Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X125-10B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X125-10B is a genuine double-acting profile-type cylinder with a Ø80mm bore, 125mm stroke and a built-in 4M310-10 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 SAUF80X125-10B
The SAUF80X125-10B is an extruded aluminum profile-type double-acting cylinder with a built-in AirTAC 4M310 5/2 solenoid valve on the cap. One DC24V coil signal drives the actuator, eliminating remote plumbing and saving a manifold slot. The bore is 80mm, stroke 125mm, and the cylinder air port is 3/8". It is shorter than an ISO 15552 cylinder of the same bore.
Size force within the 0.15-0.8 MPa valve window, even though the cylinder body rates to 1.0 MPa. At 0.5 MPa it pushes 2513 N and pulls 2268 N. The safe working load is roughly 1508 N, allowing a vertical lift of about 128 kg with a 2:1 margin. The 3/8" valve port yields a Cv of 1.68 and a 4 cycles/s max frequency. This terminal-entry, PT-thread SKU lacks a magnet, so it cannot take a magnetic switch.

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 SAUF80X125-10B Is Used
Machine Tool Clamping
Decentralized clamping on a large machining center. The built-in 4M310 valve provides rapid local actuation without routing long tube runs back to a central manifold.
Heavy Divert Gate
Actuating a heavy divert gate on a packaging line. The 80mm bore provides 2513 N push at 0.5 MPa, and the single coil signal simplifies control wiring.
Pallet Stopper Arm
Stopping pallets on a roller conveyor. The integrated valve handles 4 cycles/s, and the compact profile fits tight transfer station footprints.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X125-10B the Right Choice?
Compare both ways: a 63mm bore offers 1559 N push at 0.5 MPa, while a 100mm bore yields 3927 N. This 80mm bore delivers 2513 N push and 2268 N pull at 0.5 MPa. Confirm the DC24V terminal entry and PT threads. The default action retracts the rod when energised; reposition the valve to extend on signal. Limit pressure to the valve's 0.15-0.8 MPa range. The valve routes air and is not a lock; add an external rod lock or pilot-operated check valve to hold a load. For this 125mm 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 SAUF80X125-10B FAQ
It pushes 2513 N and pulls 2268 N at 0.5 MPa. The built-in valve is a 4M310-10 (3/8" port, Cv 1.68, max 4 cycles/s) with a DC24V terminal-entry coil. Although the cylinder body rates to 1.0 MPa, the assembled unit operates at 0.15-0.8 MPa.
No. The built-in 5/2 valve routes air but is not a load lock. The rod drifts on air loss, and the 28mm cushions only decelerate near stroke end. Add an external rod lock or pilot-operated check valve for load holding.
