Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X225S-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X225S-08B is a genuine double-acting profile-type cylinder with a Ø32mm 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 SAUF32X225S-08B
The SAUF32X225S-08B 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. The S suffix means a piston magnet is present for CMSG/DMSG/EMSG switches.
Operating in the 0.15-0.8 MPa valve window, this 32 mm bore delivers 402 N push and 345 N pull at 0.5 MPa. The integrated valve has a 1/4" port, 16 mm2 flow (Cv 0.89), and handles 5 cycles/sec. Computed buyer insight: safe working load is roughly 241 N (60% of the 0.5 MPa push), with a vertical lift capacity of about 20 kg at a 2:1 margin. The cylinder port is 1/8" and the rod thread is M10x1.25.

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 SAUF32X225S-08B Is Used
Decentralized Clamping
Ideal for a clamping station where one coil signal per actuator eliminates long tubing runs back to a central manifold.
Inline Diverting
Perfect for a divert gate on a conveyor, using the built-in valve to switch the 32 mm bore rapidly without extra plumbing.
Compact Sorting
Fits tight sorting machinery where the shorter profile body and integrated 4M210 valve save valuable assembly space.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X225S-08B the Right Choice?
Size by checking both neighboring bores: the 40 mm bore raises push to 628 N at 0.5 MPa, while the 32 mm bore offers 402 N. This DC24V terminal entry coil (IP65) can be reconfigured from retract-when-energised to extend-when-energised by repositioning the valve. Always size force within the 0.15-0.8 MPa valve range, not the 1.0 MPa cylinder body rating. The built-in valve routes air but does not lock the piston; add an external rod lock or pilot-operated check valve to hold loads. For this 225 mm stroke, provide side-load guidance to prevent rod 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 SAUF32X225S-08B FAQ
It delivers 402 N push and 345 N pull at 0.5 MPa using a built-in 4M210-08 valve (1/4" port, Cv 0.89, 5 cycles/sec). The DC24V terminal entry coil runs the assembled unit at 0.15-0.8 MPa, despite the cylinder body rating of 1.0 MPa.
Yes, the default retract-when-energised action can be switched to extend-when-energised by repositioning the valve. The valve only routes air; it is not a lock, so you must add an external rod lock or pilot-operated check valve to hold a load on air loss.
