Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X200-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X200-08B is a genuine double-acting profile-type cylinder with a Ø32mm 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 SAUF32X200-08B
The AirTAC SAUF32X200-08B is a double-acting profile cylinder with a built-in 4M210 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 an ISO 15552 unit of the same bore. It features a 1/8" cylinder port, an M10x1.25 rod thread, and 21mm adjustable cushions.
Operating within the 0.15-0.8 MPa valve window, it delivers 402N push and 345N pull at 0.5 MPa. The integrated valve has a 1/4" port, 16mm2 flow (Cv 0.89), and handles 5 cycles/sec. The DC24V terminal coil offers IP65 protection. For sizing, the safe working load is roughly 241N, and vertical lift capacity is about 20kg with a 2:1 margin. This SKU lacks a 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 (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 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 SAUF32X200-08B Is Used
Decentralized Clamping
Ideal for distributed clamping stations where running individual lines back to a main manifold is impractical, letting each clamp self-switch via its built-in valve.
Compact Part Ejection
Fits into tight machine spaces to eject small parts on a single DC24V signal without requiring a separate remote valve bank nearby.
Inline Diverting
Handles lightweight product diverting tasks along a conveyor, saving installation time by integrating the 4M210 valve directly on the cylinder cap.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X200-08B the Right Choice?
When sizing, compare neighbouring bores: the 32mm bore gives 402N push at 0.5 MPa, while a 40mm bore yields 628N. Confirm the DC24V terminal coil and PT threads suit your setup. The default action retracts the rod when energised, but you can reposition the valve to extend on signal. Always size force within the 0.15-0.8 MPa valve range, not the 1.0 MPa cylinder body rating. Because the valve only routes air, add an external rod lock or pilot-operated check valve to hold loads safely. For this 200mm 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 SAUF32X200-08B FAQ
It generates 402N push and 345N pull at 0.5 MPa. The built-in valve is a 4M210-08 (1/4" port, Cv 0.89, 5 cycles/sec) driven by a DC24V terminal coil. Although the cylinder body rates to 1.0 MPa, the assembled unit must operate within the 0.15-0.8 MPa valve window.
Yes, you can reposition the valve to extend when energised instead of retract. The valve routes air but does not lock the piston; on air loss the rod drifts, so fit an external rod lock or pilot-operated check valve for load holding.
