Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X125S-10B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X125S-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 SAUF100X125S-10B
The SAUF100X125S-10B is a double-acting profile cylinder with a built-in AirTAC 4M310-10 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 version uses a 1/2" cylinder port with an M20x1.5 rod thread, and the S suffix means a piston magnet is present for CMSG/DMSG/EMSG sensors.
Operating in the 0.15-0.8 MPa valve window, it delivers 3927N push at 0.5MPa. For sizing, the safe working load is roughly 2356N (60% of the 0.5MPa figure), and the vertical lift capacity is about 200kg with a 2:1 margin. The 3/8" valve port flows 30mm2 (Cv 1.68) at up to 4 cycles/s. The DC24V terminal coil offers IP65 protection and a 0.05s response. Note the cylinder body rates to 1.0MPa but the integrated valve limits the assembled unit to 0.8MPa.

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 SAUF100X125S-10B Is Used
Decentralized Press Clamping
Uses the built-in 4M310 valve to clamp heavy parts directly at the press station, eliminating long tubing runs back to a central manifold.
Heavy Sorter Diverter
Provides high-force package diversion on high-speed conveyors, switching locally at 4 cycles/s without consuming manifold slots.
Pallet Lift Station
Lifts pallets vertically using the 200kg safe lift capacity, with the integrated magnet allowing precise position confirmation.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X125S-10B the Right Choice?
When sizing this model, compare against the 80mm bore (2513N push at 0.5MPa) or larger custom setups, using the 3927N push figure at 0.5MPa for your baseline. Verify the DC24V terminal entry and PT threads match your control system. The default action retracts the rod when energised, but you can reconfigure it to extend-when-energised by repositioning the valve. Because the 4M310 valve only routes air, it is not a load lock; add an external rod lock or pilot-operated check valve if you need to hold a load against air loss. The 125mm stroke is above the 75mm SAUF minimum, and since it is under 300mm, side-load guides are less critical but still recommended for rigid mounting.
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 SAUF100X125S-10B FAQ
It generates 3927N push and 3681N pull at 0.5MPa, reaching 6282N push at 0.8MPa. The built-in valve is a 4M310-10 (3/8" port, Cv 1.68, 30mm2 flow) with a DC24V terminal coil. Although the cylinder body rates to 1.0MPa, the assembled unit must operate within the valve's 0.15-0.8MPa window.
No, the built-in 5/2 valve routes air but does not lock the piston. If air is lost, the load will drift. You must add an external rod lock or pilot-operated check valve for holding. The default action retracts when energised, but you can swap it to extend-when-energised by repositioning the valve.
