Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X200S-06A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X200S-06A is a genuine double-acting profile-type cylinder with a Ø40mm bore, 200mm stroke and a built-in 4M210-06 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 SAUF40X200S-06A
The SAUF40X200S-06A is a double-acting profile cylinder with a built-in AirTAC 4M210-06 5/2 solenoid valve on the cap. One AC220V coil signal drives the actuator, eliminating remote plumbing and saving a manifold slot. The extruded aluminum barrel is shorter than an ISO 15552 unit of the same bore. This 40mm bore has a 1/4" cylinder port, a 1/8" valve port, and a 200mm stroke. The -S suffix means a piston magnet is present for CMSG/DMSG/EMSG switches.
Operating within the 0.15-0.8 MPa valve window, it delivers 628N push and 528N pull at 0.5 MPa. The 4M210-06 valve flows 14 mm2 (Cv 0.78) at up to 5 cycles/sec. For sizing, the safe working load is roughly 377N (about 60% of the 0.5 MPa push force), and it can vertically lift around 32kg with a 2:1 safety margin. The coil uses terminal entry, PT threads, and PU tube sized at Ø8xØ5.

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 SAUF40X200S-06A Is Used
Decentralized Clamping
Ideal for a machining cell where each clamping station uses one coil signal, avoiding a central valve manifold.
Inline Divert Gate
Perfect for a divert gate on a conveyor line, saving tubing and simplifying installation by mounting the valve directly on the cap.
Package Stopper
Serves as a localized package stopper in a high-speed sorting hub, operating at up to 5 cycles per second.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X200S-06A the Right Choice?
When sizing, compare neighbouring bores: a 32mm bore yields 402N push at 0.5 MPa, while a 50mm bore yields 982N. This 40mm bore provides 628N push, making the 377N safe working load a solid target. Confirm your coil is AC220V with terminal entry. By default the rod retracts when energised; you can reconfigure it to extend-when-energised 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 the built-in valve only routes air, add an external rod lock or pilot-operated check valve if you need to hold a load. 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 SAUF40X200S-06A FAQ
It pushes 628N and pulls 528N at 0.5 MPa. The built-in valve is a 4M210-06 (1/8" port, Cv 0.78, 5 cycles/sec) driven by an AC220V terminal-entry coil. You must size the force within the 0.15-0.8 MPa valve operating window, even though the cylinder body rates to 1.0 MPa.
Yes. The default action retracts the rod when energised, but you can reconfigure it to extend-when-energised simply by repositioning the valve. Remember the valve only routes air; it is not a load lock, so use an external rod lock for holding.
