Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X100S-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X100S-08B 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-08B
The SAUF80X100S-08B 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 cylinder of the same bore. The 80mm bore has a 3/8" cylinder port, a 25mm rod, and adjustable 28mm cushions.
Operating within the 0.15-0.8 MPa valve window, it delivers 2513 N push at 0.5 MPa. A computed buyer insight: safe working load is roughly 1508 N, and it can vertically lift about 128 kg with a 2:1 margin. The integrated valve provides 25 mm2 flow (Cv 1.4) at a 1/4" port, switching up to 4 cycles per second. It uses a DC24V terminal coil rated IP65, and the S suffix provides a piston magnet for sensors.

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-08B Is Used
Decentralized Press Clamps
Uses one coil signal per clamp station to eliminate valve manifolds, providing 2513 N clamping force at 0.5 MPa directly at the workpoint.
Inline Diverter Gates
Self-switching actuation saves tubing on long conveyors. The 4M310 valve handles 4 cycles per second for rapid package sorting.
Independent Lift Stations
Vertical lift up to 128 kg with a 2:1 margin. The built-in magnet supports electronic sensors for precise height positioning.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X100S-08B the Right Choice?
When sizing, compare the 80mm bore (2513 N push at 0.5 MPa) against the 63mm bore (1559 N) or 100mm bore (3927 N) to match your load. The safe working load is approximately 1508 N. Confirm the DC24V terminal coil and PT thread meet your electrical specs. The default action retracts the rod when energised, but you can reposition the valve to extend on energisation. Size force strictly within the 0.15-0.8 MPa valve range, not the 1.0 MPa cylinder body rating. The built-in valve routes air and is not a lock; add an external rod lock or pilot-operated check valve to hold loads. For this 100mm stroke side-load is minimal, but for strokes over 300mm add a guide.
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-08B FAQ
It delivers 2513 N push at 0.5 MPa and 4021 N at 0.8 MPa. The built-in valve is a 4M310-08 (1/4" port, Cv 1.4). The cylinder body rates to 1.0 MPa, but you must size force within the 0.15-0.8 MPa valve operating window. The coil is DC24V with terminal entry.
No, the built-in 5/2 valve routes air but does not lock the piston. The rod retracts by default when energised, but you can reposition the valve to extend on energisation. For load holding on air loss, install an external rod lock or pilot-operated check valve.
