Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X500-06B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X500-06B is a genuine double-acting profile-type cylinder with a Ø40mm bore, 500mm 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 SAUF40X500-06B
The SAUF40X500-06B is a double-acting profile cylinder with a built-in AirTAC 4M210-06 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. This SKU lacks a magnet and cannot take a magnetic switch.
It features a 40mm bore, 500mm stroke, 1/4" cylinder port, and a 1/8" valve port. The integrated valve flows 14 mm2 (Cv 0.78) at up to 5 cycles/s. The coil is DC24V with terminal entry. The body rates to 1.0 MPa, but the assembled unit operates at 0.15-0.8 MPa. At 0.5 MPa it pushes 628 N and pulls 528 N. A safe working load is roughly 377 N, allowing a vertical lift of about 32 kg 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 (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 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 SAUF40X500-06B Is Used
Conveyor Diverter Gate
Uses the built-in 4M210-06 valve to actuate a 500mm diverter arm directly at the conveyor, eliminating long tubing runs back to a central manifold.
Decentralized Pallet Stop
Deploys a 40mm bore stop pin across a roller lane; the single DC24V coil signal simplifies control wiring in large automated storage systems.
Machine Tool Guard Door
Opens and closes a 500mm stroke safety guard using one coil signal, saving manifold space while providing 628 N push force at 0.5 MPa.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X500-06B the Right Choice?
Size by comparing the 40mm bore (628 N push @0.5 MPa) against the 32mm (402 N) and 50mm (982 N) neighbors. Confirm the DC24V terminal coil and 1/8" valve port. The cylinder body rates to 1.0 MPa, but the integrated valve limits the assembled unit to 0.15-0.8 MPa. Default action retracts the rod when energised; reposition the valve to extend when energised. The valve routes air and is not a lock; add an external rod lock or pilot-operated check valve to hold a load. 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 SAUF40X500-06B FAQ
It pushes 628 N and pulls 528 N at 0.5 MPa. The built-in valve is a 4M210-06 (1/8" port, Cv 0.78, 5 cycles/s max) with a DC24V terminal coil. Although the cylinder body rates to 1.0 MPa, the assembled unit operates strictly within 0.15-0.8 MPa.
The default action retracts the rod when the coil is energised. You can reconfigure it to extend when energised by repositioning the valve. Because this SKU lacks a magnet, it cannot accept magnetic switches.
