Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X900S-06B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X900S-06B is a genuine double-acting profile-type cylinder with a Ø50mm 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 SAUF50X900S-06B
The SAUF50X900S-06B is a double-acting profile-type cylinder with a built-in AirTAC 4M210-06 5/2 solenoid valve on the cap. One DC24V 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 50mm bore unit has a 1/4" cylinder port, an M16x1.5 rod thread, and a 900mm stroke with a piston magnet for CMSG/DMSG/EMSG switches.
The integrated valve delivers a 1/8" port, 14.0 mm2 flow (Cv 0.78), and runs at up to 5 cycles/sec. Size force within the valve's 0.15-0.8 MPa window, where this bore pushes 982 N at 0.5 MPa. A practical computed insight: safe working load is roughly 589 N (about 60% of the 0.5 MPa push force), and vertical lift capacity is about 50 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 (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa | 1374 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 SAUF50X900S-06B Is Used
Decentralized Conveyor Divert
Mounts directly at the divert station. The integrated 4M210-06 valve switches the 900mm stroke via one DC24V signal without tubing back to a central manifold.
Long-Reach Pusher Array
Ideal for spaced-out pusher stations in a warehouse. Each actuator self-switches, saving manifold slots and simplifying the 1/4" cylinder port plumbing.
Independent Gating Station
Drives a 50mm bore parts gate independently. The built-in magnet supports CMSG/DMSG/EMSG switches for position feedback at the end of the 900mm travel.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X900S-06B the Right Choice?
When sizing, compare both ways: the neighboring 40mm bore pushes 628 N while the 63mm bore pushes 1559 N at 0.5 MPa. This 50mm bore provides 982 N push and 825 N pull at 0.5 MPa. Always size within the built-in valve's 0.15-0.8 MPa operating window, never the 1.0 MPa cylinder body rating. Confirm the DC24V terminal entry and PT thread meet your electrical specs. The default action retracts the rod when energized, but repositioning the valve changes it to extend-when-energized. Because the 900mm stroke exceeds 300mm, use an external guide to prevent rod bending and side-load wear. The valve routes air and is not a lock; for load holding on air loss, add an external rod lock or pilot-operated check valve.
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 SAUF50X900S-06B FAQ
It pushes 982 N and pulls 825 N at 0.5 MPa. The built-in valve is a 4M210-06 (1/8" port, Cv 0.78, 5 cycles/sec max) running on a DC24V terminal-entry coil. You must size force within the valve's 0.15-0.8 MPa operating window, not the 1.0 MPa cylinder body rating.
Yes. The default action retracts the rod when energized, but you can reconfigure it to extend-when-energized simply by repositioning the built-in valve. This self-switching design means no remote valve is needed, though the valve only routes air and does not lock the load.
