Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X160-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X160-08B is a genuine double-acting profile-type cylinder with a Ø40mm bore, 160mm 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 SAUF40X160-08B
The SAUF40X160-08B is a double-acting profile cylinder with a built-in AirTAC 4M210-08 5/2 solenoid valve on the cap. One DC24V coil signal drives the actuator, eliminating remote plumbing and saving a manifold slot. The extruded aluminum barrel is shorter than an ISO 15552 cylinder of the same bore. It uses a 1/4" cylinder port and a 1/4" valve port.
Size force strictly within the valve's 0.15-0.8 MPa operating window, even though the cylinder body rates to 1.0 MPa. At 0.5 MPa this 40mm bore delivers 628N push and 528N pull. The safe working load is roughly 377N (about 60% of the 0.5 MPa push force), yielding a vertical lift capacity of approximately 32kg with a 2:1 margin. The integrated valve flows 16mm2 (Cv 0.89) at up to 5 cycles per second, uses terminal entry, and pairs with PU tube 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 SAUF40X160-08B Is Used
Inline Diverter Gate
Decentralized sorting on a conveyor where the integrated valve eliminates long tubing runs back to a central manifold.
Independent Clamp Station
A single coil signal actuates this 40mm clamp on an assembly cell, freeing up manifold slots for other tools.
Component Pusher
Pushes parts into a machining fixture at up to 5 cycles per second without needing a remote 4M210 valve.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X160-08B the Right Choice?
Compare this 40mm bore (628N push at 0.5 MPa) against the 32mm bore (402N) or the 50mm bore (982N) to match your load. Confirm the DC24V terminal entry coil meets your electrical supply. The rod retracts when the coil energises; reposition the valve to switch to extend-when-energised. Because the built-in valve routes air rather than locking it, add an external rod lock or pilot-operated check valve if you must hold a load against pressure loss. Keep operating pressure between 0.15-0.8 MPa. For this 160mm stroke, guide the load to manage side-load forces. This SKU lacks a magnet (-S) and cannot accept a magnetic switch.
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 SAUF40X160-08B FAQ
It delivers 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/s max) with a DC24V terminal entry coil. Although the cylinder body rates to 1.0 MPa, the assembled unit operates strictly within 0.15-0.8 MPa.
No. The built-in 5/2 valve routes air but does not lock the piston. On pressure loss the rod drifts and the 21mm adjustable cushion only decelerates near stroke end. Install an external rod lock or pilot-operated check valve for load holding.
