Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X80S-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X80S-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 SAUF32X80S-08B
The SAUF32X80S-08B 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 32mm bore delivers 402N push and 345N pull at 0.5MPa, operating within the valve's 0.15-0.8MPa window. The cylinder port is 1/8".
This DC24V terminal-entry unit includes a piston magnet for CMSG/DMSG switches. The integrated 4M210-08 valve has a 1/4" port, Cv 0.89, and handles 5 cycles/sec. Computed buyer insight: safe working load is roughly 241N (60% of the 402N push), yielding a 20kg vertical lift capacity 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 SAUF32X80S-08B Is Used
Decentralized Clamping
Ideal for distributed clamping stations where running a separate valve manifold would add excessive tubing cost and complexity.
Inline Diverters
Perfect for conveyor sorting gates that require independent actuation without dedicating a central valve island slot to each cylinder.
Compact Tooling
Fits directly onto end-of-arm tooling for simple pick-and-place tasks, minimising pneumatic plumbing on moving robot arms.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X80S-08B the Right Choice?
Size by force: the 32mm bore gives 402N push at 0.5MPa; step up to a 40mm bore for 628N if needed. The 80mm stroke is standard (min 50mm, max 1000mm). Confirm the DC24V coil and terminal entry suit your control system. The cylinder body rates to 1.0MPa, but size force within the valve's 0.15-0.8MPa limit. The 4M210 valve routes air and is not a lock; add an external rod lock or pilot-operated check valve for held loads. For strokes over 300mm, use side-load guides. The -S suffix enables CMSG/DMSG sensors.
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 SAUF32X80S-08B 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 cycles/sec) running on DC24V. Although the cylinder body rates to 1.0MPa, the assembled unit operates strictly within the valve's 0.15-0.8MPa window.
By default, the rod retracts when the coil is energised; you can reconfigure it to extend-when-energised by repositioning the valve. The 5/2 valve only routes air and does not lock the load; add an external rod lock or pilot-operated check valve to prevent drift on air loss.
