Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X200-06A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X200-06A 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 SAUF40X200-06A
The SAUF40X200-06A is a double-acting profile cylinder with a built-in AirTAC 4M210 5/2 solenoid valve on the cap. One coil signal drives the actuator directly, 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 1/4" cylinder port, an M12x1.25 rod thread, and 21mm adjustable cushions.
Operating within the 0.15-0.8 MPa valve window, this bore pushes 628 N and pulls 528 N at 0.5 MPa. The integrated 4M210-06 valve has a 1/8" port, 14 mm2 flow (Cv 0.78), and cycles up to 5 times per second. The AC220V terminal-entry coil is IP65 rated. For sizing, a safe working load is roughly 377 N, capable of a 32 kg vertical lift 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 SAUF40X200-06A Is Used
Diverter Gate Actuation
Drives a decentralized sorting flap directly at the conveyor lane without running long tubing back to a central manifold.
Compact Clamping Station
Holds a workpiece in a tight machining cell where a separate valve would consume valuable space and a manifold slot.
Product Pusher
Ejects items from a packaging line using a single AC220V signal, simplifying wiring and maximizing cycle rates.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X200-06A the Right Choice?
When sizing, compare neighbouring bores: a 32mm bore pushes 402 N while a 50mm bore pushes 982 N at 0.5 MPa. This 40mm bore provides 628 N push and 528 N pull at 0.5 MPa. Confirm the AC220V terminal entry matches your supply. The default action retracts the rod when energised, but you can reposition the valve to extend on signal. Size forces 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 hold load on pressure loss; add an external rod lock or pilot-operated check valve for suspended loads. For this 200mm stroke, ensure 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 SAUF40X200-06A FAQ
It delivers 628 N push and 528 N pull at 0.5 MPa. The built-in valve is a 4M210-06 (1/8" port, Cv 0.78, 5 cycles/sec max) driven by an AC220V terminal-entry coil. Although the cylinder body rates to 1.0 MPa, you must size the assembled unit within the 0.15-0.8 MPa valve operating window.
By default the rod retracts when the coil is energised, but you can reconfigure it to extend by repositioning the valve. The valve only routes air; it does not lock the piston. If air is lost the load will drift, so install an external rod lock or pilot-operated check valve for suspended loads.
