Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X125-10B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X125-10B is a genuine double-acting profile-type cylinder with a Ø100mm bore, 125mm 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 SAUF100X125-10B
The SAUF100X125-10B 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 makes it shorter than an ISO 15552 cylinder of the same bore. It features a 1/2 inch cylinder port, an M20x1.5 rod thread, and 29 mm adjustable cushions.
Operating in the 0.15-0.8 MPa valve window, it delivers 3927 N push and 3681 N pull at 0.5 MPa. The integrated 4M310-10 valve has a 3/8 inch port, Cv 1.68, and handles up to 4 cycles per second. The DC24V coil offers IP65 protection with terminal entry. For sizing, the safe working load is roughly 2356 N, allowing a vertical lift of 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 SAUF100X125-10B Is Used
Heavy Clamping Station
Decentralized clamping on a large machining line where the integrated valve provides immediate high-force actuation without routing long tubing back to a central manifold.
Pallet Stop Gate
Independent pallet diversion gate that switches directly from one coil signal, saving manifold slots while providing robust 100 mm bore stopping force.
Product Reject Arm
Localized reject pusher on a high-speed conveyor where the built-in 4M310 valve ensures rapid 4 cycles per second operation directly at the point of action.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X125-10B the Right Choice?
Size this 100 mm bore against the 80 mm option (push 2513 N at 0.5 MPa) or the 63 mm option (push 1559 N). Confirm the DC24V coil and terminal entry suit your control system. The rod retracts when energised by default, but you can reposition the valve to extend on signal. Because the cylinder body rates to 1.0 MPa but the valve runs 0.15-0.8 MPa, always size force within that lower window. The valve only routes air; it is not a lock, so add an external rod lock or pilot-operated check valve to hold a load. This 125 mm stroke is above the 75 mm minimum and below 300 mm, so standard side-load guidance applies. Without the -S suffix, this SKU cannot take a magnetic switch.
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 SAUF100X125-10B FAQ
It pushes 3927 N and pulls 3681 N at 0.5 MPa. The built-in valve is a 4M310-10 with a 3/8 inch port and Cv 1.68. The DC24V coil operates at 0.15-0.8 MPa, so never size the assembled unit using the 1.0 MPa cylinder body rating.
No, the built-in valve routes air but does not lock the piston. The rod retracts when energised by default, but you can reposition the valve to extend on signal. For vertical load holding, you must add an external rod lock or pilot-operated check valve.
