Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X400-06B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X400-06B is a genuine double-acting profile-type cylinder with a Ø50mm bore, 400mm 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 SAUF50X400-06B
The SAUF50X400-06B 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 unit of the same bore. This 50mm bore has a 1/4" cylinder port, an M16x1.5 rod thread, and 21mm adjustable cushions.
Operating within the valve's 0.15-0.8 MPa range, it delivers 982N push and 825N pull at 0.5 MPa. The integrated 4M210-06 valve has a 1/8" port, Cv 0.78 flow, and cycles up to 5 times per second. The DC24V coil offers IP65 protection with terminal entry. For sizing, the safe working load is roughly 589N (60% of the 0.5MPa push), translating to a 50kg vertical lift 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 SAUF50X400-06B Is Used
Decentralized Divert Gate
Actuates a sorting diverter directly on the conveyor frame using one DC24V signal, avoiding long tube runs back to a central manifold.
Independent Clamp Station
Provides 982N clamping force at a standalone workstation, freeing up manifold slots for other actuators on the main machine.
Remote Forming Pusher
Drives a 400mm push stroke in a forming cell where running individual air lines is costly, utilizing the built-in 4M210 valve.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X400-06B the Right Choice?
When sizing, compare neighbouring bores: a 40mm bore yields 628N push at 0.5MPa, while a 63mm bore provides 1559N. This 50mm bore sits comfortably between, delivering 982N push. Always size force within the 0.15-0.8 MPa valve window, not the 1.0 MPa cylinder body rating. Confirm the DC24V terminal entry matches your control signal. By default the rod retracts when energised; repositioning the valve changes this to extend-when-energised. Because this is a 400mm stroke, use external guides to prevent rod bending and side-load damage. The built-in valve routes air but does not lock the load; add an external rod lock or pilot-operated check valve for holding. This SKU lacks a magnet and cannot accept a sensor.
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 SAUF50X400-06B FAQ
It delivers 982N push and 825N pull at 0.5 MPa. The built-in valve is a 4M210-06 (1/8" port, Cv 0.78, 5 cycles/sec max) driven by a DC24V terminal-entry coil. You must size the force within the valve's 0.15-0.8 MPa operating window, even though the cylinder body rates to 1.0 MPa.
The valve routes air and does not lock the piston; on air loss the load drifts, so add an external rod lock or pilot check valve for holding. The default action retracts the rod when energised, but you can reposition the valve to extend-when-energised. This SKU has no magnet, so it cannot take a sensor.
