Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X200-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X200-08B 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 SAUF40X200-08B
The SAUF40X200-08B is a double-acting profile cylinder with a built-in AirTAC 4M210-08 5/2 solenoid valve on the cap. One coil signal drives the rod, eliminating remote plumbing and saving a manifold slot. The extruded aluminum barrel is shorter than an ISO 15552 cylinder of the same bore. It has a 1/4" cylinder port, a 16 mm rod, and an M12x1.25 rod thread.
Operating in the 0.15-0.8 MPa valve window, it delivers 628 N push at 0.5 MPa. A computed buyer insight gives a safe working load of about 377 N, or a 32 kg vertical lift with a 2:1 margin. The DC24V terminal coil offers IP65 protection and the valve flows at Cv 0.89 with a 5 cycle/s limit. This SKU lacks a magnet, so it cannot take a magnetic switch.

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 SAUF40X200-08B Is Used
Inline Diverter Gate
Decentralized sorting on a conveyor where one coil signal flips a gate, saving tubing back to a central manifold.
Component Clamping Station
Independent clamping on an assembly cell, using the built-in valve for rapid 5 cycle/s actuation without a manifold slot.
Carton Flap Folder
Single-actuator flap folding on a packing line, driven directly by the DC24V coil for simple wiring and compact profile.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X200-08B the Right Choice?
Size by checking both neighbours: the 32 mm bore yields 402 N push at 0.5 MPa, while the 50 mm bore yields 982 N. This 40 mm bore provides 628 N push and 528 N pull at 0.5 MPa. Keep pressure within the 0.15-0.8 MPa valve range, never the 1.0 MPa cylinder body rating. The DC24V terminal entry is fixed. The rod retracts when energised but you can reposition the valve to extend on signal. For this 200 mm stroke, guide the load to manage side-load. The valve routes air but does not lock; add an external rod lock or pilot-operated check valve to hold a load.
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 SAUF40X200-08B FAQ
It pushes 628 N and pulls 528 N at 0.5 MPa. The built-in valve is a 4M210-08 5/2 solenoid with 1/4" port, Cv 0.89 flow, and a 5 cycle/s limit. The DC24V terminal coil runs on 3.0 W with IP65 protection. Size force within the 0.15-0.8 MPa valve operating window, not the 1.0 MPa cylinder body rating.
No remote valve is needed; the integrated valve switches the cylinder from one coil signal. The valve only routes air and is not a load lock. On air loss the piston drifts, so add an external rod lock or pilot-operated check valve for holding. The rod retracts when energised but you can reposition the valve to extend instead.
