Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X500S-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X500S-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 SAUF100X500S-08B
The SAUF100X500S-08B is a double-acting profile-type cylinder with a built-in AirTAC 4M310 5-port 2-position solenoid valve on the cap. One coil signal drives the cylinder, eliminating remote valves, extra tubing, and manifold slots for decentralized machine setups. The extruded aluminum barrel makes it shorter than an ISO 15552 cylinder of the same bore.
Featuring a 100mm bore, 500mm stroke, and a 1/2" cylinder port, it delivers a push force of 3927 N at 0.5 MPa. The integrated valve has a 1/4" port, Cv 1.4, and handles up to 4 cycles/sec. Based on the 0.5 MPa push figure, the computed safe working load is about 2356 N, with a vertical lift capacity of roughly 200 kg at a 2:1 margin. The DC24V terminal coil is IP65 rated. The -S suffix indicates a built-in 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 (Ø100mm)

|---|---|---|
| 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 SAUF100X500S-08B Is Used
Decentralized Press Clamping
Ideal for large presses needing individual actuator control, using the built-in valve to clamp heavy workpieces without routing long tubing back to a central manifold.
Heavy Material Diversion
Provides robust 100mm bore push force for diverting heavy pallets on a conveyor, switching itself locally via the 4M310 valve for rapid 4 cycle/sec actuation.
Automated Storage Gates
Excels in automated storage systems for opening heavy access gates, saving manifold slots while offering position feedback through the integrated piston magnet.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X500S-08B the Right Choice?
Size this 100mm bore against the neighboring 80mm option: the 100mm yields 3927 N push at 0.5 MPa versus 2513 N for the 80mm. Confirm the DC24V terminal entry and PT thread meet your control specs. The cylinder body rates to 1.0 MPa, but you must size force within the built-in valve's 0.15-0.8 MPa operating window. Default action retracts the rod when energized; reposition the valve to extend on energization. Because the valve only routes air, add an external rod lock or pilot-operated check valve for load holding. For the 500mm stroke, use external guides to prevent rod bending and side-load wear.
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 SAUF100X500S-08B FAQ
It delivers 3927 N push and 3681 N pull at 0.5 MPa, reaching 6282 N at 0.8 MPa. The built-in valve is a 4M310-08 (1/4" port, Cv 1.4, max 4 cycles/sec) with 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.
No, the built-in valve routes air but does not function as a load lock; the piston will drift on air loss. For load holding, you must add an external rod lock or pilot-operated check valve. The default action retracts the rod when energized, but you can reposition the valve to extend on energization.
