Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X600S-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X600S-08A is a genuine double-acting profile-type cylinder with a Ø50mm 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 SAUF50X600S-08A
The SAUF50X600S-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 is shorter than an ISO 15552 cylinder of the same bore. The -S suffix means a piston magnet is present for CMSG/DMSG/EMSG switches.
It delivers 982 N push and 825 N pull at 0.5 MPa. The cylinder body rates to 1.0 MPa, but the assembled unit operates strictly within the valve's 0.15-0.8 MPa window. The 1/4" valve port yields a 16 mm2 flow (Cv 0.89) with a 5 cycle/s limit. The bore's air port is 1/4" with a PT thread. Computed insight: safe working load is roughly 589 N (60% of the 0.5 MPa push), allowing a vertical lift of about 50 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 (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa | 1374 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 SAUF50X600S-08A Is Used
Divert Gate Actuation
Decentralized sorting line diverters where one coil signal per gate eliminates long tubing runs back to a central manifold.
Vertical Package Lift
Lifting stations using the 50 kg vertical capacity, benefiting from the self-contained valve to reduce cabinet complexity.
Machine Guard Door
Automated access doors on large machinery, saving manifold slots and simplifying installation with the integrated 4M210 valve.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X600S-08A the Right Choice?
When sizing, compare this 50 mm bore against the 40 mm and 63 mm neighbors. The 40 mm yields 628 N push while the 63 mm provides 1559 N at 0.5 MPa. This 50 mm unit provides 982 N push, making it a solid middle ground. Confirm the AC220V terminal entry and PT thread meet your electrical specs. The default action retracts the rod when energised, but you can reposition the valve to extend on signal. Size all forces within the 0.15-0.8 MPa valve range. Because the 600 mm stroke is long, add external guides to prevent rod bending and side-load wear. The valve routes air and is not a lock; if power or air drops, the cushion only decelerates near stroke end. For suspended loads, install an external rod lock or pilot-operated check valve.
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 SAUF50X600S-08A FAQ
It delivers 982 N push and 825 N pull at 0.5 MPa. The built-in valve is a 4M210-08 with a 1/4" port, Cv 0.89, and 5 cycle/s max. The coil is AC220V with terminal entry. Although the cylinder body rates to 1.0 MPa, the assembled unit must operate in the 0.15-0.8 MPa valve window.
By default the rod retracts when the coil is energised, but you can reposition the valve to extend on signal. The 5/2 valve routes air and is not a load lock. If air is lost, the rod drifts and the 21 mm cushion only decelerates near stroke end. Use an external rod lock or pilot-operated check valve for suspended loads.
