Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X80-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X80-08A 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 SAUF32X80-08A
The SAUF32X80-08A 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 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 uses a 1/8" cylinder port, an M10x1.25 rod thread, and 21mm adjustable cushions.
Operating within the 0.15-0.8 MPa valve window, it delivers 402N push and 345N pull at 0.5 MPa. The 1/4" valve port gives 16mm2 flow (Cv 0.89) at up to 5 cycles per second. The AC220V terminal coil is IP65 rated. For sizing, the safe working load is roughly 241N, and vertical lift is about 20kg with a 2:1 margin. This SKU lacks a magnet, so it cannot take 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 SAUF32X80-08A Is Used
Decentralized Clamping
Ideal for a clamping station on a large machine, switching directly from one AC220V signal without tubing back to a central manifold.
Inline Diverting
Perfect for a short-stroke diverter gate where the 5 cycles per second speed and compact profile fit tight transfer spaces.
Modular Pick-and-Place
Suits a decentralized assembly cell, saving manifold slots and PU tubing by mounting the 4M210 valve directly on the cap.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X80-08A the Right Choice?
Size against the 40mm bore if you need more force, or drop to a smaller profile if load is light. At 0.5 MPa this 32mm bore pushes 402N and pulls 345N. Confirm the AC220V terminal entry suits your control voltage. The default action retracts the rod when energised; repositioning the valve changes it to extend-when-energised. Always size force within the 0.15-0.8 MPa valve range, not the 1.0 MPa 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 a load. For this 80mm stroke, side-load guides are not critical, but ensure alignment for smooth cushioning.
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 SAUF32X80-08A FAQ
It pushes 402N and pulls 345N at 0.5 MPa. The built-in valve is a 4M210-08 5/2 solenoid with a 1/4" port, Cv 0.89, and a 5 cycles/s limit. The coil is AC220V with terminal entry. You must size force within the 0.15-0.8 MPa valve operating window, even though the cylinder body rates to 1.0 MPa.
No, the built-in valve only routes air and is not a load lock; the piston drifts on air loss. Add an external rod lock or pilot-operated check valve for holding. By default the rod retracts when the coil energises, but you can reposition the valve to extend-when-energised.
