Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X500-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X500-08B is a genuine double-acting profile-type cylinder with a Ø100mm bore, 500mm stroke and a built-in 4M310-08 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 SAUF100X500-08B
The SAUF100X500-08B 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 unit of the same bore. This 100mm bore features a 1/2 inch cylinder port, a 25mm rod, and 29mm adjustable cushions.
Operating within the 0.15-0.8 MPa valve window, it delivers 3927 N push force at 0.5 MPa. The integrated valve has a 1/4 inch port, Cv 1.4 flow, and switches up to 4 cycles/sec. The DC24V terminal coil is IP65 rated. For sizing, the safe working load is roughly 2356 N, and vertical lift capacity is about 200 kg 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 SAUF100X500-08B Is Used
Heavy Stamping Press
Decentralized actuation for a heavy stamping station. The built-in 4M310 valve handles the 3927 N push force directly at the cap, eliminating long tubing runs from a central manifold.
Pallet Diverter Gate
One-valve-per-actuator setup for a 500mm pallet routing gate. The DC24V coil switches the diverter locally, saving manifold slots while managing the 100mm bore flow.
Vertical Material Lift
Lifting components in a high-bay warehouse. Sized for a 200kg vertical lift with a 2:1 margin at 0.5 MPa, operating safely inside the 0.15-0.8 MPa valve pressure window.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X500-08B the Right Choice?
Size against the 63mm and 100mm bores: this 100mm unit provides 3927 N push at 0.5 MPa versus 1559 N on the 63mm. Confirm the DC24V terminal entry and PT threads suit your control panel. The default action retracts the rod when energised, but repositioning the valve switches it to extend-when-energised. Always size force within the 0.15-0.8 MPa valve range, never the 1.0 MPa cylinder body rating. Because this SKU lacks a magnet, it cannot take a magnetic switch. For the 500mm stroke, use external guides to prevent rod bending and side-load wear. The valve routes air; it is not a lock, so add an external rod lock or pilot-operated check valve to hold loads safely.
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 SAUF100X500-08B FAQ
It delivers 3927 N push and 3681 N pull at 0.5 MPa. The built-in valve is a 4M310-08 (1/4 inch port, Cv 1.4, max 4 cycles/sec). The DC24V coil has a terminal entry. You must size force within the 0.15-0.8 MPa valve operating window, even though the cylinder body rates to 1.0 MPa.
No. The built-in 5/2 valve routes air; it is not a load lock. If air is lost or the valve is centered, the piston drifts and the 29mm cushion only decelerates near stroke end. To hold a load safely, install an external rod lock or a pilot-operated check valve.
