Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X350-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X350-08A is a genuine double-acting profile-type cylinder with a Ø50mm bore, 350mm stroke and a built-in 4M210-08 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 SAUF50X350-08A
The SAUF50X350-08A is an extruded aluminum profile cylinder, shorter than an ISO 15552 unit of the same bore, with a built-in AirTAC 4M210-08 5/2 solenoid valve on the cap. One coil signal drives the cylinder, eliminating remote plumbing and saving a manifold slot. It uses a 1/4" valve port, delivering a 16 mm2 flow (Cv 0.89) at up to 5 cycles per second.
Operating within the 0.15-0.8 MPa valve window, it provides 982 N push force at 0.5 MPa. The computed safe working load is roughly 589 N, allowing a vertical lift of about 50 kg with a 2:1 margin. This terminal-entry AC220V coil (IP65) retracts the rod by default. Without a magnet suffix, this SKU cannot accept a magnetic switch.

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 SAUF50X350-08A Is Used
Diverter Gate Actuation
Decentralized sorting line diverter where one coil signal per gate saves manifold space and simplifies tubing across the conveyor.
Clamp Station Control
Independent machining clamp that switches itself directly, eliminating the need for a remote valve bank near the cutting zone.
Package Pusher Unit
Logistics line pusher using the 350 mm stroke to transfer parcels, relying on the integrated valve for fast local response.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X350-08A the Right Choice?
Size force between the 40 mm bore (628 N push) and 63 mm bore (1559 N push) at 0.5 MPa. The 50 mm bore gives 982 N push and 825 N pull at 0.5 MPa, safely inside the 0.15-0.8 MPa valve range. Confirm the AC220V terminal entry meets your supply. The rod retracts when energised but can be reconfigured to extend by repositioning the valve. The built-in valve routes air and is not a load lock; add an external rod lock or pilot-operated check valve to hold a load. For this 350 mm stroke, use an external guide 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 SAUF50X350-08A FAQ
It generates 982 N push at 0.5 MPa using the integrated 4M210-08 valve (1/4" port, Cv 0.89, 5 cycles/s max). The AC220V terminal-entry coil operates at 0.15-0.8 MPa. Never size the assembled unit above 0.8 MPa, even though the cylinder body rates to 1.0 MPa.
Yes. The default action retracts the rod upon energising, but you can reconfigure it to extend-when-energised simply by repositioning the valve. This self-switching design removes the need for any remote valve.
