Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X175-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X175-08A is a genuine double-acting profile-type cylinder with a Ø40mm bore, 175mm stroke and a built-in 4M210-08 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 SAUF40X175-08A
The SAUF40X175-08A is a double-acting profile cylinder with a built-in AirTAC 4M210-08 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 1/4" cylinder port, an M12x1.25 rod thread, and 21 mm adjustable cushions.
Operating within the valve's 0.15-0.8 MPa window, it delivers 628 N push and 528 N pull at 0.5 MPa. The integrated valve provides a 1/4" port, 16 mm2 flow (Cv 0.89), and handles up to 5 cycles per second. For sizing, the safe working load is roughly 377 N, allowing a vertical lift of about 32 kg with a 2:1 margin. This terminal-entry AC220V coil (IP65) retracts the rod by default.

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 (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 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 SAUF40X175-08A Is Used
Decentralized Clamping
Ideal for clamping stations on a large machining line where running individual lines back to a main manifold is impractical.
Inline Diverter Gate
Powers a routing flap on a conveyor. The integrated valve keeps response time under 0.05 s for fast package sorting.
Independent Lifting Pin
Drives a localized lifting pin on a storage shuttle. One AC220V signal actuates the mechanism without extra tubing.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X175-08A the Right Choice?
Size this 40 mm bore against the neighbouring 32 mm and 50 mm options, using the 628 N push force at 0.5 MPa to match your load. Confirm the AC220V voltage and terminal entry suit your control system. The default action retracts the rod when energised, but you can reposition the valve to extend on signal. Always size force within the 0.15-0.8 MPa valve range, not the 1.0 MPa cylinder body rating. Because the valve only routes air, add an external rod lock or pilot-operated check valve for load holding. For this 175 mm stroke, 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 SAUF40X175-08A FAQ
It pushes 628 N and pulls 528 N at 0.5 MPa. The built-in valve is a 4M210-08 (Cv 0.89, 1/4" port) running on AC220V. Although the cylinder body rates to 1.0 MPa, you must size force within the valve's 0.15-0.8 MPa operating window.
This SKU lacks the -S magnet suffix, so it cannot take a magnetic switch. Additionally, the built-in valve only routes air; it is not a lock. The rod will drift on air loss, so fit an external rod lock or pilot-operated check valve to hold a load.
