Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X80-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X80-08B is a genuine double-acting profile-type cylinder with a Ø32mm bore, 80mm 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 SAUF32X80-08B
The AirTAC SAUF32X80-08B is a double-acting profile cylinder with a built-in 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 makes it shorter than an ISO 15552 unit of the same bore. It features a 32mm bore, 80mm stroke, 1/8" cylinder port, and an M10x1.25 rod thread.
Operating within the valve's 0.15-0.8 MPa range, it delivers 402N push and 345N pull at 0.5 MPa. A computed buyer insight: the safe working load is roughly 241N (60% of the 0.5MPa push force), allowing a vertical lift of about 20kg with a 2:1 margin. The 1/4" valve port yields a 16mm2 flow (Cv 0.89) with a 5 cycle/s max frequency. This DC24V terminal-entry coil offers IP65 protection. Note this SKU lacks the -S magnet and cannot accept a sensor.

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 SAUF32X80-08B Is Used
Decentralized Clamping
Ideal for a machining fixture needing independent clamping. The built-in valve means one DC24V signal actuates the clamp without running long tubing back to a central manifold.
Component Sorting Gate
Perfect for a diverter gate on a conveyor. The compact 32mm profile fits tight spaces, and the integrated 4M210 valve switches the gate at up to 5 cycles/s.
Modular Pick-and-Place
Great for a small vertical lift in a modular assembly cell. Lifting about 20kg with a 2:1 safety margin, the self-contained design simplifies cell integration.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X80-08B the Right Choice?
Size by comparing neighbouring bores: the 32mm bore gives 402N push at 0.5MPa, while stepping up to 40mm yields 628N. Confirm the DC24V terminal entry and PT threads match your supply. The default action retracts the rod when energised; reposition the valve to switch to extend-when-energised. Always size force within the 0.15-0.8 MPa valve window, not the 1.0 MPa cylinder body rating. Because the valve only routes air, it is not a load lock—add an external rod lock or pilot-operated check valve to hold loads. For this 80mm stroke side-load is minimal, but for strokes >=300mm guide the rod 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 SAUF32X80-08B FAQ
It generates 402N push and 345N pull at 0.5MPa. The built-in valve is a 4M210-08 (5/2 solenoid) with a 1/4" port, 16mm2 flow (Cv 0.89), and a 5 cycle/s max frequency. The DC24V coil runs on a 0.15-0.8 MPa operating window. The cylinder body rates to 1.0MPa but the assembled unit must stay within the valve's 0.8MPa limit.
By default the rod retracts when the coil is energised, but you can reposition the valve to extend-when-energised. The valve only routes air, so it is not a load lock; the piston drifts on air loss. For load holding, install an external rod lock or pilot-operated check valve.
