Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X300S-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X300S-08A is a genuine double-acting profile-type cylinder with a Ø50mm bore, 300mm 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 SAUF50X300S-08A
The SAUF50X300S-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 pushes 982N and pulls 825N at 0.5MPa. It includes a piston magnet for CMSG/DMSG/EMSG switches.
The integrated valve provides 1/4" porting with 16mm2 flow (Cv 0.89) and handles up to 5 cycles per second. The cylinder body rates to 1.0MPa, but the assembled unit operates within the valve's 0.15-0.8MPa window. The AC220V terminal entry coil is IP65 rated. For sizing, the safe working load is roughly 589N (60% of the 0.5MPa push force), yielding a vertical lift capacity of about 50kg 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 SAUF50X300S-08A Is Used
Diverter Gate Actuation
Drives a routing flap directly at the conveyor lane. The integrated valve eliminates long tube runs back to a central manifold, ensuring rapid 5 cycle/s response.
Decentralized Package Stopper
Deploys a stopper blade on a packaging line. One AC220V signal controls the 300mm stroke locally, saving manifold space and simplifying machine wiring.
Independent Tooling Slide
Moves a secondary tooling carriage on a large assembly machine. The self-contained 4M210-08 valve allows standalone control without extra plumbing.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X300S-08A the Right Choice?
Size by checking both neighboring bores: the 40mm bore yields 628N push while the 63mm bore yields 1559N at 0.5MPa. This 50mm unit provides 982N push and 825N pull at 0.5MPa. Confirm the AC220V voltage, terminal entry, and PT threads match your supply. The default action retracts the rod when energized; you can reconfigure it to extend by repositioning the valve. Always size force within the 0.15-0.8MPa valve range, never the 1.0MPa cylinder body limit. The built-in valve routes air and is not a lock; add an external rod lock or pilot-operated check valve to hold loads. The 1/4" cylinder port matches the valve port. For this 300mm 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 SAUF50X300S-08A FAQ
It pushes 982N and pulls 825N at 0.5MPa. The built-in valve is a 4M210-08 (1/4" port, Cv 0.89, 5/2 solenoid) running on AC220V with terminal entry. Although the cylinder body rates to 1.0MPa, the assembled unit must operate within the valve's 0.15-0.8MPa window.
The default action retracts the rod when the coil is energized. You can reconfigure it to extend-when-energized by repositioning the built-in valve. The valve only routes air; it does not function as a load lock, so add an external rod lock if you need to hold a load.
