Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X160S-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X160S-08A 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-08A
The SAUF40X160S-08A is an extruded aluminum profile-type double-acting 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 40mm bore delivers 628N push and 528N pull at 0.5MPa, operating safely inside the valve's 0.15-0.8MPa window.
The integrated valve offers 1/4" porting, 16mm2 flow (Cv 0.89), and 5 cycles/sec. This AC220V terminal-entry coil is IP65 rated. A computed buyer insight: safe working load is roughly 377N (60% of the 0.5MPa push), enabling a 32kg vertical lift 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 (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-08A Is Used
Decentralized Clamping Stations
Distributes clamping across a large fixture using one AC220V signal per actuator, removing the need for a central manifold.
Independent Gating Modules
Controls separate diverters on a conveyor line, cutting tubing runs and simplifying maintenance access.
Compact Assembly Cells
Fits 40mm profile cylinders into tight machine cells where shorter-than-standard bodies and integrated switching excel.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X160S-08A the Right Choice?
Size against the 40mm bore's 628N push at 0.5MPa; step up to 50mm (982N) for heavier loads or down to 32mm (402N) for lighter duties. Confirm the AC220V terminal entry suits your control panel. Default action retracts the rod when energised, but repositioning the valve flips this to extend-when-energised. Always size force within the 0.15-0.8MPa valve range, not the 1.0MPa cylinder body rating. The built-in valve routes air and is not a lock; add an external rod lock or pilot-operated check valve to hold loads safely. For this 160mm stroke, ensure external guidance to manage side loads.
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-08A FAQ
It delivers 628N push and 528N pull at 0.5MPa. The built-in valve is a 4M210-08 (1/4" port, Cv 0.89, 5 cycles/sec) with an AC220V terminal-entry coil. The cylinder body rates to 1.0MPa, but you must size force within the valve's 0.15-0.8MPa operating window.
Yes. The default action retracts the rod when the coil is energised, but you can reconfigure it to extend-when-energised simply by repositioning the valve. This self-switching design means no remote valve is required, saving installation time.
