Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X225S-06B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X225S-06B is a genuine double-acting profile-type cylinder with a Ø50mm bore, 225mm stroke and a built-in 4M210-06 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 SAUF50X225S-06B
The SAUF50X225S-06B 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 makes it shorter than an ISO 15552 cylinder of the same bore. The 1/4" cylinder port and M16x1.5 rod thread handle the 225 mm stroke.
The integrated 4M210-06 valve has a 1/8" port, 14 mm2 flow (Cv 0.78), and cycles up to 5 times per second. The DC24V coil offers IP65 protection with terminal entry. Size force within the 0.15-0.8 MPa valve window, as the cylinder body rates to 1.0 MPa but the valve limits the assembly. At 0.5 MPa it pushes 982 N and pulls 825 N, giving a safe working load of about 589 N or a 50 kg vertical lift with a 2:1 margin. The S suffix means a piston magnet is present 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 (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 SAUF50X225S-06B Is Used
Modular Assembly Cells
Ideal for decentralized clamping where one coil signal per station saves manifold space and simplifies PU tube routing.
Diverter Gates
Self-switching actuation handles package sorting at up to 5 cycles per second without remote valve banks.
Component Insertion
The compact profile fits tight machine frames, using the built-in magnet for position confirmation during pressing.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X225S-06B the Right Choice?
When sizing, compare the 50 mm bore against neighbours: a 40 mm bore pushes 628 N while a 63 mm bore pushes 1559 N at 0.5 MPa. The 50 mm bore yields 982 N push and 825 N pull at 0.5 MPa, with a maximum push of 1570 N at the 0.8 MPa assembled limit. Confirm the DC24V coil and terminal entry suit your control system. By default the rod retracts when energised, but repositioning the valve changes it to extend-when-energised. The valve routes air and is not a load lock; add an external rod lock or pilot-operated check valve to hold a load. For this 225 mm 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 SAUF50X225S-06B FAQ
It pushes 982 N and pulls 825 N at 0.5 MPa, reaching 1570 N at 0.8 MPa. The built-in 4M210-06 valve has a 1/8" port, Cv 0.78, and runs on DC24V. Although the cylinder body rates to 1.0 MPa, the assembled unit must operate within the 0.15-0.8 MPa valve 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 removes the need for a separate remote valve.
