Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X900S-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X900S-08B 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-08B
The SAUF80X900S-08B 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 makes it shorter than an ISO 15552 unit of the same bore. It features a 900 mm stroke with a built-in piston magnet for CMSG/DMSG/EMSG switches.
Operating at DC24V via terminal entry, the integrated valve provides 25 mm2 flow (Cv 1.4) and handles up to 4 cycles per second. The cylinder body rates to 1.0 MPa, but you must size force within the valve's 0.15-0.8 MPa working window. At 0.5 MPa it pushes 2513 N and pulls 2268 N. For reliable sizing, the safe working load is roughly 1508 N, yielding a vertical lift capacity of about 128 kg with a 2:1 margin.

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 SAUF80X900S-08B Is Used
Long-Stroke Diversion
Drives a 900 mm sorting arm on a conveyor line directly from one coil signal, removing the need to route long tubing back to a central manifold.
Decentralized Pallet Handling
Positions pallet stops independently at multiple machine zones, saving manifold slots while providing 2513 N of push force at 0.5 MPa.
Automated Press Feed
Actuates a 900 mm material feed mechanism using the integrated 4M310-08 valve, simplifying installation on large machinery.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X900S-08B the Right Choice?
When sizing this 80 mm bore actuator against its neighbours, note the 63 mm bore pushes 1559 N while the 100 mm bore pushes 3927 N at 0.5 MPa. This model delivers a 2513 N push and 2268 N pull at 0.5 MPa, sized strictly within the 0.15-0.8 MPa valve limit. Confirm the DC24V coil and terminal entry meet your control requirements. By default the rod retracts when the coil is energised, but you can reconfigure it to extend by repositioning the valve. Because the 900 mm stroke exceeds 300 mm, use an external guide to prevent rod bending and side-load damage. The built-in valve routes air and does not function as a load lock; add an external rod lock or pilot-operated check valve to hold a load securely.
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-08B FAQ
It pushes 2513 N and pulls 2268 N at 0.5 MPa. The built-in valve is a 4M310-08 5/2 solenoid with 1/4" port, Cv 1.4, and runs on DC24V. Although the cylinder body rates to 1.0 MPa, the assembled unit must operate within the valve's 0.15-0.8 MPa range.
Yes. The default action retracts the rod when the coil is energised, but you can reconfigure it to extend-when-energised simply by repositioning the valve. This self-switching design means no remote valve is required.
