Airtac SAIF Series Standard Cylinder with Valve SAIF100X80S-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF100X80S-08A is a genuine double-acting ISO 15552 cylinder with a Ø100mm bore, 80mm 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 SAIF100X80S-08A
The AirTAC SAIF100X80S-08S is a double-acting ISO 15552 profile cylinder equipped with a built-in 4M310-08 5/2 solenoid valve, delivering a Cv of 1.40 and a 25.0 mm2 effective area. Driven by an AC220V terminal coil consuming 3.5 VA, it activates in 0.05 s with an IP65 rating. Because the cylinder body rates to 1.0 MPa but the internal pilot valve operates at 0.15-0.8 MPa, the practical working range for this assembled unit is 0.15-0.8 MPa. It delivers substantial thrust, generating 3927 N of push force at 0.5 MPa and peaking at 801 kgf at 1.0 MPa.
This decentralized design eliminates the need for a separate remote valve, reducing panel space and plumbing. The manifold connects to the cylinder via PU tubing (O10 x O6.5), and the valve port (1/4) is intentionally smaller than the cylinder port (1/2) to optimize flow control. 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 included -S magnet works seamlessly with AirTAC CMSE reed and DMSE electronic sensors for precise position feedback.

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 (Ø100mm)

| 0.7 MPa | 5498 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 SAIF100X80S-08A Is Used
Decentralized Automation
Perfect for large-scale production lines needing localized control. The integrated 4M310-08 valve eliminates long pneumatic runs back to a central manifold.
High-Force Clamping
Delivers up to 801 kgf at 1.0 MPa for securing heavy workpieces during machining, utilizing its 100mm bore and 5/2 valve for rapid actuation.
Retrofit & Upgrade
Ideal for upgrading existing ISO 15552 setups where panel space is tight, adding self-switching logic without the need for external valve islands.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF100X80S-08A the Right Choice?
Choose this 100mm bore when your application requires high force, as it delivers 3927 N of push force at 0.5 MPa. If your system operates at lower pressures or needs less push, stepping down to an 80mm bore yields 2513 N at 0.5 MPa, while moving up is not available as 100mm is the largest SAIF size. The SAIF100X80S-08A is ideal for decentralized stations across large machines where running separate valve tubing is costly, as it switches itself from a single AC220V terminal coil signal.
When replacing or specifying, match the 100mm bore, 80mm stroke, 1/4 valve port, AC220V voltage, PT tapered thread, terminal entry, and the -S magnet. Remember that the built-in 5/2 valve routes air but does not lock the load; if you need true position holding without live pressure, consider the AirTAC SAIL lock cylinder or BSAI clamp-lock series 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 SAIF100X80S-08A FAQ
At 0.5 MPa operating pressure, this 100mm bore cylinder provides 3927 N of push force and 3681 N of pull force. At the maximum practical valved pressure of 0.8 MPa, it generates 5497 N of push force.
Yes. The factory default setting retracts the piston rod when the AC220V coil is energised. By physically repositioning the built-in 4M310-08 5/2 valve, you can reconfigure it to extend-when-energised. No separate remote valve is needed.
