Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X500S-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X500S-08A is a genuine double-acting profile-type cylinder with a Ø32mm bore, 500mm 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 SAUF32X500S-08A
The SAUF32X500S-08A is a double-acting profile cylinder with a built-in AirTAC 4M210 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. This 32mm bore version uses a 1/8" cylinder port, a 1/4" valve port, and a Ø12mm rod with an M10x1.25 thread.
Operating within the 0.15-0.8 MPa valve window, it delivers 402N push force at 0.5MPa. The safe working load is roughly 241N, and it can vertically lift about 20kg with a 2:1 margin. The integrated valve flows 16mm2 (Cv 0.89) at up to 5 cycles per second. This AC220V terminal-entry coil is IP65 rated. The S suffix provides a piston magnet for CMSG/DMSG/EMSG switches. Air cushions span 21mm at each end.

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 SAUF32X500S-08A Is Used
Decentralized Sorting Diverter
Mounts directly on a conveyor line to push parcels. The integrated valve removes the need to run long tubes back to a central manifold, speeding up cycle response.
Independent Clamping Station
Ideal for a standalone machining cell. One AC220V signal actuates the clamp, freeing up valve manifold slots for other machine functions while handling the 500mm reach.
Vertical Package Stopper
Acts as a height barrier in a packaging line. The built-in magnet allows position confirmation, and the compact profile fits tight frame clearances easily.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X500S-08A the Right Choice?
When sizing, compare neighboring bores: the 40mm bore yields 628N push at 0.5MPa versus 402N here. Always size force within the 0.15-0.8 MPa valve range, never the 1.0MPa cylinder body rating. Confirm your coil is AC220V with terminal entry. The rod retracts when energized; reposition the valve to extend on signal. For this 500mm stroke, use external guides to prevent rod bending and side-load wear. The built-in valve routes air but does not lock the piston—add an external rod lock or pilot-operated check valve to hold loads securely.
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 SAUF32X500S-08A FAQ
It delivers 402N push and 345N pull at 0.5MPa. The built-in valve is a 4M210-08 (1/4" port, Cv 0.89, 5/2 solenoid) running on AC220V. You must size the force within the 0.15-0.8 MPa valve operating window, even though the cylinder body rates to 1.0MPa.
By default, the rod retracts when the coil receives the signal. You can reconfigure it to extend-when-energized simply by repositioning the integrated valve. This self-switching design means no remote valve is needed.
