Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X100S-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X100S-08A is a genuine double-acting profile-type 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 SAUF Series Valve-Mounted Air Cylinder SAUF80X100S-08A
The SAUF80X100S-08A is a double-acting profile cylinder with a built-in AirTAC 4M310 5/2 solenoid valve on the cap. One coil signal drives the actuator, eliminating remote plumbing and saving a manifold slot. The extruded aluminum barrel makes it shorter than an ISO 15552 unit of the same bore. It features a 3/8" cylinder port, an M20x1.5 rod thread, and a 28 mm adjustable cushion.
Operating in the 0.15-0.8 MPa valve window, it delivers 2513 N push force at 0.5 MPa. The integrated valve provides 25 mm2 flow (Cv 1.4) at a 1/4" port, cycling up to 4 times per second. The S suffix denotes a piston magnet for CMSG/DMSG/EMSG switches. For sizing, the safe working load is roughly 1508 N, yielding a 128 kg vertical lift capacity with a 2:1 margin.

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 (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 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.

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 SAUF80X100S-08A Is Used
Machine Tool Clamping
Decentralized clamping on a large machining center. The built-in valve provides rapid 4 cycle/sec actuation directly at the clamp without a remote manifold.
Diversion Gates
Routing packages on a high-speed line. One coil signal per gate saves tubing complexity, and the 2513 N push force handles heavy cardboard easily.
Pallet Stopper Arms
Stopping pallets on a roller conveyor. The compact profile fits tight transfer zones, while the 128 kg vertical lift capacity secures loads reliably.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X100S-08A the Right Choice?
When sizing, compare neighbouring bores: a 63 mm bore yields 1559 N push at 0.5 MPa, while a 100 mm bore yields 3927 N. This 80 mm bore provides 2513 N, fitting cleanly between them. Confirm the AC220V terminal entry and PT thread match your supply. The rod retracts when the coil is energised, but you can reposition the valve to extend on signal. Always size force within the 0.15-0.8 MPa valve range, not the 1.0 MPa cylinder body rating. The valve routes air and is not a load lock; add an external rod lock or pilot-operated check valve to hold a load. For this 100 mm stroke, side-load is minimal, but always guide the rod for longer travels.
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 SAUF80X100S-08A FAQ
It delivers 2513 N push and 2268 N pull at 0.5 MPa, reaching 4021 N push at 0.8 MPa. The built-in valve is a 4M310-08 (1/4" port, Cv 1.4, 25 mm2 flow) running on AC220V. You must size force within the valve's 0.15-0.8 MPa operating window, even though the cylinder body rates to 1.0 MPa.
By default, the rod retracts when the coil is energised, but you can reposition the valve to extend on signal. The 5/2 valve routes air; it is not a load lock. If air is lost, the piston drifts, so add an external rod lock or pilot-operated check valve for suspended loads.
