Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X350-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X350-08B is a genuine double-acting profile-type cylinder with a Ø32mm bore, 350mm 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 SAUF32X350-08B
The SAUF32X350-08B 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 is 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, this 32mm bore delivers 402N push and 345N pull at 0.5 MPa. The integrated valve provides 16mm2 flow (Cv 0.89) at 1/4" and handles up to 5 cycles per second. The DC24V terminal coil offers IP65 protection with a 0.05s response. For sizing, the safe working load is roughly 241N, and it can vertically lift about 20kg with a 2:1 margin. Note this SKU lacks the S suffix for 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 SAUF32X350-08B Is Used
Decentralized Clamping
Ideal for distributed clamping stations where running a dedicated line from a main manifold is impractical, using the built-in valve to actuate the 350mm stroke directly at the workpiece.
Inline Diverting
Perfect for decentralized conveyor diverters; the one-signal DC24V operation simplifies control wiring while saving manifold space at the main panel.
Compact Ejection
Suits localized ejection gates on modular machinery, providing a 402N push at 0.5 MPa without requiring extra tubing back to a central valve island.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X350-08B the Right Choice?
Size by comparing the 32mm bore to its neighbors: the 40mm bore yields 628N push, while smaller options are unavailable below 32mm. At 0.5 MPa, this model provides 402N push and 345N pull. Always size force within the 0.15-0.8 MPa valve operating range, never the 1.0 MPa cylinder body rating. Confirm the DC24V terminal coil and PT thread meet your electrical specs. The default action retracts the rod when energized, but you can reconfigure it to extend by repositioning the valve. Because the 350mm stroke exceeds 300mm, add external guides to prevent rod bending and side-load damage. This unit has no magnet and cannot take sensors. For load holding, remember the valve only routes air and is not a lock; add an external rod lock or pilot-operated check valve to prevent drift on air loss.
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 SAUF32X350-08B FAQ
It delivers 402N push and 345N pull at 0.5 MPa. The built-in valve is a 4M210-08 (5/2 solenoid) with 1/4" porting, 16mm2 flow (Cv 0.89), and a 5 cycle/sec limit. The DC24V coil runs the assembly within a 0.15-0.8 MPa pressure window; do not size it to the 1.0 MPa cylinder body maximum.
By default, the rod retracts when the coil is energized, but you can reposition the valve to extend on signal. The 5/2 valve only routes air and is not a load lock; the piston will drift on air loss. For held loads, install an external rod lock or pilot-operated check valve.
