Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X450S-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X450S-08B is a genuine double-acting profile-type cylinder with a Ø32mm bore, 450mm 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 SAUF32X450S-08B
The SAUF32X450S-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 32mm bore has a 1/8" cylinder port, an M10x1.25 rod thread, and 21mm adjustable cushions. The S suffix means a piston magnet is present for CMSG/DMSG/EMSG switches.
Operating in the 0.15-0.8 MPa valve window, it delivers 402N push and 345N pull at 0.5 MPa. The integrated valve flows 16 mm2 (Cv 0.89) at 1/4", cycling up to 5 times per second. The DC24V terminal coil is IP65 rated. For sizing, the safe working load is roughly 241N, and vertical lift capacity is about 20kg 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 (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 SAUF32X450S-08B Is Used
Diverter Gate Actuation
Decentralized conveyor sorting where the integrated 4M210-08 valve triggers a 450mm stroke to push parcels, saving manifold space and tubing runs.
Component Pusher Station
Ideal for standalone machine cells; the DC24V coil directly switches this 32mm actuator to push parts into a machining fixture without remote plumbing.
Packaging Flap Control
One-signal operation drives a 450mm reach to fold carton flaps, utilizing the built-in magnet for end-of-stroke CMSG sensor confirmation.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X450S-08B the Right Choice?
When sizing, compare neighbouring bores: a 40mm bore yields 628N push at 0.5 MPa versus 402N here. Confirm the DC24V terminal coil and PT thread suit your control system. The default action retracts the rod when energised; reposition the valve to extend on signal. Size force strictly within the 0.15-0.8 MPa valve range, not the 1.0 MPa cylinder body rating. The valve routes air and does not lock the load; add an external rod lock or pilot-operated check valve to hold position. For the 450mm stroke, use external guides to prevent rod bending and side-load 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 SAUF32X450S-08B FAQ
It delivers 402N push and 345N 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 flows 16 mm2 (Cv 0.89) with a DC24V terminal coil. The cylinder body rates to 1.0 MPa but the assembled unit must run at 0.8 MPa or less.
No, the 5/2 valve routes air and is not a load lock; the piston drifts on air loss. For position holding you must add an external rod lock or pilot-operated check valve. Note the default action retracts when energised, but you can reposition the valve to extend on signal.
