Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X160S-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X160S-08B is a genuine double-acting profile-type cylinder with a Ø40mm bore, 160mm stroke and a built-in 4M210-08 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 SAUF40X160S-08B
The SAUF40X160S-08B is a double-acting profile cylinder with a built-in AirTAC 4M210-08 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 makes it shorter than an ISO 15552 unit of the same bore. The S suffix denotes a piston magnet for CMSG/DMSG/EMSG switches.
It delivers 628 N push and 528 N pull at 0.5 MPa. A safe working load is roughly 377 N, with a vertical lift capacity around 32 kg at a 2:1 margin. The integrated valve has a 1/4 inch port, 16 mm2 flow (Cv 0.89), and handles 5 cycles per second. 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 bore uses a 1/4 inch cylinder port and Ø8xØ5 PU tube.

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 (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 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 SAUF40X160S-08B Is Used
Decentralized Clamping
Ideal for a machining cell where the built-in valve allows a single DC24V signal to actuate a clamping jaw directly at the fixture without a remote manifold.
Inline Diverting
Perfect for a conveyor diverter arm; the 4M210-08 valve provides 5 cycles per second for rapid part routing while saving tubing along the frame.
Compact Package Stops
Suits a packaging line stopper gate where the profile barrel saves space and the integrated magnet allows position confirmation via CMSG switches.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X160S-08B the Right Choice?
When sizing, compare neighbouring bores: a 32 mm bore gives 402 N push at 0.5 MPa, while a 50 mm bore yields 982 N. This 40 mm bore provides 628 N push, making the 377 N safe working load ideal for medium-duty decentralised tasks. Confirm the DC24V terminal entry and PT threads meet your specs. The default action retracts the rod when energised, but you can reposition the valve to extend on signal. Always operate within the 0.15-0.8 MPa valve range, never the 1.0 MPa cylinder body rating. The integrated valve routes air and is not a load lock; add an external rod lock or pilot-operated check valve to hold loads safely. For this 160 mm stroke, side-load is minimal, but ensure adequate guidance for longer strokes.
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 SAUF40X160S-08B FAQ
It delivers 628 N push and 528 N pull at 0.5 MPa, with a 1.0 MPa body rating but a 0.15-0.8 MPa operating limit set by the built-in 4M210-08 valve. The valve has a 1/4 inch port, Cv 0.89, and runs on a DC24V terminal entry coil. The cylinder uses a 1/4 inch cylinder port.
Yes. The default factory setting retracts the rod when the coil receives a signal. You can reconfigure it to extend-when-energised simply by repositioning the built-in valve on the cap. Note that the valve only routes air; it does not lock the load, so you need an external rod lock for holding.
