Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X160S-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X160S-08A is a genuine double-acting profile-type cylinder with a Ø100mm bore, 160mm 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 SAUF100X160S-08A
The SAUF100X160S-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 100mm bore pushes 3927N and pulls 3681N at 0.5MPa. It uses a 1/2" cylinder port and an M20x1.5 rod thread.
The integrated valve has a 1/4" port, Cv 1.4 flow, and cycles up to 4 times per second. Although the cylinder body rates to 1.0MPa, the assembled unit operates strictly within the 0.15-0.8MPa valve window. Based on the 0.5MPa push force, the safe working load is about 2356N, yielding a 200kg vertical lift capacity with a 2:1 margin. The AC220V terminal coil is IP65 rated, and 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 (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 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 SAUF100X160S-08A Is Used
Heavy Duty Clamping
Decentralized clamping on large machining fixtures where running a 100mm bore actuator from a central manifold would waste tubing and space.
Pallet Diverter
A single-signal diverter gate on a high-throughput conveyor, leveraging the 4M310 valve to switch the actuator directly at the point of operation.
Package Sorter
Independent push-off arms in sorting hubs, where each cylinder switches itself to simplify installation across a wide physical footprint.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X160S-08A the Right Choice?
Size by checking neighboring bores: the 80mm bore offers 2513N push at 0.5MPa, while the 100mm bore provides 3927N. Confirm the AC220V terminal entry and PT thread meet your control specs. The default action retracts the rod when energized, but you can reconfigure it to extend by repositioning the valve. Always size force within the 0.15-0.8MPa valve range, never the 1.0MPa cylinder body limit. Because the valve only routes air, add an external rod lock or pilot-operated check valve to hold loads safely. For this 160mm stroke, side-load is minimal, but ensure adequate guidance for longer travels.
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 SAUF100X160S-08A FAQ
It pushes 3927N and pulls 3681N at 0.5MPa, reaching 6282N at 0.8MPa. The built-in valve is a 4M310-08 (1/4" port, Cv 1.4, 4 cycles/s max) driven by an AC220V terminal coil. The cylinder body rates to 1.0MPa, but you must size force within the assembled valve's 0.15-0.8MPa operating window.
No, the built-in 5/2 valve only routes air and is not a lock. The default action retracts the rod when energized, but you can reconfigure it to extend by repositioning the valve. For load holding on air loss, install an external rod lock or pilot-operated check valve.
