Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X350S-10B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X350S-10B is a genuine double-acting profile-type cylinder with a Ø80mm bore, 350mm stroke and a built-in 4M310-10 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 SAUF80X350S-10B
The SAUF80X350S-10B is a double-acting profile-type cylinder with a built-in AirTAC 4M310 5-port 2-position 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. This 80mm bore unit features a 3/8" air port, M20x1.5 rod thread, and a 28mm adjustable cushion.
Operating within the valve's 0.15-0.8 MPa window, it delivers a push force of 2513 N at 0.5 MPa (4021 N at 0.8 MPa). The integrated 4M310-10 valve has a 3/8" port, Cv 1.68 flow, and cycles up to 4 times per second. The DC24V terminal coil is IP65 rated. For sizing, the safe working load is roughly 1508 N, translating to a 128 kg vertical lift capacity with a 2:1 margin. The -S suffix provides a piston magnet for CMSG/DMSG/EMSG switches.

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 (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 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 SAUF80X350S-10B Is Used
Decentralized Conveyor Diverters
Ideal for large conveyor systems where mounting a remote valve manifold is impractical. The built-in 4M310 valve lets each diverter operate independently from a single DC24V signal.
Independent Stacking Gates
Perfect for warehouse sorting lines needing one valve per actuator. The 80mm bore provides 2513 N push force at 0.5 MPa without requiring extensive pneumatic tubing runs back to a central manifold.
Machine Tool Loading Arms
Excellent for decentralized automation cells. The compact profile cylinder saves space while the integrated solenoid handles rapid part loading at up to 4 cycles per second.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X350S-10B the Right Choice?
When sizing, compare neighboring bores: the 63mm bore offers 1559 N push at 0.5 MPa, while the 100mm bore provides 3927 N. This 80mm bore delivers 2513 N push and 2268 N pull at 0.5 MPa. Always size force within the 0.15-0.8 MPa valve operating range, not 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 you can reposition the valve to extend on energization. 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 load lock; add an external rod lock or pilot-operated check valve to hold loads safely.
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 SAUF80X350S-10B FAQ
This model uses a 4M310-10 valve (3/8" port, Cv 1.68, max 4 cycles/sec) with a DC24V terminal coil. The 80mm bore generates 2513 N push and 2268 N pull at 0.5 MPa, reaching 4021 N at 0.8 MPa. Size force within the valve's 0.15-0.8 MPa operating window; do not use the cylinder body's 1.0 MPa rating for assembled operation.
No. The built-in 5/2 valve routes air but does not function as a load lock. If air is lost, the piston drifts and the 28mm cushion only decelerates near stroke end. For load holding, install an external rod lock or pilot-operated check valve. The default action retracts when energized, but you can reposition the valve to extend on energization.
