Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X125-06A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X125-06A is a genuine double-acting profile-type cylinder with a Ø40mm bore, 125mm 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 SAUF40X125-06A
The AirTAC SAUF40X125-06A is a double-acting profile cylinder with a built-in 4M210-06 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 makes it shorter than an ISO 15552 unit of the same bore. This 40mm bore delivers 628N push and 528N pull at 0.5MPa, operating within the 0.15-0.8MPa valve window.
The integrated valve handles 1/8" ports with a 14mm2 flow (Cv 0.78) and cycles up to 5 times per second. It uses an AC220V terminal-entry coil rated IP65. The cylinder body itself rates to 1.0MPa, but the assembled unit is limited by the valve to 0.8MPa. Based on the 0.5MPa push force, the safe working load is roughly 377N, capable of a 32kg 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 SAUF40X125-06A Is Used
Inline Diverter Gate
Switches a conveyor sorting flap directly at the line, using the built-in valve to eliminate long tube runs back to a central manifold.
Independent Clamp Station
Holds a workpiece in a multi-station fixture where one coil signal per clamp simplifies control wiring and saves manifold slots.
Decentralized Press Unit
Performs a short stamping operation inside a large machine cell, relying on the 4M210 valve for fast 5Hz local actuation.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X125-06A the Right Choice?
Size this 40mm bore against its neighbours: the 32mm bore yields 402N push at 0.5MPa, while the 50mm bore yields 982N. This model provides 628N push and 528N pull at 0.5MPa. Confirm the AC220V terminal entry matches your supply. The rod retracts when the coil energises; repositioning the valve changes it to extend-when-energised. Always size force within the 0.15-0.8MPa valve range, never the 1.0MPa cylinder rating. The valve routes air and does not lock the load; add an external rod lock or pilot-operated check valve to hold position. For this 125mm stroke side-load is minimal, but strokes over 300mm require a guide. This SKU lacks a magnet and cannot take a sensor.
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 SAUF40X125-06A FAQ
It delivers 628N push and 528N pull at 0.5MPa. 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 1.0MPa, the assembled unit operates strictly within 0.15-0.8MPa.
Yes. The default action retracts the rod on energisation, but you can reconfigure it to extend-when-energised simply by repositioning the valve. This self-switching design means no remote valve is needed.
