Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X100-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X100-08A is a genuine double-acting profile-type cylinder with a Ø50mm bore, 100mm 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 SAUF50X100-08A
The SAUF50X100-08A 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 has a 1/4" cylinder port, an M16x1.5 rod thread, and 21mm adjustable cushions.
Operating strictly within the valve's 0.15-0.8 MPa window, this bore pushes 982 N at 0.5 MPa. The 1/4" valve port yields a 16 mm2 flow (Cv 0.89) and handles 5 cycles/sec. The AC220V terminal coil is IP65 rated. For sizing, the safe working load is roughly 589 N, and it can vertically lift about 50 kg 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 (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa | 1374 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 SAUF50X100-08A Is Used
Decentralized Clamping
Ideal for a machining cell where each clamping station uses one coil signal, saving manifold space and tubing runs.
Inline Diverters
Perfect for a conveyor diverter gate that needs independent actuation without routing air lines back to a central manifold.
Package Stops
Suits a packaging line stopper requiring a 50 kg vertical lift capacity, operating at 5 cycles per second.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X100-08A the Right Choice?
Size force between the 0.15-0.8 MPa valve limits: this 50mm bore pushes 982 N at 0.5 MPa. If you need less force, the 40mm bore pushes 628 N; for more power, the 63mm bore pushes 1559 N. Confirm the AC220V terminal entry and PT threads suit your control panel. The rod retracts when the coil is energised but can be reconfigured to extend by repositioning the valve. Because the valve only routes air, add an external rod lock or pilot-operated check valve to hold a load. This 100mm stroke is well below the 300mm threshold requiring side-load guidance. Note that without the -S suffix, this SKU cannot accept a magnetic switch.
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 SAUF50X100-08A FAQ
It pushes 982 N and pulls 825 N at 0.5 MPa. The built-in valve is a 4M210-08 (1/4" port, Cv 0.89, 5 cycles/sec) with an AC220V terminal coil. Although the cylinder body rates to 1.0 MPa, the assembled unit must operate within the valve's 0.15-0.8 MPa window.
By default, the rod retracts when the coil is energised. You can reconfigure it to extend-when-energised by repositioning the valve. The valve routes air and is not a load lock, so you must add an external rod lock or pilot-operated check valve to prevent drift.
