Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X200-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X200-08A is a genuine double-acting profile-type cylinder with a Ø50mm bore, 200mm 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 SAUF50X200-08A
The SAUF50X200-08A 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 cylinder directly, eliminating remote plumbing and saving a manifold slot. The extruded aluminum barrel makes it shorter than an ISO 15552 cylinder of the same bore. It features a 1/4" cylinder port, an M16x1.5 rod thread, and 21mm adjustable cushions.
Operating within the 0.15-0.8 MPa valve window, it delivers 982 N push force at 0.5 MPa. A practical computed insight: your safe working load is roughly 589 N (60% of the 0.5 MPa push), allowing a vertical lift of about 50 kg with a 2:1 margin. The integrated valve provides 16 mm2 flow (Cv 0.89) at up to 5 cycles per second. This AC220V terminal-entry coil is IP65 rated. Note this SKU lacks the S suffix, 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 SAUF50X200-08A Is Used
Decentralized Conveyor Divert
Ideal for a remote divert gate on a long conveyor. One AC220V signal actuates the 200mm stroke directly at the station without running tubes back to a central manifold.
Independent Clamp Station
Perfect for a standalone clamping fixture. The integrated 4M210 valve means the cylinder switches itself, saving manifold space and simplifying machine wiring.
Remote Gating Mechanism
Suited for parts rejection gates on a large machine frame. The self-contained pneumatic action eliminates long tube runs and reduces response delay.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X200-08A the Right Choice?
When sizing, compare both directions: this 50mm bore gives 982 N push and 825 N pull at 0.5 MPa. If you need more force, the 63mm bore offers 1559 N push; if less is required, the 40mm provides 628 N. Confirm your coil is AC220V with terminal entry before ordering. 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 limit, never the 1.0 MPa cylinder body rating. The built-in valve routes air and is not a load lock; for held loads add an external rod lock or pilot-operated check valve. At 200mm stroke, side-load is minimal, but for any stroke over 300mm ensure external guiding.
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 SAUF50X200-08A FAQ
It pushes 982 N and pulls 825 N at 0.5 MPa. The built-in valve is a 4M210-08 (1/4" port, Cv 0.89, 5 cycles/sec max) running on AC220V. You must size the force within the valve's 0.15-0.8 MPa operating window, not the 1.0 MPa cylinder body rating.
Yes. The default factory setting retracts the rod when the coil is energised. You can change it to extend-when-energised simply by repositioning the built-in valve. Because the valve is integrated, no remote valve or extra plumbing is needed to swap the action.
