Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X100S-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X100S-08A 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-08A
The SAUF32X100S-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 cylinder, eliminating remote plumbing and saving a manifold slot. The 32mm bore delivers 402N push and 345N pull at 0.5MPa, operating safely within the valve's 0.15-0.8MPa window. The cylinder body rates to 1.0MPa but the assembled unit is capped by the valve.
This AC220V terminal-entry coil offers IP65 protection and a 16mm2 flow (Cv 0.89) at 5 cycles/s. The bore uses a 1/8" cylinder port and M10x1.25 rod thread. The S suffix adds a piston magnet for CMSG/DMSG/EMSG switches. Based on the 402N push force, the safe working load is roughly 241N, and it can vertically lift about 20kg 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 (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-08A Is Used
Decentralized Clamping
Ideal for a machining cell where each clamping station uses one coil signal to actuate independently, saving manifold space.
Inline Diverting
Perfect for a conveyor diverter arm that needs self-contained switching without running long air lines back to a central control panel.
Compact Part Ejection
Fits into tight assembly machine spaces, using the built-in valve and 21mm cushions to eject parts smoothly at up to 5 cycles/s.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X100S-08A the Right Choice?
Size this 32mm bore against the 40mm option (628N push at 0.5MPa) if you need more force, or step down if less is required. Confirm the AC220V terminal entry and PT threads match your system. The rod retracts when the coil is energised; reposition the valve to switch to extend-when-energised. Always size force within the 0.15-0.8MPa valve range, not the 1.0MPa cylinder body rating. The built-in valve routes air and is not a lock—add an external rod lock or pilot-operated check valve to hold loads. For this 100mm stroke, side-load is minimal, but for strokes over 300mm, use SC-series mounting accessories and guide rods to prevent binding.
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-08A FAQ
It pushes 402N and pulls 345N at 0.5MPa. The built-in valve is a 4M210-08 (1/4" port, Cv 0.89, 5 cycles/s) with an AC220V terminal-entry coil. Although the cylinder body rates to 1.0MPa, the assembled unit must operate within the valve's 0.15-0.8MPa range.
No remote valve is needed; the integrated 5/2 valve switches the cylinder from one coil signal. By default, the rod retracts when the coil is energised. You can reconfigure it to extend-when-energised simply by repositioning the valve.
