Airtac SAIF Series Standard Cylinder with Valve SAIF100X800S-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF100X800S-08A is a genuine double-acting ISO 15552 cylinder with a Ø100mm bore, 800mm 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 SAIF100X800S-08A
The AirTAC SAIF100X800S-08A is a double-acting ISO 15552 profile cylinder featuring an integrated 4M310-08 5/2 solenoid valve. This built-in valve delivers a Cv of 1.40 and operates at 0.15-0.8 MPa, which sets the practical working pressure for the assembly despite the cylinder body rating of 1.0 MPa. Driven by an AC220V terminal entry coil consuming 3.5 VA, it responds in 0.05s and carries an IP65 rating. The -S magnet enables position sensing with CMSE reed and DMSE electronic switches.
Providing 5497N of push force at 0.7 MPa, this self-contained unit eliminates remote valve plumbing. The manifold connects the 1/4 valve port to the 1/2 cylinder port via O10xO6.5 PU tubing. Factory set to retract the rod when the coil is energised, the valve can be repositioned to extend on signal. The carbon steel rod and extruded aluminum barrel ensure robust performance for decentralized machine stations.

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 SAIF100X800S-08A Is Used
Decentralized Automation
Ideal for large machines with multiple stations, eliminating long air lines from a central manifold by switching directly at the cylinder.
High Force Handling
Delivers 5497N push force at 0.7 MPa, suitable for heavy lifting and pressing tasks within a compact ISO 15552 profile envelope.
Wiring Simplification
Requires only a single AC220V electrical signal to operate, drastically reducing panel wiring and valve island complexity.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF100X800S-08A the Right Choice?
Choose this 100mm bore when 80mm falls short, as the 80mm variant only yields 3518N push at 0.7 MPa. The 800mm stroke requires external guide support to manage side loads and prevent rod binding. Because the 4M310-08 valve is directly mounted, this SAIF model is ideal for decentralized stations where running individual valve tubing from a central panel is costly or space-prohibitive.
This assembly uses a PT tapered thread port and an AC220V terminal coil. Remember that the 5/2 valve routes air and is not a lock; it will not hold a load without live pressure. For position holding, consider the SAIL lock series. To replace this unit, match the 100mm bore, 800mm stroke, 1/4 valve port, AC220V terminal coil, 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 SAIF100X800S-08A FAQ
The 100mm bore cylinder provides 5497N push force at 0.7 MPa. The integrated 4M310-08 5/2 valve has an effective area of 25.0 mm2 (Cv 1.40) and a max frequency of 4 cycles per second.
No, the 5/2 valve routes air but does not lock the load; it will not hold position without live pressure. Also, the factory setting retracts the rod when energised, but it can be reconfigured to extend on signal by repositioning the valve.
