Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X800-06B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X800-06B is a genuine double-acting profile-type cylinder with a Ø40mm bore, 800mm 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 SAUF40X800-06B
The SAUF40X800-06B is a double-acting profile 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 makes it shorter than an ISO 15552 cylinder of the same bore.
It features a 40mm bore, 800mm 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. Operating on DC24V with terminal entry, it runs within the 0.15-0.8 MPa valve window. The 628N push force at 0.5MPa yields a safe working load of 377N and a 32kg vertical lift capacity.

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 SAUF40X800-06B Is Used
Decentralized Conveyor Divert
Ideal for a remote divert gate on a long conveyor. The integrated valve eliminates long tube runs back to a central manifold.
Independent Stack Pusher
Drives a single pusher in a large warehouse layout. One DC24V signal cycles the 4M210 valve directly at the actuator.
Remote Machine Gate
Perfect for opening a safety guard on a sprawling machine. Saves manifold slots and simplifies installation.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X800-06B the Right Choice?
Size by comparing the 40mm bore (628N push @0.5MPa) against the 32mm (402N) and 50mm (982N) options. This DC24V terminal-entry model has no -S suffix, so it cannot accept a magnetic switch. The rod retracts when energised but can be reconfigured to extend by repositioning the valve. Always size force within the 0.15-0.8 MPa valve range, 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 this 800mm stroke, use external guides to prevent rod bending and 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 SAUF40X800-06B 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/s) running on DC24V. Size force within the 0.15-0.8 MPa valve operating window, not the 1.0MPa cylinder body limit.
The built-in valve routes air but does not lock the piston; add a pilot-operated check valve for holding. By default the rod retracts when the coil is energised, but you can reposition the valve to extend when energised.
