Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X800-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X800-08A is a genuine double-acting profile-type cylinder with a Ø50mm bore, 800mm 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 SAUF50X800-08A
The SAUF50X800-08A is an extruded aluminum profile-type double-acting 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. It is shorter than an ISO 15552 cylinder of the same bore. This SKU uses terminal entry with PT threads and has no magnet, so it cannot accept a magnetic switch.
Operating in the 0.15-0.8 MPa valve window, it delivers 982 N push and 825 N pull at 0.5 MPa. The valve flows 16 mm2 (Cv 0.89) at up to 5 cycles/s. The cylinder body rates to 1.0 MPa but the assembled unit is capped by the valve. Based on the 0.5 MPa push force, the safe working load is about 589 N, and it can vertically lift roughly 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 SAUF50X800-08A Is Used
Decentralized Conveyor Diverter
Mounts directly at the divert lane. One AC220V signal actuates the 800 mm stroke to push cartons without tubing back to a central manifold.
Long-Reach Stack Gate
Ideal for opening wide access gates in storage modules. The built-in 4M210 valve handles the 5 cycles/s demand right at the actuator.
Independent Machine Guard
Drives a long safety guard on a packaging line. The self-contained 1/4" ported valve simplifies installation and removes manifold slot limits.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X800-08A the Right Choice?
Size between the 40 mm bore (628 N push @0.5 MPa) and the 63 mm bore (1559 N push @0.5 MPa). Confirm the AC220V terminal entry and 1/4" valve port. The cylinder port is 1/4". Default action retracts the rod when energised; reposition the valve to extend on signal. Size force within the 0.15-0.8 MPa valve range, never the 1.0 MPa cylinder rating. The valve routes air and is not a lock; add an external rod lock or pilot-operated check valve to hold a load. For the 800 mm 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 SAUF50X800-08A FAQ
It pushes 982 N and pulls 825 N at 0.5 MPa. The built-in valve is a 4M210-08 (Cv 0.89, 16 mm2 flow) running on AC220V with terminal entry. The cylinder body rates to 1.0 MPa, but you must size force within the valve's 0.15-0.8 MPa operating window. The cylinder air port is 1/4".
No. The built-in 5/2 valve routes air but does not lock the piston. On air loss the rod drifts. Add an external rod lock or pilot-operated check valve for load holding. Note this SKU lacks a magnet (-S) and cannot take a sensor.
