Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X600S-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X600S-08A is a genuine double-acting profile-type cylinder with a Ø40mm bore, 600mm 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 SAUF40X600S-08A
The SAUF40X600S-08A is a double-acting profile cylinder with a built-in AirTAC 4M210-08 5/2 solenoid valve on the cap. One AC220V coil signal drives the actuator, eliminating remote plumbing and saving a manifold slot. The extruded aluminum barrel makes it shorter than a standard ISO cylinder of the same bore. It features a 1/4" valve port, 1/4" cylinder port, and a piston magnet for CMSG/DMSG/EMSG switches.
Operating within the 0.15-0.8 MPa valve window, it delivers 628 N push and 528 N pull force at 0.5 MPa. The integrated valve flows 16 mm2 (Cv 0.89) at up to 5 cycles per second. For sizing, the safe working load is roughly 377 N (about 60% of the 0.5 MPa push force), translating to a vertical lift capacity of about 32 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 (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 SAUF40X600S-08A Is Used
Conveyor Diverter Gate
Decentralized diverter on a packaging line. One AC220V signal actuates the 600 mm stroke to route boxes without running long tubing back to a central manifold.
Vertical Material Lift
Lifting components up to 32 kg. The built-in 4M210-08 valve handles the 5/2 switching directly at the load, simplifying installation in tight rack spaces.
Machine Tool Loading
Pushing parts into a machining center. The profile barrel saves space while the integrated magnet allows position confirmation via CMSG/DMSG reed switches.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X600S-08A the Right Choice?
Size by comparing neighbor bores: the 32 mm bore yields 402 N push at 0.5 MPa, while the 50 mm bore reaches 982 N. This 40 mm bore provides 628 N push, making it ideal for mid-range loads. Always size force within the 0.15-0.8 MPa valve operating range, as the cylinder body rates to 1.0 MPa but the assembled unit is limited by the valve. Confirm the AC220V terminal entry and PT thread match your supply. The default action retracts the rod when energized, but repositioning the valve changes it to extend-when-energized. For the 600 mm stroke, use external guides to prevent rod bending and side-load damage. The valve routes air and is not a load lock; add an external rod lock or pilot-operated check valve to hold loads securely.
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 SAUF40X600S-08A FAQ
It delivers 628 N push and 528 N pull at 0.5 MPa. The built-in valve is a 4M210-08 (1/4" port, Cv 0.89, 5/2 solenoid) running on AC220V with terminal entry. The cylinder body rates to 1.0 MPa, but you must size force within the 0.15-0.8 MPa valve operating window.
No, the built-in valve routes air and is not a load lock. If air is lost, the piston drifts and the 21 mm cushions only decelerate near stroke end. For load holding, install an external rod lock or pilot-operated check valve. The default action retracts when energized, but you can reposition the valve to extend when energized.
