Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X100S-06B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X100S-06B is a genuine double-acting profile-type cylinder with a Ø40mm bore, 100mm stroke and a built-in 4M210-06 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-06B
The SAUF40X100S-06B is a double-acting profile cylinder with a built-in AirTAC 4M210-06 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. This 40mm bore uses a 1/4" cylinder port, a Ø16mm rod with an M12x1.25 thread, and 21mm adjustable cushions.
Operating on DC24V with terminal entry, the integrated valve provides 1/8" porting, 14.0 mm2 flow (Cv 0.78), and up to 5 cycles/sec. The cylinder body rates to 1.0 MPa, but you must size force within the valve's 0.15-0.8 MPa window. At 0.5 MPa it pushes 628 N and pulls 528 N. The computed safe working load is about 377 N (60% of the 0.5 MPa push), offering a vertical lift capacity of roughly 32 kg with a 2:1 margin. The S suffix means a piston magnet is present 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 SAUF40X100S-06B Is Used
Decentralized Clamping
Ideal for a machining cell where each clamping station uses one coil signal to actuate independently, saving manifold space and routing complex tubing.
Inline Divert Gate
Perfect for a conveyor divert gate that needs a self-contained actuator; the built-in 4M210 valve handles 5 cycles/sec without a remote valve bank.
Package Stopper Arm
Suits packaging lines where a localized stopper arm must deploy quickly; the DC24V terminal coil and integrated valve simplify electrical and air hookup.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X100S-06B the Right Choice?
When sizing, compare neighbouring bores: a 32mm bore yields 402 N push at 0.5 MPa, while a 50mm bore provides 982 N. This 40mm bore gives 628 N push and 528 N pull at 0.5 MPa. Confirm your coil is DC24V with terminal entry before ordering. The default action retracts the rod when energised, but you can reconfigure it to extend-when-energised by repositioning the valve. Always operate within the 0.15-0.8 MPa valve range, never the 1.0 MPa cylinder body limit. Because the valve only routes air, add an external rod lock or pilot-operated check valve to hold loads securely. For this 100mm stroke, side-load is minimal, but for strokes >=300mm use a guide to prevent rod binding.
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-06B FAQ
It generates 628 N push and 528 N pull at 0.5 MPa. The built-in valve is a 4M210-06 (1/8" port, Cv 0.78, 5/2 solenoid) running on a DC24V terminal-entry coil. Although the cylinder body rates to 1.0 MPa, the assembled unit must operate within the 0.15-0.8 MPa valve window.
No, the built-in valve only routes air and is not a load lock; the piston will drift on air loss. Also, the default action retracts the rod when energised, but you can switch it to extend-when-energised by repositioning the valve. For secure load holding, install an external rod lock or pilot-operated check valve.
