Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X175S-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X175S-08B is a genuine double-acting profile-type cylinder with a Ø100mm bore, 175mm 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 SAUF100X175S-08B
The SAUF100X175S-08B is a double-acting profile cylinder with a built-in AirTAC 4M310-08 5/2 solenoid valve on the cap. One coil signal drives the actuator, eliminating remote valves and saving a manifold slot. The extruded aluminum barrel is shorter than an ISO 15552 cylinder of the same bore. The -S suffix provides a piston magnet for CMSG/DMSG/EMSG switches.
At 0.5 MPa it delivers 3927 N push and 3681 N pull force. The cylinder body rates to 1.0 MPa, but the integrated valve restricts the working pressure to 0.15-0.8 MPa. The 1/4" valve port yields a Cv of 1.4 and 4 cycles/sec. The bore dictates a 1/2" cylinder port. Computed insight: safe working load is roughly 2356 N, allowing a 200 kg vertical lift 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 SAUF100X175S-08B Is Used
Machine Tool Clamping
Decentralized clamping on a large machining center. The built-in 4M310 valve switches the 100 mm bore directly from one DC24V signal, saving manifold space.
Pallet Stop Gate
Independent stop gate on a conveyor line. One coil signal actuates the gate without extra tubing to a central panel, simplifying the pneumatic layout.
Heavy Parts Ejector
Ejecting heavy parts from a press. The 3927 N push force at 0.5 MPa handles rigid ejection, while the integrated valve ensures fast local response.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X175S-08B the Right Choice?
Size by checking both neighboring bores: the 80 mm bore yields 2513 N push while the 100 mm bore yields 3927 N push at 0.5 MPa. Confirm the DC24V terminal entry and PT thread meet your control specs. The rod retracts when the coil is energized, but you can reposition the valve to extend on energization. Size force strictly within the 0.15-0.8 MPa valve window, never the 1.0 MPa cylinder rating. The valve routes air and does not hold the load on pressure loss; add an external rod lock or pilot-operated check valve for suspended loads. For this 175 mm stroke, side-load is minimal, but always guide the rod end.
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 SAUF100X175S-08B FAQ
It pushes 3927 N and pulls 3681 N at 0.5 MPa. The built-in valve is a 4M310-08 5/2 solenoid with a 1/4" port, Cv 1.4, and 4 cycles/sec. The coil is DC24V with terminal entry. The cylinder body rates to 1.0 MPa, but the assembled unit operates strictly within a 0.15-0.8 MPa window.
By default the rod retracts when the coil is energized. You can reconfigure it to extend when energized by repositioning the valve. Because the valve only routes air, it is not a load lock; use an external rod lock or pilot-operated check valve to hold a suspended load.
