Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X225-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X225-08B is a genuine double-acting profile-type cylinder with a Ø50mm bore, 225mm 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 SAUF50X225-08B
The AirTAC SAUF50X225-08B is a double-acting profile cylinder with a built-in 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 makes it shorter than a standard cylinder of the same bore. It features a 50mm bore, 225mm stroke, 1/4" cylinder port, and an M16x1.5 rod thread.
Operating strictly within the 0.15-0.8 MPa valve window, it delivers 982N push and 825N pull at 0.5 MPa. A computed buyer insight: safe working load is roughly 589N, and vertical lift is about 50kg with a 2:1 margin. The DC24V terminal coil offers IP65 protection and uses a PU tube sized at Ø8xØ5. Without a magnet suffix, this SKU cannot take a magnetic switch.

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 SAUF50X225-08B Is Used
Diverter Gate Actuation
Drives a localized diverter arm directly at the conveyor lane, using the built-in valve to switch instantly without routing tubing back to a central manifold.
Decentralized Pallet Stop
Deploys a pallet stop block on a roller line; the integrated 4M210-08 valve saves manifold space and simplifies installation across long transfer lines.
Independent Clamping Station
Clamps parts at a standalone machining cell with one coil signal, removing the need for a dedicated remote valve bank nearby.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X225-08B the Right Choice?
Size force by comparing neighbor bores: the 40mm bore yields 628N push while the 63mm bore yields 1559N at 0.5 MPa. This 50mm bore provides 982N push, making it ideal for medium loads. Confirm the DC24V terminal entry and PT thread match your control system. The default action retracts the rod when energized, but you can reposition the valve to extend on signal. Always size within the 0.15-0.8 MPa valve range, never the 1.0 MPa cylinder body rating. Because the valve only routes air, add an external rod lock or pilot-operated check valve for load holding. For this 225mm stroke, ensure side-load guidance to prevent uneven wear.
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 SAUF50X225-08B FAQ
It delivers 982N push and 825N pull at 0.5 MPa, sized strictly within the 0.15-0.8 MPa valve window. The built-in valve is a 4M210-08 (1/4" port, Cv 0.89, 16mm2 flow) with a max frequency of 5 cycles/s. The coil is DC24V with terminal entry.
Yes, the default action retracts the rod on signal, but you can reposition the valve to extend when energized. The valve only routes air and is not a lock; the piston drifts on air loss, so add an external rod lock or pilot-operated check valve for load holding.
