Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X700S-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X700S-08A is a genuine double-acting profile-type cylinder with a Ø50mm bore, 700mm 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 SAUF50X700S-08A
The SAUF50X700S-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 makes it shorter than an ISO 15552 unit of the same bore. This 50mm bore model uses a 1/4" cylinder port, features a 700mm stroke, and includes a piston magnet for CMSG/DMSG/EMSG switches.
Size force strictly within the 0.15-0.8 MPa valve operating window, even though the cylinder body rates to 1.0 MPa. At 0.5 MPa it delivers 982N push and 825N pull. The 4M210-08 valve provides 16mm2 flow (Cv 0.89) and handles 5 cycles/sec. For sizing, the safe working load is roughly 589N (60% of the 0.5MPa push), and it can vertically lift about 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 SAUF50X700S-08A Is Used
Decentralized Conveyor Divert
Mounts directly at the divert station to push packages without routing long tube runs back to a central manifold.
Machine Tool Loading
Drives a 700mm stroke loading arm into a lathe, switching itself locally via the built-in 4M210-08 valve for fast response.
Vertical Package Lift
Lifts components up to 50kg using the 50mm bore, relying on the integrated magnet for precise end-of-stroke confirmation.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X700S-08A the Right Choice?
When sizing, compare both directions: this 50mm bore pushes 982N and pulls 825N at 0.5MPa, sitting between the 40mm (628N push) and 63mm (1559N push) options. Confirm the electrical setup: this SKU uses an AC220V terminal entry coil. Default action retracts the rod when energised, but you can reposition the valve to extend-when-energised. Always operate within the 0.15-0.8 MPa valve range, not the 1.0 MPa cylinder rating. The valve only routes air, so add an external rod lock or pilot-operated check valve to hold loads. For the 700mm 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 SAUF50X700S-08A FAQ
It uses a 4M210-08 valve (Cv 0.89, 16mm2 flow, 5 cycles/sec) with an AC220V terminal coil. The 50mm bore delivers 982N push at 0.5MPa. You must size force within the 0.15-0.8 MPa valve window, as the 1.0 MPa cylinder body rating does not apply to the assembled unit.
By default the rod retracts when the coil is energised, but you can reposition the valve to extend-when-energised. The 5/2 valve only routes air; it is not a lock. On air loss the piston drifts, so fit an external rod lock or pilot-operated check valve for load holding.
