Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X150S-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X150S-08A is a genuine double-acting profile-type cylinder with a Ø100mm bore, 150mm 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 SAUF Series Valve-Mounted Air Cylinder SAUF100X150S-08A
The SAUF100X150S-08A is a double-acting profile cylinder with a built-in AirTAC 4M310 5/2 solenoid valve. One coil signal drives the actuator, eliminating remote plumbing and saving a manifold slot. The extruded aluminum barrel is shorter than an ISO 15552 cylinder of the same bore. The S suffix provides a piston magnet for CMSG/DMSG/EMSG switches.
The 100mm bore delivers 3927N push and 3681N pull at 0.5MPa. The integrated 4M310-08 valve has a 1/4" port, Cv 1.4, and handles 4 cycles/sec. The cylinder body rates to 1.0MPa, but the valve limits operation to 0.15-0.8MPa. Based on the 0.5MPa push force, the safe working load is 2356N, yielding a 200kg vertical lift capacity with a 2:1 margin. The bore sets the 1/2" cylinder port, while the coil uses AC220V terminal entry.

The cylinder rates to 1.0 MPa but the built-in valve operates 0.15–0.8 MPa, so run the assembled SAUF at 0.15–0.8 MPa. Default: rod retracts when the coil is energised (reconfigurable to extend). Specs follow the official AirTAC SAUF 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.

SAUF does not hold its load without air — the valve routes air, it is not a lock. For a held load, add an external rod lock or a pilot-operated check valve.
Where the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X150S-08A Is Used
Machine Tool Clamping
Decentralized clamping on a large CNC machining center. The built-in valve provides rapid local actuation without routing long tube runs back to a central manifold.
Heavy Divert Gate
Powering a heavy diverter gate on a packaging line. The 100mm bore provides high push force, and the integrated valve ensures fast response times for high-throughput sorting.
Pallet Stopper Arm
Actuating a heavy-duty stopper arm on a pallet conveyor. One coil signal controls the stop motion directly at the station, saving manifold space and simplifying wiring.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X150S-08A the Right Choice?
Size by comparing the 100mm bore (3927N push @0.5MPa) against the 80mm neighbor (2513N push). The 150mm stroke is standard and above the 75mm SAUF minimum. Confirm the AC220V terminal entry and PT threads match your supply. The rod retracts when energized by default; reposition the valve to extend on signal. Always size force within the 0.15-0.8MPa valve window, never the 1.0MPa cylinder rating. The valve routes air and is not a lock; add an external rod lock or pilot-operated check valve to hold loads. For strokes over 300mm, use SC-series mounting accessories and guide the load to prevent side-load wear.
Quick checklist
- ✓ Force at 0.15–0.8 MPa
- ✓ Coil voltage matches panel
- ✓ Terminal vs grommet entry
- ✓ Retract- or extend-when-energised
- ✓ Load-holding → external rod lock
Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X150S-08A FAQ
It delivers 3927N push and 3681N pull at 0.5MPa. The built-in valve is a 4M310-08 (1/4" port, Cv 1.4, max 4 cycles/sec) with an AC220V terminal entry coil. Although the cylinder body rates to 1.0MPa, the assembled unit operates strictly within the 0.15-0.8MPa valve window.
Yes. By default, the rod retracts when the coil is energized. You can reconfigure it to extend on signal by physically repositioning the built-in valve on the cap. This allows you to choose the fail-safe state for your application without extra remote valves.
