Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X900S-06B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X900S-06B is a genuine double-acting profile-type cylinder with a Ø40mm bore, 900mm 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 SAUF40X900S-06B
The SAUF40X900S-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 40mm bore delivers 628N push and 528N pull at 0.5MPa, with a 1/4" cylinder port and an M12x1.25 rod thread.
The integrated valve has a 1/8" port, 14mm2 flow (Cv 0.78), and switches up to 5 cycles/sec. It runs on DC24V via terminal entry with IP65 protection. The cylinder body rates to 1.0MPa, but size force within the valve's 0.15-0.8MPa window. The -S suffix provides a piston magnet for CMSG/DMSG/EMSG sensors. Computed buyer insight: safe working load is roughly 377N (60% of the 628N push at 0.5MPa), yielding a vertical lift capacity of 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 SAUF40X900S-06B Is Used
Decentralized Conveyor Divert
Mounts directly at the divert gate on a long conveyor line. The built-in 4M210-06 valve switches locally from one DC24V signal, removing long tube runs back to a central manifold.
Vertical Package Lift
Lifts packages up to 32kg using the 900mm stroke. The self-contained valve simplifies electrical wiring in high-density sorting hubs, requiring only a single coil signal per actuator.
Machine Guard Gate
Drives a 900mm safety gate on a large machine. The integrated valve saves manifold space while the piston magnet supports CMSG/DMSG position sensing for safe closure confirmation.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X900S-06B the Right Choice?
When sizing, compare both ways: the neighboring 32mm bore yields 402N push at 0.5MPa, while the 50mm bore yields 982N. This 40mm bore provides 628N push and 528N pull at 0.5MPa. Confirm the DC24V terminal entry and PT threads match your supply. The default action retracts the rod when energized, but you can reconfigure it to extend by repositioning the valve. Always size within the 0.15-0.8MPa valve range, not the 1.0MPa cylinder body limit. The valve routes air and is not a load lock; for held loads add an external rod lock or pilot-operated check valve. At 900mm stroke, prevent rod bending by adding external guides to manage side loads.
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 SAUF40X900S-06B 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/sec max) running on DC24V. Although the cylinder body rates to 1.0MPa, the assembled unit must operate within the valve's 0.15-0.8MPa window.
By default the rod retracts when the coil is energized, but you can reconfigure it to extend by repositioning the valve. The valve only routes air; it is not a load lock. On air loss the piston drifts, so add an external rod lock or pilot-operated check valve for load holding.
