Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X350-06A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X350-06A is a genuine double-acting profile-type cylinder with a Ø50mm bore, 350mm 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 SAUF50X350-06A
The SAUF50X350-06A is a double-acting profile-type 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 makes it shorter than an ISO 15552 cylinder of the same bore. It features a 50mm bore, 1/4" cylinder port, and a 350mm stroke.
Operating within the 0.15-0.8 MPa valve window, it delivers 982N push force at 0.5 MPa. The integrated valve provides 14 mm2 flow (Cv 0.78) and handles up to 5 cycles per second. The AC220V terminal-entry coil is IP65 rated. Since this SKU lacks a magnet, it cannot accept magnetic switches. Based on the 0.5 MPa push force, the safe working load is roughly 589N, yielding a vertical lift capacity of about 50kg 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 SAUF50X350-06A Is Used
Diverter Gate Actuation
Decentralized sorting lines use this self-switching cylinder to push diverter gates directly at the conveyor, cutting tubing runs to a central manifold.
Packaging Machine Pusher
Ideal for remote pack-off stations where installing a separate valve bank is impractical, relying on the built-in 4M210 valve for rapid 5 cycle/sec operation.
Modular Machine Tooling
Saves manifold slots on large assembly platforms by driving individual tooling heads with a single AC220V coil signal per actuator.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X350-06A the Right Choice?
When sizing, compare neighboring bores: a 40mm bore gives 628N push while a 63mm bore yields 1559N at 0.5 MPa. This 50mm bore provides 982N push and 825N pull. Confirm the AC220V terminal entry matches your control voltage. The default action retracts the rod when energized, but you can reconfigure it to extend by repositioning the valve. Always size force within the 0.15-0.8 MPa valve range, not the 1.0 MPa cylinder body rating. Because the 350mm 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 SAUF50X350-06A FAQ
It generates 982N push and 825N pull at 0.5 MPa. The built-in valve is a 4M210-06 (1/8" port, Cv 0.78, 14 mm2 flow) with an AC220V terminal-entry coil. Although the cylinder body rates to 1.0 MPa, the assembled unit must operate within the 0.15-0.8 MPa valve window.
By default, the rod retracts when the coil is energized, but you can switch it to extend-when-energized by repositioning the valve. The valve only routes air, so it is not a load lock; the piston will drift on air loss. Add an external rod lock or pilot-operated check valve for load holding.
