Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X200-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X200-08A is a genuine double-acting profile-type cylinder with a Ø32mm bore, 200mm 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 SAUF32X200-08A
The SAUF32X200-08A 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, and the 1/8" cylinder port pairs with a 1/4" valve port.
Operating strictly within the valve's 0.15-0.8 MPa window, it delivers 402 N push at 0.5 MPa. The integrated 4M210-08 valve provides 16 mm2 flow (Cv 0.89) and handles 5 cycles/sec. For sizing, expect a safe working load around 241 N, or a 20 kg vertical lift with a 2:1 margin. This terminal-entry AC220V SKU lacks a magnet, so it 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 SAUF32X200-08A Is Used
Decentralized Clamping
Ideal for a machining cell where each clamping station uses one coil signal to actuate independently, saving manifold space.
Inline Diverting
Mounts directly on a conveyor diverter arm. The built-in 4M210 valve eliminates tubing runs back to a central island.
Compact Part Ejection
Fits in tight machine frames for ejecting small parts. The profile barrel keeps the footprint minimal without remote valves.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X200-08A the Right Choice?
Size force within the 0.15-0.8 MPa valve range: this 32 mm bore pushes 402 N at 0.5 MPa, sitting between the 40 mm bore (628 N) and smaller actuators. The 200 mm stroke is well under the 1000 mm max standard and above the 50 mm minimum. Confirm the AC220V terminal entry and PT threads meet your control voltage. The rod retracts when energised but can be reconfigured to extend by repositioning the valve. Because this SKU has no magnet (-S), it cannot take a magnetic switch. The valve routes air but is not a load lock; add an external rod lock or pilot-operated check valve to hold a load. For this 200 mm stroke, standard guidance handles side loads, but always guide longer strokes over 300 mm.
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 SAUF32X200-08A FAQ
It delivers 402 N push and 345 N pull at 0.5 MPa, sized strictly within the built-in 4M210-08 valve's 0.15-0.8 MPa operating window. The 1/4" valve port provides 16 mm2 flow (Cv 0.89) and 5 cycles/sec. The coil is AC220V with terminal entry.
Yes, the default action retracts the rod when energised, but you can reconfigure it to extend by repositioning the valve. The valve only routes air; it is not a load lock. The piston will drift on air loss, so add an external rod lock or pilot-operated check valve for holding.
