Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X125-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X125-08B is a genuine double-acting profile-type cylinder with a Ø100mm bore, 125mm 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 SAUF100X125-08B
The AirTAC SAUF100X125-08B is a double-acting profile-type cylinder with a built-in 4M310 5/2 solenoid valve directly 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. It features a 100mm bore, 125mm stroke, 1/2" cylinder port, and M20x1.5 rod thread.
Operating within the valve's 0.15-0.8 MPa window, it delivers 3927 N push force at 0.5 MPa. A practical computed insight: safe working load is roughly 2356 N (60% of the 0.5 MPa push), allowing a vertical lift of about 200 kg with a 2:1 margin. The integrated 4M310-08 valve has a 1/4" port, Cv 1.4, and cycles up to 4 times per second. This DC24V terminal-entry coil is IP65 rated. Since this SKU lacks the -S magnet suffix, it cannot accept a magnetic switch.

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 SAUF100X125-08B Is Used
Decentralized Press Clamping
Ideal for large press lines where running individual air lines is costly. The built-in 4M310 valve actuates the clamp directly from one DC24V signal.
Heavy Transfer Diverters
Provides robust 3927 N push force at 0.5 MPa for diverting heavy pallets on a conveyor, saving manifold space by switching locally at the actuator.
Vertical Lift Gates
Handles vertical lifting up to 200 kg with a 2:1 safety margin. The compact profile fits tight structural gaps without remote valve plumbing.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X125-08B the Right Choice?
When sizing, compare neighboring bores: the 80mm bore yields 2513 N push at 0.5 MPa, while the 100mm bore provides 3927 N at the same pressure. 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 matches your control system. By default, the rod retracts when the coil is energized, but you can reconfigure it to extend-when-energised by repositioning the valve. The valve only routes air; it is not a load lock. For suspended loads, add an external rod lock or pilot-operated check valve. For strokes of 300mm or more, ensure adequate side-load guidance.
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 SAUF100X125-08B FAQ
It delivers 3927 N push and 3681 N pull at 0.5 MPa, reaching 6282 N push at 0.8 MPa. The built-in valve is a 4M310-08 (1/4" port, Cv 1.4, max 4 cycles/sec). It uses a DC24V terminal-entry coil. You must size force within the 0.15-0.8 MPa valve window, not the 1.0 MPa cylinder body rating.
No. The built-in 5/2 valve routes air but does not lock the piston. On air loss, the load drifts and the 29mm adjustable cushion only decelerates near stroke end. For load holding, install an external rod lock or pilot-operated check valve. Also, this SKU lacks the -S magnet, so it cannot use magnetic sensors.
