Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X75S-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X75S-08A is a genuine double-acting profile-type cylinder with a Ø80mm bore, 75mm 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 SAUF80X75S-08A
The SAUF80X75S-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. The 80mm bore uses a 3/8" cylinder port, a 25mm rod, and M20x1.5 rod-end thread.
Operating within the 0.15-0.8 MPa valve window, it delivers 2513 N push force at 0.5 MPa. A computed buyer insight: safe working load is roughly 1508 N, with a vertical lift capacity of about 128 kg at a 2:1 margin. The integrated 4M310-08 valve features a 1/4" port, Cv 1.4, and cycles up to 4 times per second. The AC220V terminal-entry coil is IP65 rated. The S suffix provides a piston magnet for CMSG/DMSG/EMSG switches.

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 SAUF80X75S-08A Is Used
Decentralized Conveyor Diverter
Mounts directly at the divert station to push packages, switching itself with one AC220V signal and cutting tubing runs back to a central manifold.
Independent Machine Clamp
Provides standalone clamping on a large assembly line, using the integrated 4M310 valve to actuate instantly without consuming manifold slots.
Vertical Lift Gate
Lifts light gates using the 128kg vertical lift capacity, relying on the built-in magnet for position feedback and the compact profile to save space.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X75S-08A the Right Choice?
Size by comparing neighbour bores: the 63mm bore yields 1559 N push at 0.5 MPa, while the 100mm bore yields 3927 N. This 80mm bore provides 2513 N push and 2268 N pull at 0.5 MPa. Confirm the AC220V terminal entry and PT threads suit your control panel. The default action retracts the rod when energised, but you can reposition the valve to extend on energisation. Always size force 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 load lock; add an external rod lock or pilot-operated check valve to hold loads safely. For strokes of 300mm or longer, use side-load guides to prevent rod damage.
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 SAUF80X75S-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, max 4 cycles/sec). The cylinder body rates to 1.0 MPa, but you must size force within the valve's 0.15-0.8 MPa operating window. The coil is AC220V 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, and 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.
