Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X125-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X125-08A is a genuine double-acting profile-type cylinder with a Ø80mm bore, 125mm 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 SAUF80X125-08A
The SAUF80X125-08A is a double-acting profile cylinder with a built-in AirTAC 4M310-08 5/2 solenoid valve on the cap. One AC220V coil signal drives the actuator, eliminating remote plumbing and saving a manifold slot. The extruded aluminum barrel is shorter than an ISO 15552 unit of the same bore. This 80mm bore uses a 3/8" cylinder port, a Ø25mm rod with an M20x1.5 thread, and 28mm adjustable cushions.
Operating strictly within the valve's 0.15-0.8 MPa window, it delivers 2513N push force at 0.5 MPa. The 1/4" valve port flows 25 mm2 (Cv 1.4) at up to 4 cycles per second. For sizing, the safe working load is roughly 1508N, and it can vertically lift about 128kg with a 2:1 margin. This terminal-entry, PT-thread SKU lacks a magnet, so it cannot accept 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 SAUF80X125-08A Is Used
Machine Tool Clamping
Decentralized clamping on a large machining center where the integrated valve provides rapid 4 cycles per second actuation directly at the fixture.
Package Diverting
Independent diverting arms along a material handling line, saving manifold space and tubing by switching each actuator with its own AC220V coil.
Vertical Lift Gates
Lifting small access gates in an automated storage system, utilizing the 2513N push force at 0.5 MPa to move loads safely under 1508N.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X125-08A the Right Choice?
Size this 80mm bore against the neighboring 63mm and 100mm options using the 0.5 MPa figures: 63mm pushes 1559N, 80mm pushes 2513N, and 100mm pushes 3927N. Confirm the AC220V terminal entry and PT thread meet your control spec. The default action retracts the rod when energized, but you can reposition the valve to extend on signal. Always size force within the 0.15-0.8 MPa valve range, never the 1.0 MPa cylinder body rating. Because this SKU lacks a magnet, you cannot mount a magnetic sensor. The integrated valve routes air and is not a lock; for load holding on air loss, add an external rod lock or pilot-operated check valve. For this 125mm stroke side-load is minimal, but if you approach 300mm or more, guide the load to prevent rod bending.
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 SAUF80X125-08A FAQ
It features an 80mm bore, 125mm stroke, and a built-in 4M310-08 valve with a 1/4" port flowing 25 mm2 (Cv 1.4). The AC220V terminal-entry coil runs at up to 4 cycles per second. It pushes 2513N at 0.5 MPa. You must size force within the valve's 0.15-0.8 MPa operating window, not the 1.0 MPa cylinder body rating.
By default the rod retracts when the coil is energized, but you can reconfigure it to extend by repositioning the valve. The valve only routes air; it is not a load lock. The piston will drift on air loss, so add an external rod lock or pilot-operated check valve if you need to hold a load.
