Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X150S-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X150S-08A is a genuine double-acting profile-type cylinder with a Ø50mm bore, 150mm 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 SAUF50X150S-08A
The SAUF50X150S-08A is a double-acting profile-type cylinder with a built-in AirTAC 4M210-08 5/2 solenoid valve mounted directly 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 cylinder of the same bore. This 50mm bore unit has a 1/4" cylinder port and a 1/4" valve port, delivering a push force of 982N at 0.5MPa. The integrated valve operates at 0.15-0.8 MPa, so size within that window rather than the 1.0 MPa cylinder body rating.
The built-in valve provides a flow of 16 mm2 (Cv 0.89) and handles up to 5 cycles per second. It uses an AC220V terminal entry coil (IP65, class B) and includes a piston magnet for CMSG/DMSG/EMSG switches. For sizing, the safe working load is roughly 589N (about 60% of the 0.5MPa push force), and it can vertically lift around 50kg with a 2:1 margin. 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 (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa | 1374 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 SAUF50X150S-08A Is Used
Decentralized Clamping
Ideal for large machining cells where each clamping station uses one coil signal to actuate independently, saving manifold space and tubing runs.
Inline Diverters
Perfect for conveyor sorting gates that require rapid localized switching, handling up to 5 cycles per second without a remote valve bank.
Package Pushers
Suits compact packaging lines needing a 50kg vertical lift capability, using the built-in valve to minimize control cabinet wiring.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X150S-08A the Right Choice?
Size this 50mm bore against the neighboring 40mm and 63mm options. At 0.5MPa the 50mm delivers 982N push and 825N pull, sitting between the 40mm (628N) and 63mm (1559N). Confirm your coil matches the AC220V terminal entry specification. The default action retracts the rod when energized, but you can reconfigure it to extend-when-energised by repositioning the valve. Always size force within the 0.15-0.8 MPa valve operating range. The valve routes air and is not a lock; for load holding on air loss, add an external rod lock or pilot-operated check valve. For this 150mm stroke, ensure adequate side-load guidance.
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 SAUF50X150S-08A FAQ
It delivers 982N push and 825N pull at 0.5MPa. The built-in valve is a 4M210-08 (1/4" port, Cv 0.89, 5/2 solenoid) running on AC220V. Although the cylinder body rates to 1.0MPa, the assembled unit must operate within the valve's 0.15-0.8MPa window.
Yes. The default factory setting retracts the rod when the coil is energized. You can change it to extend-when-energised simply by repositioning the built-in valve. This self-switching design means no remote valve is needed.
