Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X300-10B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X300-10B is a genuine double-acting profile-type cylinder with a Ø100mm bore, 300mm stroke and a built-in 4M310-10 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 SAUF100X300-10B
The SAUF100X300-10B 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 extruded aluminum barrel is shorter than an ISO 15552 cylinder of the same bore. This 100mm bore uses a 1/2" cylinder port, a Ø25mm rod with M20x1.5 thread, and 29mm adjustable cushions.
Driven by a 4M310-10 valve (3/8" port, Cv 1.68, 4 cycles/s max), it operates on DC24V terminal entry with PT threads. The cylinder body rates to 1.0 MPa, but the assembled unit functions within the valve's 0.15-0.8 MPa window. At 0.5 MPa it delivers 3927N push force. A computed buyer insight: safe working load is roughly 2356N (60% of the 0.5MPa push), yielding a 200kg vertical lift capacity 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 (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 SAUF100X300-10B Is Used
Heavy Press Clamping
Decentralized clamping on a large press line. The integrated 4M310 valve handles the high 3927N push force locally without routing long tubing back to a central manifold.
Pallet Diverter
A 300mm stroke diverter on a heavy material conveyor. One DC24V signal actuates the 100mm bore directly at the station, saving manifold space and simplifying installation.
Automated Stacking Gate
Operating a heavy routing gate in an automated warehouse. The self-contained pneumatic actuator provides rapid 4 cycles/s shifting with a robust 1.68 Cv flow rate.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X300-10B the Right Choice?
When sizing, compare neighboring bores: the 80mm bore offers 2513N push while the 100mm bore provides 3927N push at 0.5 MPa. Always size force within the 0.15-0.8 MPa valve operating range, never the 1.0 MPa cylinder body rating. Confirm the DC24V terminal entry and PT thread meet your electrical specs. By default the rod retracts when energized; repositioning the valve switches it to extend-when-energized. Because this is a 300mm stroke, add external guides to prevent rod bending and side-load wear. The built-in valve routes air but does not lock the piston; for load holding on air loss, add an external rod lock or pilot-operated check valve. This SKU lacks a magnet (-S) and cannot accept magnetic switches.
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 SAUF100X300-10B FAQ
It generates 3927N push and 3681N pull at 0.5 MPa. The built-in valve is a 4M310-10 (3/8" port, Cv 1.68, max 4 cycles/s) running on a DC24V terminal coil. Although the cylinder body rates to 1.0 MPa, the assembled unit must operate within the valve's 0.15-0.8 MPa window. The cylinder port is 1/2".
Yes. The default action retracts the rod when the coil is energized. You can reconfigure it to extend-when-energized simply by repositioning the built-in valve on the cap. This allows flexible machine sequencing without altering your electrical controls.
