Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X900S-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X900S-08A is a genuine double-acting profile-type cylinder with a Ø63mm 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 SAUF63X900S-08A
The SAUF63X900S-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 cylinder of the same bore. This 63mm bore unit has a 3/8 inch air port, an M16x1.5 rod thread, and a 900mm stroke.
It operates within the valve's 0.15-0.8 MPa window, delivering a 1559N push force at 0.5 MPa. The integrated 4M310-08 valve features a 1/4 inch port, Cv 1.4 flow, and switches up to 4 cycles per second. The AC220V terminal entry coil is IP65 rated. For sizing, the safe working load is roughly 935N, and it can vertically lift about 79kg with a 2:1 margin. The S suffix denotes a piston magnet for CMSG/DMSG/EMSG sensors.

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 (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1402 N |
| 0.7 MPa | 2182 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 SAUF63X900S-08A Is Used
Long-Stroke Diversion
Decentralized sorting gates on a conveyor belt. The 900mm stroke pushes large cartons to adjacent lanes without running long tubing back to a central manifold.
Vertical Material Lift
Elevating goods between warehouse levels. The built-in 4M310 valve responds in under 0.05s, providing rapid localized lifting for tote handling systems.
Machine Guard Gate
Operating safety guards on large automated machinery. One AC220V signal drives the 63mm bore actuator, simplifying electrical control wiring across the factory floor.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X900S-08A the Right Choice?
When sizing, compare both neighboring bores: the 50mm bore offers 982N push at 0.5 MPa, while the 80mm bore provides 2513N. This 63mm unit delivers 1559N push and 1402N pull at 0.5 MPa. Always size force within the built-in valve's 0.15-0.8 MPa operating range, never the 1.0 MPa cylinder body rating. Confirm your coil needs AC220V power with terminal entry. By default the rod retracts when energized, but you can reposition the valve to extend on signal. Because the 900mm stroke exceeds 300mm, use an external guide to prevent rod bending and side-load wear. The valve only routes air; for load holding on air loss, add an external rod lock or pilot-operated check valve.
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 SAUF63X900S-08A FAQ
It delivers 1559N push and 1402N pull at 0.5 MPa, reaching 2494N push at 0.8 MPa. The built-in valve is a 4M310-08 (5/2 solenoid) with a 1/4 inch port and Cv 1.4 flow. The coil is AC220V with terminal entry. You must size force within the valve's 0.15-0.8 MPa operating window, not the 1.0 MPa cylinder body rating.
No. The built-in valve routes air but is not a load lock. If air is lost, the piston will drift and the adjustable cushions only decelerate near stroke end. For vertical load holding, install an external rod lock or pilot-operated check valve. The default action retracts the rod when energized, but you can reposition the valve to extend on signal.
