Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X100S-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X100S-08B is a genuine double-acting profile-type cylinder with a Ø40mm bore, 100mm 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 SAUF40X100S-08B
The SAUF40X100S-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 cylinder of the same bore. It features a piston magnet for CMSG/DMSG/EMSG switches.
The 40mm bore delivers 628N push and 528N pull at 0.5MPa. The integrated valve has a 1/4" port, 16mm2 flow (Cv 0.89), and handles 5 cycles/sec. The cylinder body rates to 1.0MPa, but the valve limits operation to 0.15-0.8MPa. For sizing, the safe working load is roughly 377N (60% of the 0.5MPa push force), allowing a vertical lift of about 32kg with a 2:1 margin.

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 SAUF40X100S-08B Is Used
Decentralized Clamping
Ideal for a machining cell where each clamping station uses its own SAUF cylinder, removing the need for a central valve manifold and long tubing runs.
Inline Diverters
Perfect for conveyor diverters requiring a single coil signal per actuator, simplifying wiring and maximizing available cabinet space.
Independent Lift Gates
Suited for independent lift gates in material handling, offering localized 5/2 valve control without complex remote plumbing.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X100S-08B the Right Choice?
Size against the 32mm and 50mm bores: this 40mm bore gives 628N push at 0.5MPa, sitting between the 32mm (402N) and 50mm (982N) options. Confirm the DC24V coil and terminal entry suit your control system. The rod retracts by default when energised; you can reposition the valve to extend on energisation. Always size force within the 0.15-0.8MPa valve window, never the 1.0MPa cylinder body rating. The valve only routes air, so add an external rod lock or pilot-operated check valve to hold loads safely. For this 100mm stroke, side-load guides are not strictly required but ensure standard SC-series mounting accessories are used.
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 SAUF40X100S-08B 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 a DC24V coil. Although the cylinder body rates to 1.0MPa, the assembled unit operates strictly within the 0.15-0.8MPa valve window.
Yes. The default action retracts the rod upon energisation, but you can reconfigure it to extend-when-energised simply by repositioning the built-in valve. This allows flexible machine sequencing without extra hardware.
