Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X50S-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X50S-08A 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 SAUF32X50S-08A
The SAUF32X50S-08A is a double-acting profile cylinder with a built-in AirTAC 4M 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 cylinder of the same bore. This 32 mm bore unit has a 1/8" cylinder port, an M10x1.25 rod thread, and a 21 mm adjustable cushion.
It runs an integrated 4M210-08 valve (1/4" port, Cv 0.89, 5 cycles/s) on AC220V terminal entry. The cylinder body rates to 1.0 MPa, but size force within the valve's 0.15-0.8 MPa window. At 0.5 MPa it pushes 402 N, giving a safe working load of roughly 241 N and a 20 kg vertical lift capacity with a 2:1 margin. The -S suffix means a piston magnet is included for CMSG/DMSG/EMSG switches.

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 SAUF32X50S-08A Is Used
Decentralized Clamping
Ideal for a machining cell where each clamping station uses one coil signal to actuate independently, saving manifold space and tubing runs.
Inline Diverter Gate
Perfect for a conveyor diverter that needs a compact 32 mm bore and integrated 4M210 valve to switch packages without a remote valve bank.
Component Pusher
Suits an assembly line pusher where the built-in valve allows local control, pushing parts with 402 N force at 0.5 MPa directly at the workstation.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X50S-08A the Right Choice?
Size by checking both neighbours: the 40 mm bore offers 628 N push at 0.5 MPa if you need more force, while this 32 mm bore provides 402 N. Confirm the AC220V terminal entry matches your control voltage. The rod retracts when the coil is energised, but you can reconfigure it to extend-when-energised by repositioning the valve. Always size within the 0.15-0.8 MPa valve operating range, not the 1.0 MPa cylinder body rating. The built-in valve routes air and is not a load lock; for held loads add an external rod lock or pilot-operated check valve. For this 50 mm stroke side-load is minimal, but for strokes 300 mm or longer use a guide to prevent rod 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 SAUF32X50S-08A FAQ
It generates 402 N push and 345 N pull at 0.5 MPa. The built-in valve is a 4M210-08 (1/4" port, Cv 0.89) running on AC220V. Although the cylinder body rates to 1.0 MPa, you must size force within the valve's 0.15-0.8 MPa operating window.
By default the rod retracts when the coil is energised. You can reconfigure it to extend-when-energised simply by repositioning the built-in valve. This self-switching design means no remote valve is needed.
