Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X50S-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X50S-08B is a genuine double-acting profile-type cylinder with a Ø32mm bore, 50mm 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 SAUF32X50S-08B
The SAUF32X50S-08B is a double-acting profile-type cylinder with a built-in AirTAC 4M 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 cylinder of the same bore. The bore dictates a 1/8 inch cylinder port and an M10x1.25 rod thread, while the valve port is 1/4 inch.
Operating in the 0.15-0.8 MPa valve window, it delivers 402 N push force at 0.5 MPa. The integrated 4M210-08 valve provides 16 mm2 flow (Cv 0.89) and handles 5 cycles per second. The DC24V terminal coil is IP65 rated. For sizing, expect a safe working load near 241 N, or a vertical lift capacity around 20 kg with a 2:1 margin. The S suffix denotes a piston magnet for CMSG/DMSG/EMSG switches.

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 (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 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 SAUF32X50S-08B Is Used
Modular Assembly Cells
Distributes individual clamp signals across a large machine without routing tubing back to a central manifold.
Small Part Ejection
Uses the compact 32 mm profile and 5 cycle/s valve frequency to push parts out of a tight fixture space.
Diverter Gates
Powers short-stroke sorting flaps directly at the conveyor edge, saving installation time with self-switching logic.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X50S-08B the Right Choice?
Size by checking both neighboring bores: the 32 mm bore yields 402 N push at 0.5 MPa, while the next size up provides 628 N. Confirm the DC24V terminal entry and 1/4 inch valve port fit your supply. The cylinder body rates to 1.0 MPa, but size force strictly within the 0.15-0.8 MPa valve range. The rod retracts by default when energized; reposition the valve to extend on signal. Because the valve only routes air, add an external rod lock or pilot-operated check valve to hold loads safely. For strokes 300 mm or longer, guide the load to prevent 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 SAUF32X50S-08B FAQ
It delivers 402 N push force at 0.5 MPa within a 0.15-0.8 MPa pressure window. The built-in valve is a 4M210-08 with 1/4 inch port and Cv 0.89. The coil is DC24V with terminal entry. The cylinder bore is 32 mm with a 1/8 inch cylinder port.
Yes. The default action retracts the rod on signal, but you can reconfigure it to extend when energized by repositioning the built-in valve. This allows flexible decentralized control without extra remote valves.
