Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X500S-06A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X500S-06A 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 SAUF40X500S-06A
The SAUF40X500S-06A is a double-acting profile cylinder with a built-in AirTAC 4M210-06 5/2 solenoid valve on the cap. One AC220V coil signal drives the actuator, eliminating remote plumbing and saving a manifold slot. The 40mm bore delivers 628N push and 528N pull at 0.5MPa, operating safely within the valve's 0.15-0.8MPa window. The extruded aluminum barrel is shorter than an ISO 15552 unit of the same bore.
This model includes a piston magnet for CMSG/DMSG/EMSG switches. The integrated valve flows 14mm2 (Cv 0.78) at 1/8" with a 5 cycle/s limit. The cylinder port is 1/4". For sizing, the safe working load is roughly 377N (60% of the 0.5MPa push), and vertical lift is about 32kg 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 SAUF40X500S-06A Is Used
Decentralized Conveyor Divert
Mounts directly at the divert gate on a long conveyor line. One AC220V signal actuates the 500mm stroke without routing tubes back to a central manifold.
Independent Pusher Station
Ideal for a standalone pallet pusher in a warehouse zone. The built-in 4M210-06 valve removes the need for a local valve island, simplifying installation.
Machine Tool Loading
Loads parts into a machining center. The 40mm bore provides 628N push at 0.5MPa, and the piston magnet supports position confirmation via reed switches.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X500S-06A the Right Choice?
When sizing, compare neighbouring bores: a 32mm bore yields 402N push while a 50mm bore yields 982N at 0.5MPa. This 40mm bore provides 628N push. Confirm the coil is AC220V with terminal entry and PT threads. The rod retracts when energised but can be reconfigured to extend by repositioning the valve. Size force strictly within the 0.15-0.8MPa valve range, not the 1.0MPa cylinder body rating. The valve routes air and is not a load 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 SAUF40X500S-06A FAQ
It delivers 628N push and 528N pull at 0.5MPa. The built-in valve is a 4M210-06 (1/8" port, Cv 0.78, 5 cycles/s) driven by an AC220V terminal-entry coil. Although the cylinder body rates to 1.0MPa, the assembled unit must operate within the valve's 0.15-0.8MPa range.
By default the rod retracts when energised. You can reconfigure it to extend-when-energised simply by repositioning the built-in valve. Because the valve only routes air, use an external rod lock or pilot-operated check valve if you need to hold a load during air loss.
