Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X75S-06A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X75S-06A is a genuine double-acting profile-type cylinder with a Ø40mm bore, 75mm 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 SAUF40X75S-06A
The SAUF40X75S-06A is a double-acting profile cylinder with a built-in AirTAC 4M210 5/2 solenoid valve on the cap. One AC220V 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 has a 1/4" cylinder port, a 1/8" valve port, and a piston magnet for CMSG/DMSG/EMSG switches.
Operating within the valve's 0.15-0.8 MPa window, it delivers 628N push and 528N pull at 0.5 MPa. The 4M210-06 valve flows 14 mm2 (Cv 0.78) at up to 5 cycles/s. For sizing, the safe working load is roughly 377N, and vertical lift capacity is about 32kg with a 2:1 margin. The terminal-entry coil is IP65 rated with a 0.05s response. PU tube size is Ø8xØ5.

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 SAUF40X75S-06A Is Used
Decentralized Clamping
Ideal for distributed machining cells where running separate valve lines is costly; one AC220V signal actuates the clamp directly at the fixture.
Inline Diverting
Perfect for conveyor sorting gates that switch up to 5 cycles per second, using the integrated 4M210 valve to save manifold space.
Package Pushing
Provides reliable 628N push at 0.5 MPa for ejecting cartons off packaging lines without needing a centralized remote valve bank.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X75S-06A the Right Choice?
Size this 40mm bore against its neighbours: a 32mm bore yields 402N push, while a 50mm bore yields 982N push at 0.5 MPa. This model provides 628N push, making the safe working load approximately 377N. Confirm your coil is AC220V with terminal entry. The default action retracts the rod when energised, but you can reconfigure it to extend by repositioning the valve. Always size force within the 0.15-0.8 MPa valve range, not the 1.0 MPa cylinder body rating. The integrated valve routes air but does not lock the load; for drop prevention add an external rod lock or pilot-operated check valve. For this 75mm stroke, side-load guides are not strictly required, but ensure adequate guidance for any stroke exceeding 300mm.
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 SAUF40X75S-06A FAQ
It generates 628N push and 528N pull at 0.5 MPa. The built-in valve is a 4M210-06 (1/8" port, Cv 0.78, 5 cycles/s). The coil is AC220V with terminal entry. Although the cylinder body rates to 1.0 MPa, the assembled unit must operate within the valve's 0.15-0.8 MPa window.
Yes. The default factory setting retracts the rod when the coil is energised. You can change this to extend-when-energised by physically repositioning the built-in valve on the cap. Note that the valve only routes air; it does not hold the load without air pressure.
