Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X500-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X500-08B 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 SAUF32X500-08B
The SAUF32X500-08B is a double-acting profile-type cylinder with a built-in AirTAC 4M210 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 cylinder of the same bore. It features a 12mm rod, M10x1.25 rod-end thread, and 1/8" cylinder ports.
Operating within the 0.15-0.8 MPa valve window, it delivers 402 N push force at 0.5 MPa. The integrated 4M210-08 valve has a 1/4" port, Cv 0.89, and handles 5 cycles/sec. The DC24V terminal coil offers IP65 protection. For sizing, the safe working load is roughly 241 N, and vertical lift capacity is about 20 kg with a 2:1 margin. Note this SKU lacks a magnet, so it cannot accept 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 (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 SAUF32X500-08B Is Used
Diverter Gate Actuation
Drives a decentralized sorting flap directly at the conveyor lane, removing the need to run long tubing back to a central valve manifold.
Independent Clamp Station
Powers a single clamping head in a multi-station fixture, allowing independent cycle timing via the built-in 4M210 valve without manifold constraints.
Remote Pusher Mechanism
Actuates a 500mm stroke pusher on a storage rack, saving installation time by switching locally from one DC24V signal instead of remote plumbing.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X500-08B the Right Choice?
When sizing, compare neighboring bores: a 40mm bore yields 628 N push at 0.5 MPa versus 402 N here. Confirm the DC24V terminal coil and PT thread match your supply. The rod retracts by default when energized but can be reconfigured to extend by repositioning the valve. Always size force within the 0.15-0.8 MPa valve limit, not the 1.0 MPa cylinder body rating. This 500mm stroke requires external guides to prevent rod bending under side loads. The built-in valve routes air but does not lock the load; add an external rod lock or pilot-operated check valve for holding.
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 SAUF32X500-08B 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). The DC24V coil operates at 5 cycles/sec. Although the cylinder body rates to 1.0 MPa, the assembled unit must operate within the 0.15-0.8 MPa valve window.
No, the built-in valve routes air and is not a load lock. The piston drifts on air loss, and the 21mm cushions only decelerate near stroke end. For load holding, install an external rod lock or pilot-operated check valve. Also, this non-magnet SKU cannot take a sensor.
