Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X80S-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X80S-08B is a genuine double-acting profile-type cylinder with a Ø100mm bore, 80mm 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 SAUF100X80S-08B
The SAUF100X80S-08B is a double-acting profile 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 extruded aluminum barrel is shorter than an ISO 15552 unit of the same bore. The 80 mm stroke exceeds the 75 mm minimum for this bore, and the piston magnet supports CMSG/DMSG/EMSG switches.
The integrated valve delivers 1/4" porting with a Cv of 1.4 and runs up to 4 cycles per second. The cylinder body rates to 1.0 MPa, but the assembled unit operates within the valve's 0.15-0.8 MPa window, generating 6282 N of push force at 0.8 MPa. For sizing, the push force at 0.5 MPa is 3927 N, yielding a safe working load of roughly 2356 N and a vertical lift capacity of about 200 kg with a 2:1 margin. The 1/2" cylinder port and 29 mm adjustable cushions manage the high flow.

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 (Ø100mm)

|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 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 SAUF100X80S-08B Is Used
Decentralized Press Clamps
Uses the integrated 4M310 valve to clamp heavy steel billets directly at the tooling point without routing long tube runs back to a central manifold.
Independent Pallet Stops
Deploys one coil signal per actuator to halt 200 kg pallets on a conveyor, saving manifold space and simplifying localized flow control.
Modular Assembly Lifts
Lifts subassemblies with a 2356 N safe working load, relying on the built-in magnet and CMSG switches to confirm position at each station.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X80S-08B the Right Choice?
When sizing, compare neighboring bores: the 80 mm bore provides 2513 N push at 0.5 MPa, while this 100 mm bore provides 3927 N. Confirm the DC24V terminal entry and PT threads suit your control panel. The default action retracts the rod when energized, but you can reconfigure it to extend by repositioning the valve. Size force within the 0.15-0.8 MPa valve range, never the 1.0 MPa cylinder body rating. The valve routes air and does not hold the load on pressure loss; add an external rod lock or pilot-operated check valve for suspended loads. Since the 80 mm stroke is under 300 mm, side-load guide requirements are minimal.
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 SAUF100X80S-08B FAQ
It generates 3927 N push and 3681 N pull at 0.5 MPa, reaching 6282 N push at 0.8 MPa. The built-in valve is a 4M310-08 5/2 solenoid with a 1/4" port, Cv 1.4, and a DC24V coil. Although the cylinder body rates to 1.0 MPa, the assembled unit must operate within the valve's 0.15-0.8 MPa window.
No, the built-in valve only routes air and is not a load lock. If air is lost, the piston drifts. The default action retracts the rod when energized, but you can reconfigure it to extend by repositioning the valve. For suspended loads, install an external rod lock or pilot-operated check valve.
