Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X150S-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X150S-08B is a genuine double-acting profile-type cylinder with a Ø80mm bore, 150mm 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 SAUF80X150S-08B
The SAUF80X150S-08B is a double-acting profile cylinder with a built-in AirTAC 4M310-08 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 is shorter than an ISO 15552 unit of the same bore. This 80mm bore delivers 2513N push and 2268N pull at 0.5MPa, with a 3/8" cylinder port and an M20x1.5 rod thread.
The integrated valve offers 1/4" porting, 25mm2 flow (Cv 1.4), and runs up to 4 cycles/sec. The DC24V coil is IP65 rated with a 0.05s response. 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 about 1508N, allowing a vertical lift of roughly 128kg with a 2:1 margin. The S suffix denotes 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 SAUF80X150S-08B Is Used
Package Diverting
Decentralized sorting gates where one coil signal per actuator removes the need for a central valve manifold and long tube runs.
Vertical Lifting
Elevating 128kg loads in storage systems using the 80mm bore, relying on the built-in 4M310-08 valve for fast 4 cycle/sec actuation.
Machine Clamping
Independent workpiece clamping on large machines, saving installation time by integrating the 5/2 valve directly on the cylinder cap.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X150S-08B the Right Choice?
When sizing, compare neighbouring bores: the 63mm bore yields 1559N push at 0.5MPa, while the 100mm bore reaches 3927N. This 80mm unit provides 2513N push, making it ideal for mid-range loads. Confirm the DC24V 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 signal. Always operate within the 0.15-0.8MPa valve pressure range. The built-in 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 150mm stroke, ensure side-load guidance 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 SAUF80X150S-08B FAQ
It delivers 2513N push and 2268N pull at 0.5MPa. The built-in valve is a 4M310-08 with a 1/4" port and Cv 1.4. The DC24V coil operates at 0.15-0.8MPa; do not exceed 0.8MPa despite the 1.0MPa cylinder body rating.
By default, the rod retracts when the coil is energised. You can reconfigure it to extend-when-energised simply by repositioning the built-in valve. This self-switching design removes the need for a separate remote valve.
