
The 80mm bore generates 2513N push force at 0.5MPa and 4523N at 0.9MPa. The built-in 4M310-08 5/2 valve provides an effective area of 25.0mm2 (Cv 1.40) and supports a maximum frequency of 4 cycles per second.
The integrated 4M310 valve is a 5/2 pilot-operated solenoid that holds its position pneumatically without a spring. By factory default, energising the AC220V coil retracts the rod, but you can reposition the valve to extend-when-energised. The valve routes air but does not lock the rod; for dead-air load holding, use a SAIL or BSAI cylinder.
