Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X200S-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X200S-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 SAUF40X200S-08A
The SAUF40X200S-08A is a double-acting profile cylinder with a built-in AirTAC 4M210-08 5/2 solenoid valve on the cap. One AC220V coil signal drives the actuator directly, 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, an M12x1.25 rod thread, and a 200mm stroke with a piston magnet for CMSG/DMSG/EMSG switches.
Operating strictly within the valve's 0.15-0.8 MPa window, it delivers 628N push and 528N pull at 0.5 MPa. The 1/4" valve port yields a 16mm2 flow (Cv 0.89) and supports up to 5 cycles per second. For sizing, the safe working load is roughly 377N, and it can vertically lift about 32kg with a 2:1 margin. The terminal entry coil is IP65 rated with a 0.05s response time.

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-08A Is Used
Diverter Gate Control
Decentralized routing on a conveyor where one coil signal per gate saves manifold space and simplifies tubing runs.
Independent Clamping Station
A standalone clamping actuator on a large fixture, switching itself locally via the built-in 4M210 valve without a central manifold.
Inline Carton Sealing
Space-saving sealing jaw actuation that leverages the compact profile barrel and integrated valve for fast 5 cycle/sec operation.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X200S-08A the Right Choice?
Size this 40mm bore against its neighbors: the 32mm bore yields 402N push at 0.5 MPa, while the 50mm bore provides 982N. This model provides 628N push at 0.5 MPa, peaking at 1005N at the 0.8 MPa assembled limit. Confirm the AC220V terminal entry and PT threads suit your control panel. Default action retracts the rod when energized, but you can reposition the valve to extend on signal. The valve only routes air; it cannot hold a load on pressure loss, so add an external rod lock or pilot-operated check valve for vertical loads. Because the 200mm stroke exceeds 300mm, ensure external side-load guidance to prevent rod binding.
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-08A FAQ
It delivers 628N push and 528N pull at 0.5 MPa, reaching 1005N push at 0.8 MPa. The built-in valve is a 4M210-08 5/2 solenoid with a 1/4" port, 16mm2 flow (Cv 0.89), and a 5 cycle/sec max frequency. 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.
By default, the rod retracts when the coil is energized. You can reconfigure it to extend when energized simply by repositioning the built-in valve. This self-switching design means no remote valve is needed, saving tubing and a manifold slot.
