Airtac SAIF Series Standard Cylinder with Valve SAIF100X900S-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF100X900S-08A is a genuine double-acting ISO 15552 cylinder with a Ø100mm bore, 900mm 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 SAIF100X900S-08A
The AirTAC SAIF100X900S-08A 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 a 25.0 mm2 effective area. Driven by an AC220V terminal coil drawing 3.5 VA, it integrates switching directly on the actuator. The cylinder body rates to 1.0 MPa, but because 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 robust thrust, pushing with 3927N and pulling with 3681N at 0.5 MPa.
By generating motion from a single coil signal, it eliminates remote plumbing and saves panel space, making it perfect for decentralized stations. The factory setting retracts the rod when the coil is energised, but you can reposition the valve to extend-when-energised. The manifold links the valve to the cylinder via O10 x O6.5 PU tubing, and the PT1/4 valve port is distinct from the cylinder's PT1/2 port. Fitted with a magnet, it supports 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)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 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 SAIF100X900S-08A Is Used
Decentralized Automation Stations
Ideal for large-scale facilities where running individual valve lines is costly, letting each 100mm bore actuator switch itself locally from a single AC220V signal.
Heavy Pressing Operations
Provides substantial 3927N push force at 0.5 MPa for clamping and pressing heavy assemblies without needing a separate valve manifold.
Retrofitted Machinery
Drops into existing ISO 15552 footprint setups to add self-switching capability, cutting down on pneumatic plumbing and panel space.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF100X900S-08A the Right Choice?
Choose this 100mm bore when you need maximum push force (3927N at 0.5 MPa); stepping down to an 80mm bore drops that to 2513N. The self-valved design beats a separate cylinder and remote valve when you need to minimize wiring and tubing across a large machine. Since the stroke is 900mm, adding an external guide is recommended to manage side loads and prevent rod deflection. Remember that the 5/2 valve routes air but does not lock the load—use a SAIL lock or BSAI clamp-lock for position holding. To replace this unit, match the 100mm bore, 900mm stroke, PT1/4 valve port, AC220V terminal coil, PT thread, and the -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 SAIF100X900S-08A FAQ
The cylinder delivers 3927N of push force and 3681N of pull force at 0.5 MPa. The built-in 4M310-08 5/2 valve has an effective area of 25.0 mm2 (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; for holding, use a SAIL or BSAI clamp. This model uses an AC220V terminal coil (3.5 VA, IP65). The factory setting retracts the rod when energised, but you can reposition the valve to extend-when-energised.
