Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X500S-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X500S-08A is a genuine double-acting profile-type cylinder with a Ø50mm bore, 500mm 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 SAUF50X500S-08A
The SAUF50X500S-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 unit of the same bore. This 50mm bore uses a 1/4" cylinder port, a Ø20mm rod with an M16x1.5 thread, and 21mm adjustable cushions. The S suffix means a piston magnet is present for CMSG/DMSG/EMSG switches.
Operating in the 0.15-0.8 MPa valve window, it delivers 982N push and 825N pull at 0.5MPa. The integrated valve provides 16mm2 flow (Cv 0.89) and handles 5 cycles/sec. Computed buyer insight: safe working load is ~589N (60% of the 0.5MPa push), allowing a vertical lift of ~50kg with a 2:1 margin. The AC220V terminal entry coil is IP65 rated.

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 SAUF50X500S-08A Is Used
Decentralized Conveyor Divert
Mounts directly at the divert gate on a long conveyor line. The integrated 4M210-08 valve eliminates long tube runs back to a central manifold, improving cycle response.
Independent Machine Clamp
Ideal for a standalone clamping station on a large machine bed. One AC220V coil signal actuates the clamp without consuming a slot in the main valve bank.
Zoned Packaging Pusher
Perfect for a 500mm stroke pusher in a packaging cell. The built-in magnet allows precise end-position sensing via CMSG switches without external brackets.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X500S-08A the Right Choice?
Size by checking both neighbor bores: the 40mm bore gives 628N push while the 63mm bore gives 1559N push at 0.5MPa. This 50mm bore provides 982N push, yielding a ~589N safe working load. Confirm the AC220V terminal entry and PT threads suit your control panel. The default action retracts the rod when energized, but you can reposition the valve to extend-when-energized. Always size force within the 0.15-0.8 MPa valve range, not the 1.0 MPa cylinder body rating. The built-in valve routes air and is not a lock; for load holding on air loss, add an external rod lock or pilot-operated check valve. For the 500mm stroke, use external guides to prevent rod bending and side-load wear.
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 SAUF50X500S-08A FAQ
It delivers 982N push and 825N pull at 0.5MPa. The built-in valve is a 4M210-08 (1/4" port, Cv 0.89, 5 cycles/sec) driven by an AC220V terminal entry coil. Although the cylinder body rates to 1.0MPa, the assembled unit must operate in the 0.15-0.8MPa valve window.
Yes. The default action retracts the rod when the coil is energized, but you can reposition the valve to extend-when-energized. The valve only routes air; it is not a load lock. If you need to hold a vertical load during air loss, install an external rod lock or pilot-operated check valve.
