Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X200-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X200-08A is a genuine double-acting profile-type cylinder with a Ø40mm bore, 200mm stroke and a built-in 4M210-08 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 SAUF40X200-08A
The AirTAC SAUF40X200-08A is a double-acting profile cylinder featuring an integrated 4M210-08 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 cylinder of the same bore. This 40mm bore unit has a 1/4" cylinder port, an M12x1.25 rod thread, and 21mm adjustable cushions.
Operating within the valve's 0.15-0.8 MPa window, it delivers 628N push and 528N pull at 0.5 MPa. The built-in valve flows 16 mm2 (Cv 0.89) and handles up to 5 cycles per second. The AC220V terminal entry coil is IP65 rated with a 0.05s response. For sizing, the safe working load is roughly 377N (about 60% of the 0.5MPa push force), translating to a vertical lift capacity of approximately 32kg 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 (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 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 SAUF40X200-08A Is Used
Divert Gate Actuation
Drives a sorting diverter directly at the conveyor lane, using the built-in valve to switch instantly without routing tubing back to a central manifold.
Decentralized Clamp Station
Powers a standalone clamping fixture on a large welding table, where one AC220V signal actuates the clamp independently of neighboring stations.
Machine Door Operator
Opens and closes an equipment access panel using the integrated 4M210-08 valve, saving manifold space and simplifying the machine's pneumatic layout.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X200-08A the Right Choice?
Size by checking both neighboring bores: the 32mm bore yields 402N push at 0.5 MPa, while the 50mm bore provides 982N. This 40mm unit offers 628N push, so select it when your load sits near 377N. Confirm the AC220V terminal entry and PT thread match your supply. The rod retracts by default when energized, but you can reconfigure it to extend by repositioning the valve. Always size force within the 0.15-0.8 MPa valve range, not the 1.0 MPa cylinder body rating. Because this SKU lacks a magnet, it cannot take a magnetic switch. The valve routes air and does not function as a load lock; add an external rod lock or pilot-operated check valve for holding. For this 200mm stroke, ensure adequate side-load guidance.
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 SAUF40X200-08A FAQ
It generates 628N push and 528N pull at 0.5 MPa. The built-in valve is a 4M210-08 (1/4" port, Cv 0.89, 5 cycles/sec max) driven by an AC220V terminal coil. You must size the force within the valve's 0.15-0.8 MPa operating window, even though the cylinder body rates to 1.0 MPa.
Yes. The default action retracts the rod when the coil receives power, but you can reconfigure it to extend-when-energized simply by repositioning the built-in valve on the cap. This allows you to choose the fail-safe state for your application without extra parts.
