Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X500-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X500-08A is a genuine double-acting profile-type cylinder with a Ø50mm bore, 500mm 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 SAUF50X500-08A
The SAUF50X500-08A is a double-acting profile cylinder with a built-in AirTAC 4M210-08 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 a standard ISO 15552 unit of the same bore. It features a 50mm bore, 500mm stroke, 1/4" cylinder port, and an M16x1.5 rod thread.
Operating within the valve's 0.15-0.8 MPa range, it delivers 982 N push force at 0.5 MPa. The 1/4" valve port provides 16 mm2 flow (Cv 0.89) and handles up to 5 cycles per second. The AC220V terminal entry coil is IP65 rated with a 0.05 s response. Based on the 0.5 MPa push force, the safe working load is roughly 589 N, and it can vertically lift about 50 kg with a 2:1 margin. Note this SKU lacks the S magnet, so it cannot accept a magnetic switch.

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 SAUF50X500-08A Is Used
Decentralized Diverters
Drives sorting gates directly on the conveyor frame without routing long air lines back to a central manifold.
Independent Lift Stations
Powers individual vertical lifting pins at packing stations, switching locally from one AC220V signal.
Remote Machine Guards
Actuates safety doors on large equipment where running individual pneumatic lines would be costly.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X500-08A the Right Choice?
Size force between the 0.15-0.8 MPa valve window: this 50mm bore pushes 982 N and pulls 825 N at 0.5 MPa. If you need less force, the 40mm bore offers 628 N push; for more power, the 63mm bore provides 1559 N at the same pressure. Confirm the AC220V terminal coil voltage matches your supply. The rod retracts by default when energized, but you can reconfigure it to extend by repositioning the valve. Because the 500mm stroke exceeds 300mm, add external guides to prevent rod bending and side loads. The valve only routes air, so for load holding on pressure loss, install an external rod lock or pilot-operated check valve.
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 SAUF50X500-08A FAQ
It pushes 982 N and pulls 825 N at 0.5 MPa. The built-in valve is a 4M210-08 5/2 solenoid with 1/4" port, 16 mm2 flow (Cv 0.89), and 5 cycles/sec max. The AC220V coil runs on an IP65 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.
No, the built-in valve only routes air and is not a load lock, so the piston drifts without pressure. Add an external rod lock or pilot-operated check valve to hold a load. By default the rod retracts when the coil is energized, but you can reconfigure it to extend by repositioning the valve.
