Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X250-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X250-08A is a genuine double-acting profile-type cylinder with a Ø80mm bore, 250mm 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 SAUF80X250-08A
The SAUF80X250-08A is an extruded aluminum profile-type double-acting cylinder with a built-in AirTAC 4M310-08 5/2 solenoid valve on the cap. One coil signal drives the actuator, eliminating remote plumbing and saving a manifold slot. It is shorter than an ISO 15552 cylinder of the same bore and mounts with AirTAC SC series accessories.
Operating strictly within the valve's 0.15-0.8 MPa window, it delivers a 2513 N push at 0.5 MPa. The 1/4" port valve flows 25 mm2 (Cv 1.4) at up to 4 cycles/s. The AC220V terminal entry coil is IP65 rated. For sizing, a safe working load is roughly 1508 N, translating to a 128 kg vertical lift with a 2:1 margin. Note the 3/8" cylinder port and Ø10xØ6.5 PU tube.

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 SAUF80X250-08A Is Used
Decentralized Diverter
Sort packages directly on the line using one coil signal per actuator, bypassing a central valve manifold.
Machine Clamp Station
Clamp workpieces independently with the integrated 4M310 valve, reducing tubing complexity across the cell.
Vertical Lift Gate
Actuate access gates without remote plumbing, leveraging the 128 kg vertical lift capacity safely.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X250-08A the Right Choice?
Size against the 63 mm bore (1559 N push @0.5 MPa) or the 100 mm bore (3927 N push @0.5 MPa). This 80 mm bore provides 2513 N push at 0.5 MPa. Confirm the AC220V terminal entry and PT threads. The rod retracts when energised but can be reconfigured to extend by repositioning the valve. Because the 4M310 valve routes air, it is not a load lock; add an external rod lock or pilot-operated check valve to hold loads. For this 250 mm stroke, use a guide to manage side loads. This SKU lacks a magnet and cannot take a sensor.
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 SAUF80X250-08A FAQ
It pushes 2513 N and pulls 2268 N at 0.5 MPa, reaching 4021 N at 0.8 MPa. The built-in valve is a 4M310-08 (1/4" port, Cv 1.4, 25 mm2 flow, max 4 cycles/s). The cylinder body rates to 1.0 MPa, but the assembled unit must operate in the 0.15-0.8 MPa valve window. The coil is AC220V.
The 5/2 valve routes air and is not a load lock; the piston drifts on air loss, so add an external rod lock or pilot-operated check valve to hold a load. By default the rod retracts when the coil is energised, but you can reposition the valve to make it extend when energised.
