Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X50-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X50-08B is a genuine double-acting profile-type cylinder with a Ø32mm bore, 50mm 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 SAUF32X50-08B
The SAUF32X50-08B 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 has a 1/8 inch cylinder port, a 12mm rod, and 21mm adjustable cushions.
Operating in the 0.15-0.8 MPa valve window, it delivers 402N push at 0.5 MPa. The integrated valve is a 4M210-08 with 1/4 inch port, Cv 0.89, and 5 cycles/sec. Computed insight: safe working load is 241N, allowing a 20kg vertical lift. This DC24V terminal entry unit lacks a magnet and cannot take 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 SAUF32X50-08B Is Used
Decentralized Clamping
Ideal for a clamping station where the built-in valve provides local actuation without running tubes back to a central manifold.
Inline Diverter Gate
Perfect for a conveyor diverter arm needing one coil signal per motion, saving manifold space and simplifying wiring.
Independent Pick & Place
Suits a small robotic gripper where decentralized control reduces cycle time by eliminating long air lines from remote valves.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X50-08B the Right Choice?
Size between the 32mm bore (402N push @0.5MPa) and the larger 40mm bore (628N push). This SKU uses a DC24V terminal entry and lacks a magnet, so it cannot accept magnetic switches. Default action retracts the rod when energised; reposition the valve to extend on signal. Size force within the 0.15-0.8 MPa valve range, not the 1.0 MPa cylinder rating. The valve routes air and is not a lock; add an external rod lock or pilot-operated check valve to hold loads. At 50mm stroke, side-load guiding is minimal.
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 SAUF32X50-08B FAQ
It delivers 402N push and 345N pull at 0.5 MPa. The built-in valve is a 4M210-08 (1/4 inch port, Cv 0.89, 5 cycles/sec) running on DC24V. The cylinder body rates to 1.0 MPa, but you must size force within the valve's 0.15-0.8 MPa operating window.
No, the 5/2 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. Also, this specific SKU lacks a magnet and cannot take magnetic switches.
