Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X200S-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X200S-08A is a genuine double-acting profile-type cylinder with a Ø80mm bore, 200mm stroke and a built-in 4M310-08 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 SAUF80X200S-08A
The SAUF80X200S-08A is a double-acting profile cylinder with a built-in AirTAC 4M310 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. The bore carries a 3/8" air port, a Ø25 mm rod, and M20x1.5 rod-end thread.
Operating within the valve's 0.15-0.8 MPa window, it delivers a 2513 N push force at 0.5 MPa. The integrated valve handles 1/4" porting with a 25 mm2 flow (Cv 1.4) and cycles up to 4 times per second. The AC220V terminal-entry coil is IP65 rated. Based on the 0.5 MPa push figure, the safe working load is roughly 1508 N, translating to a 128 kg vertical lift with a 2:1 margin. The -S suffix denotes 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)

|---|---|---|
| 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 SAUF80X200S-08A Is Used
Divert Gate Actuation
Uses one coil signal to swing a heavy diverter on a packaging line, saving manifold space and simplifying tubing.
Decentralized Pallet Stop
Mounts directly on a pallet conveyor stand. The integrated 4M310 valve handles the 80 mm bore without remote plumbing.
Machine Tool Clamp
Provides 2513 N push force at 0.5 MPa to secure parts, with the built-in magnet allowing position confirmation.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X200S-08A the Right Choice?
Size by force and neighbours: the 80 mm bore gives 2513 N push at 0.5 MPa, sitting between the 63 mm (1559 N) and 100 mm (3927 N) options. Confirm the AC220V terminal entry and 1/4" valve port fit your supply. Size all force calculations within the 0.15-0.8 MPa valve range, never the 1.0 MPa cylinder body rating. The rod retracts when the coil is energised; reposition the valve to switch to extend-when-energised. Because the valve only routes air, add an external rod lock or pilot-operated check valve to hold a load. For this 200 mm stroke, guide the load to manage 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 SAUF80X200S-08A FAQ
It delivers 2513 N push and 2268 N pull at 0.5 MPa. The built-in valve is a 4M310-08 (1/4" port, Cv 1.4, 25 mm2 flow) running on AC220V. 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 energised, but you can reposition the valve on the cap to make it extend-when-energised. This self-switching design means no remote valve is needed.
