Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X175S-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X175S-08B is a genuine double-acting profile-type cylinder with a Ø80mm bore, 175mm 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 SAUF80X175S-08B
The SAUF80X175S-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 80mm bore delivers 2513N push and 2268N pull at 0.5MPa, with a 3/8" cylinder port and M20x1.5 rod thread.
The integrated 4M310-08 valve has a 1/4" port, Cv 1.4 flow, and cycles up to 4 times per second. The DC24V coil offers IP65 protection with terminal entry. Size force within the 0.15-0.8MPa valve window, not the 1.0MPa cylinder body rating. Based on the 0.5MPa push force, the safe working load is roughly 1508N, yielding a vertical lift capacity of about 128kg with a 2:1 margin. The S suffix means a piston magnet is included 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 SAUF80X175S-08B Is Used
Diverter Gate Actuation
Drives a decentralized lane diverter directly at the conveyor, using the built-in valve to switch instantly without routing air lines back to a central manifold.
Pallet Stopper Control
Raises and lowers a heavy pallet stop in a packaging line, leveraging the 2513N push force and integrated 4M310 valve for compact, localized control.
Clamp Station Operation
Actuates a machining clamping fixture with a single DC24V signal, saving manifold space while providing reliable 0.15-0.8MPa clamping pressure.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X175S-08B the Right Choice?
Size by comparing neighbour bores: the 63mm bore gives 1559N push at 0.5MPa, while this 80mm bore gives 2513N, and the 100mm bore gives 3927N. Confirm the DC24V coil and terminal entry match your control system. The rod retracts by default when energised, but you can reconfigure it to extend by repositioning the valve. Always size within the 0.15-0.8MPa valve operating range. Because the built-in valve only routes air, add an external rod lock or pilot-operated check valve to hold loads safely. For this 175mm stroke, ensure adequate side-load guidance using SC-series accessories.
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 SAUF80X175S-08B FAQ
It delivers 2513N push and 2268N pull at 0.5MPa, reaching 4021N push at 0.8MPa. The built-in valve is a 4M310-08 (1/4" port, Cv 1.4, max 4 cycles/sec) driven by a DC24V terminal-entry coil. Although the cylinder body rates to 1.0MPa, the assembled unit must operate within the 0.15-0.8MPa valve window.
The default action retracts the rod when the coil is energised. You can reconfigure it to extend-when-energised simply by repositioning the built-in valve. Because the valve only routes air, it is not a load lock; use an external rod lock or pilot-operated check valve if you need to hold a load.
