Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X350-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X350-08A is a genuine double-acting profile-type cylinder with a Ø40mm bore, 350mm 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 SAUF40X350-08A
The SAUF40X350-08A is a double-acting profile cylinder with a built-in AirTAC 4M210-08 5/2 solenoid valve on the cap. One AC220V coil signal drives the actuator, eliminating remote plumbing and saving a manifold slot in decentralized installations. The extruded aluminum barrel makes it shorter than an ISO 15552 unit of the same bore. This SKU uses terminal entry and PT threads.
It delivers 628N push and 528N pull at 0.5MPa, operating safely within the valve's 0.15-0.8MPa range despite the 1.0MPa cylinder body rating. The 1/4" valve port yields a 16mm2 flow (Cv 0.89) at up to 5 cycles/sec. Computed buyer insight: safe working load is roughly 377N (60% of the 0.5MPa push), allowing a 32kg vertical lift with a 2:1 margin. The bore's air port is 1/4". Without a magnet, this version 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 SAUF40X350-08A Is Used
Decentralized Clamping
Ideal for multi-station clamping where each actuator switches itself via one coil signal, saving tubing and manifold space.
Independent Diverters
Powers individual conveyor diverting gates without running long air lines back to a central valve island.
Localized Pick-and-Place
Drives compact 350mm stroke transfer arms directly at the work cell, simplifying machine wiring.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X350-08A the Right Choice?
Size by comparing neighbors: bore 32 gives 402N push while bore 50 offers 982N at 0.5MPa, so this 40mm bore fits medium loads. Confirm the AC220V terminal entry matches your control scheme. The rod retracts when energised but can be reconfigured to extend by repositioning the valve. Always size force within the 0.15-0.8MPa valve window. The valve routes air and is not a lock; add an external rod lock or pilot-operated check valve to hold loads. For the 350mm stroke, use external guides to prevent rod bending and side-load wear.
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 SAUF40X350-08A FAQ
It pushes 628N and pulls 528N at 0.5MPa. The built-in valve is a 4M210-08 (1/4" port, Cv 0.89, 5 cycles/sec) running on AC220V. Although the cylinder body rates to 1.0MPa, the assembled unit operates at 0.15-0.8MPa.
Yes. The default action retracts the rod when energised, but you can reposition the valve to make it extend instead. Because this SKU lacks a magnet (-S), it cannot take magnetic sensors.
