Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X300S-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X300S-08A is a genuine double-acting profile-type cylinder with a Ø80mm bore, 300mm 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 SAUF80X300S-08A
The SAUF80X300S-08A is a double-acting profile cylinder with a built-in AirTAC 4M310-08 5/2 solenoid valve on the cap. One AC220V coil signal drives the actuator, eliminating remote plumbing and saving a manifold slot. The extruded aluminum barrel is shorter than an ISO 15552 unit of the same bore. The bore dictates a 3/8" cylinder port and M20x1.5 rod thread, while the valve port is 1/4".
Size force strictly within the valve's 0.15-0.8 MPa window, not the 1.0 MPa cylinder body rating. At 0.5 MPa it delivers 2513 N push and 2268 N pull. The 4M310-08 valve flows 25 mm2 (Cv 1.4) at up to 4 cycles/s. Computed buyer insight: safe working load is roughly 1508 N (60% of the 0.5 MPa push), enabling 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)

| 0.7 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 SAUF80X300S-08A Is Used
Divert Gate Actuation
Decentralized diverters on a packaging line benefit from one coil signal per gate, removing long tube runs back to a central manifold.
Pallet Stopper Control
Independent stopper stations on a roller conveyor use the built-in 4M310 valve to switch locally, saving manifold slots and installation time.
Machine Tool Clamping
Individual clamping points on a large machining center operate autonomously via the integrated valve, simplifying pneumatic plumbing.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X300S-08A the Right Choice?
Compare neighbours: the 63 mm bore yields 1559 N push at 0.5 MPa, while the 100 mm bore reaches 3927 N. This 80 mm bore provides 2513 N push, making it ideal for mid-range loads. Confirm the AC220V terminal entry and PT threads before ordering. Default action retracts the rod when energised; reposition the valve to extend on energisation. The 300 mm stroke requires external guiding to prevent rod bending under side-load. Remember the assembled unit operates at 0.15-0.8 MPa. The valve only routes air; 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 SAUF80X300S-08A FAQ
It pushes 2513 N and pulls 2268 N at 0.5 MPa. The built-in valve is a 4M310-08 (1/4" port, Cv 1.4, 25 mm2 flow, max 4 cycles/s). The coil is AC220V with terminal entry. Size force within the valve's 0.15-0.8 MPa operating window, as the assembled unit cannot run at the 1.0 MPa cylinder body rating.
Yes. The default action retracts the rod when energised, but you can reposition the valve to extend on energisation. The valve routes air and is not a load lock; the cylinder will drift on air loss. Install an external rod lock or pilot-operated check valve for secure load holding.
