Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X900S-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X900S-08A is a genuine double-acting profile-type cylinder with a Ø80mm bore, 900mm 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 SAUF80X900S-08A
The SAUF80X900S-08A is a double-acting profile 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. The extruded aluminum barrel is shorter than an ISO 15552 cylinder of the same bore. It features a 900 mm stroke, a Ø25 mm rod with an M20x1.5 thread, and a 3/8" cylinder port.
Operating within the valve's 0.15-0.8 MPa window, it generates 2513 N push and 2268 N pull at 0.5 MPa. The 1/4" valve port flows 25 mm2 (Cv 1.4) at up to 4 cycles per second. The AC220V terminal coil is IP65 rated with a 0.05 s response. Based on the 0.5 MPa push force, the safe working load is roughly 1508 N, translating to a 128 kg vertical lift 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)

| 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 SAUF80X900S-08A Is Used
Decentralized Conveyor Divert
Mounts directly at the divert station to push packages, needing only one AC220V signal and a Ø10xØ6.5 PU tube supply without a central manifold.
Long-Stroke Machine Guard
Uses the 900 mm stroke to open large safety doors on a machine cell, relying on the compact profile and integrated 4M310-08 valve to save cabinet space.
Vertical Material Lift
Lifts up to 128 kg with a 2:1 safety margin at 0.5 MPa, ideal for decentralized pallet handling where a separate remote valve would add unwanted tubing.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X900S-08A the Right Choice?
Size force between the 63 mm bore (1559 N push @0.5 MPa) and 100 mm bore (3927 N push @0.5 MPa) alternatives, keeping the assembled unit within the 0.15-0.8 MPa valve limit rather than the 1.0 MPa cylinder body rating. Confirm the AC220V terminal entry and PT threads meet your control specs. The default action retracts the rod when energised, but repositioning the valve changes it to extend-when-energised. Because the 900 mm stroke exceeds 300 mm, use external guides to prevent rod bending and side-load wear. 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 on air loss.
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 SAUF80X900S-08A FAQ
It generates 2513 N push and 2268 N pull at 0.5 MPa, reaching 4021 N push at the 0.8 MPa maximum. The built-in valve is a 4M310-08 (1/4" port, Cv 1.4, 4 cycles/s) driven by an AC220V terminal coil. Size the force within the valve's 0.15-0.8 MPa operating window, not the 1.0 MPa cylinder body rating.
No, the built-in 5/2 valve only routes air and is not a lock; the piston will drift on air loss. For vertical holding you must add an external rod lock or pilot-operated check valve. The default action retracts when energised, but you can reposition the valve to extend-when-energised.
