Airtac SAIF Series Standard Cylinder with Valve SAIF80X100S-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF80X100S-08B 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-08B
The AirTAC SAIF80X100S-08B is a double-acting ISO 15552 profile cylinder equipped with a built-in 4M310-08 5/2 solenoid valve. Driven by a DC24V terminal coil consuming 3.0W, it delivers 2513N of push force at 0.5MPa. Because the manifold routes air via PU tubing (O10xO6.5) directly to the cylinder ports, you get true decentralized control from a single electrical signal without remote valve islands. The integrated valve operates at 0.15-0.8MPa, which defines the practical working range for this assembled unit despite the bare cylinder rating of 1.0MPa.
This specific SKU includes a magnet for position sensing with CMSE reed or DMSE electronic switches. By factory default, the piston rod retracts when the coil is energised, but you can reconfigure it to extend-when-energised simply by repositioning the valve. The assembly uses PT tapered threads for both the valve and cylinder ports, and the 5/2 valve holds its position pneumatically via internal pilot, meaning it is not a lock or brake for holding loads without live pressure.

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 SAIF80X100S-08B Is Used
Decentralized Automation
Perfect for large machine grids requiring localized actuation, eliminating long tubing runs back to a central valve island.
High-Force Clamping
Delivers 2513N of push force at 0.5MPa, suitable for heavy-duty workholding and industrial clamping tasks.
Retrofit Upgrades
Ideal for upgrading existing ISO 15552 cylinders to self-switching units where adding standalone valves is mechanically difficult.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF80X100S-08B the Right Choice?
Choose this 80mm bore when your application requires substantial thrust—stepping down to the 63mm bore drops your push force to 1559N at 0.5MPa, while stepping up to 100mm yields 3927N. A self-valved SAIF cylinder is ideal for space-tight machines or retrofits where running pneumatic tubing back to a central panel is costly, as it eliminates separate remote valves and slashes plumbing complexity.
When ordering a replacement, verify the 100mm stroke, 1/4" valve port, DC24V terminal electrical entry, PT thread, and the -S magnet. For any stroke exceeding 300mm, add external guide rails to prevent side-load damage, though this 100mm stroke is well within safe limits. If your process requires true load holding under pressure loss, look to the SAIL lock or BSAI clamp-lock series instead, as the SAIF 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 SAIF80X100S-08B FAQ
At 0.5MPa, the 80mm bore generates 2513N of push force and 2268N of pull force. The built-in 4M310-08 5/2 valve has an effective orifice of 25.0mm2 (Cv 1.40) and a maximum frequency of 4 cycles per second.
No, the 5/2 valve routes air but does not lock the load; it holds position pneumatically, so live pressure is required. The DC24V coil draws 3.0W, and by factory default, energising the coil retracts the rod, though this can be reconfigured to extend-when-energised by repositioning the valve.
