Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X100S-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X100S-08B is a genuine double-acting profile-type cylinder with a Ø32mm bore, 100mm 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 SAUF32X100S-08B
The SAUF32X100S-08B is a double-acting profile cylinder with a built-in AirTAC 4M210-08 5/2 solenoid valve on the cap. One DC24V 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. It features a 1/8" cylinder port, an M10x1.25 rod thread, and a 21 mm adjustable cushion.
Size force strictly within the valve's 0.15-0.8 MPa operating window, even though the cylinder body rates to 1.0 MPa. At 0.5 MPa it delivers 402 N push and 345 N pull. The 1/4" valve port yields a 16 mm2 flow (Cv 0.89) with a max frequency of 5 cycles/sec. The computed safe working load is roughly 241 N, and it can vertically lift about 20 kg with a 2:1 margin. The S suffix denotes a piston magnet for CMSG/DMSG/EMSG sensors.

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 SAUF32X100S-08B Is Used
Compact Part Ejection
Mounts directly at the ejection point on a CNC lathe. The integrated DC24V valve triggers the 32 mm rod to push parts out without running long tubing back to a central manifold.
Decentralized Diverter Gate
Ideal for routing small packages on a conveyor line. One coil signal switches the 4M210 valve locally, saving manifold space and simplifying installation.
Pick And Place Head
Drives a small vertical pick and place head. The built-in magnet supports position sensing, while the compact profile saves vertical space compared to standard cylinders.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X100S-08B the Right Choice?
Compare this 32 mm bore against the 40 mm neighbor (628 N push at 0.5 MPa) if your load exceeds the 241 N safe working threshold. Confirm the DC24V terminal entry and PT threads match your control scheme. Default action retracts the rod when energized, but you can reposition the valve to extend on signal. The assembled unit operates at 0.15-0.8 MPa, so never size using the 1.0 MPa cylinder body rating. The internal valve only routes air, so add an external rod lock or pilot-operated check valve to hold loads safely. For this 100 mm stroke side-load is minimal, but always guide rods for strokes over 300 mm.
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 SAUF32X100S-08B FAQ
It generates 402 N push and 345 N pull at 0.5 MPa. The built-in valve is a 4M210-08 (1/4" port, Cv 0.89, 5/2 solenoid) running on DC24V. You must size the force within the valve's 0.15-0.8 MPa operating window, not the 1.0 MPa cylinder body rating.
Yes. The default action retracts the rod upon energizing the coil, but you can reconfigure it to extend by physically repositioning the built-in valve. This allows you to adapt the fail-safe state to your machine logic without extra parts.
