Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X500S-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X500S-08B is a genuine double-acting profile-type cylinder with a Ø32mm bore, 500mm 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 SAUF32X500S-08B
The SAUF32X500S-08B is a double-acting profile-type cylinder with a built-in AirTAC 4M210-08 5/2 solenoid valve on the cap. One DC24V 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. It includes a piston magnet for CMSG/DMSG/EMSG switches.
The 32mm bore delivers 402N push and 345N pull at 0.5MPa, operating within the valve's 0.15-0.8MPa window. The 1/4" ported valve flows 16mm2 (Cv 0.89) at up to 5 cycles/s. Computed buyer insight: safe working load is roughly 241N (60% of the 402N figure), yielding a 20kg vertical lift capacity with a 2:1 margin. The cylinder port is 1/8".

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 SAUF32X500S-08B Is Used
Decentralized Forming Press
Ideal for a large press where running a single DC24V signal to each actuator saves tubing and eliminates a central valve manifold.
Inline Divert Gate
A 500mm stroke divert gate that switches itself at up to 5 cycles/s, removing the need for remote pneumatic plumbing across the frame.
Vertical Lift Station
Lifts up to 20kg with a 2:1 margin using the built-in 4M210-08 valve, perfect for independent lift stations in a large distribution machine.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X500S-08B the Right Choice?
Size both ways: this 32mm bore pushes 402N at 0.5MPa, so step up to a 40mm bore for 628N if marginal, or down to a smaller profile if the load is lighter. Confirm the DC24V terminal entry and PT threads match your supply. The default action retracts when energised; reposition the valve to extend-when-energised. Size force within the 0.15-0.8MPa valve limit, not the 1.0MPa cylinder body rating. The valve routes air and is not a lock—add an external rod lock or pilot-operated check valve to hold loads. For the 500mm 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 SAUF32X500S-08B FAQ
It pushes 402N and pulls 345N at 0.5MPa. The built-in 4M210-08 valve has a 1/4" port, flows 16mm2 (Cv 0.89), and runs on DC24V. Although the cylinder body rates to 1.0MPa, the assembled unit operates at 0.15-0.8MPa.
The default action retracts the rod when the coil is energised. You can reconfigure it to extend-when-energised by repositioning the built-in valve. The valve only routes air, so add an external rod lock if you need to hold the load without air.
