Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X100-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X100-08A is a genuine double-acting profile-type cylinder with a Ø40mm bore, 100mm 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 SAUF40X100-08A
The SAUF40X100-08A 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 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 uses a 1/4" air port and a M12x1.25 rod thread.
Operating within the 0.15-0.8 MPa valve window, it delivers 628N push force at 0.5 MPa. The integrated valve flows 16 mm2 (Cv 0.89) and handles 5 cycles/sec. The AC220V terminal-entry coil is IP65 rated. For sizing, the safe working load is roughly 377N, and vertical lift capacity is about 32kg with a 2:1 margin. Note this SKU lacks a magnet and cannot accept a sensor.

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 SAUF40X100-08A Is Used
Conveyor Diverter Gate
Decentralized diverter on a packaging line. The built-in valve means one AC220V signal flips the gate without running long tubing back to a central manifold.
Component Clamp Station
Ideal for a machining cell clamp. The 4M210-08 valve switches the 628N clamping force directly at the cap, saving manifold space and install time.
Modular Machine Frame
Perfect for actuating stops on a modular assembly frame. Each cylinder switches itself independently, drastically reducing pneumatic plumbing complexity.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X100-08A the Right Choice?
Size by comparing the 50mm bore (982N push @0.5 MPa) and the 32mm bore (402N push @0.5 MPa) against your load. This 40mm bore yields 628N push. 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. Always size force within the 0.15-0.8 MPa valve range, not the 1.0 MPa cylinder body rating. The valve routes air and is not a lock; add an external rod lock or pilot-operated check valve to hold loads. For this 100mm stroke, side-load is minimal, but always guide the rod for longer strokes.
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 SAUF40X100-08A 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-entry coil. You must size the force within the 0.15-0.8 MPa operating window of the assembled valve, not the 1.0 MPa cylinder body rating.
No, the 5/2 valve only routes air and is not a load lock; the piston will drift on air loss. Add an external rod lock or pilot-operated check valve for holding. Also, this specific SKU lacks a magnet (-S), so it cannot accept a magnetic reed switch.
