Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X450S-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X450S-08A is a genuine double-acting profile-type cylinder with a Ø50mm bore, 450mm 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 SAUF50X450S-08A
The SAUF50X450S-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 50mm bore has a 1/4" cylinder port, an M16x1.5 rod 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 range, it delivers 982N push and 825N pull at 0.5 MPa. The integrated valve flows 16 mm2 (Cv 0.89) at up to 5 cycles/sec. For sizing, the safe working load is roughly 589N, allowing a vertical lift of about 50kg with a 2:1 margin. The AC220V terminal coil is IP65 rated. Remember the valve routes air; it is not a load lock.

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 SAUF50X450S-08A Is Used
Decentralized Conveyor Diverter
Installs directly on a conveyor lane to push cartons. The integrated valve eliminates long tube runs back to a central manifold, cutting response time.
Independent Stacking Gate
Powers a 450mm stroke sorting flap in a high-density facility. One AC220V signal cycles the gate, freeing up manifold slots for other actuators.
Machine Tool Loader
Drives a part push-off arm on a machining center. The built-in 4M210-08 valve handles 5 cycles/sec, ideal for localized actuation without extra plumbing.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X450S-08A the Right Choice?
Size this 50mm bore against the neighbours: a 40mm bore gives 628N push while a 63mm bore yields 1559N at 0.5 MPa. Confirm the AC220V terminal entry and PT thread match your supply. The default action retracts the rod when energised, but you can reconfigure it to extend by repositioning the valve. Always size force within the 0.15-0.8 MPa valve window, not the 1.0 MPa cylinder body rating. Because the 450mm stroke invites rod bending, use an external guide to manage side loads. For load holding on air loss, add 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 SAUF50X450S-08A FAQ
It pushes 982N and pulls 825N at 0.5 MPa. The built-in valve is a 4M210-08 (1/4" port, Cv 0.89, 5 cycles/sec) with an AC220V terminal coil. Although the cylinder body rates to 1.0 MPa, the assembled unit must operate in the 0.15-0.8 MPa valve window.
Yes. The default action retracts the rod on coil energisation, but you can swap it to extend-when-energised by repositioning the valve. The valve only routes air; it is not a lock, so the piston will drift on air loss. Add an external rod lock for load holding.
