Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X75-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X75-08B is a genuine double-acting profile-type cylinder with a Ø32mm bore, 75mm 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 SAUF32X75-08B
The AirTAC SAUF32X75-08B is a double-acting profile cylinder with a built-in 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 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 in the 0.15-0.8 MPa valve window, it delivers a 402N push force at 0.5 MPa. The integrated 1/4" valve port provides 16mm2 flow (Cv 0.89) at up to 5 cycles per second. The DC24V terminal coil offers IP65 protection. For sizing, the safe working load is roughly 241N, translating to a 20kg vertical lift with a 2:1 margin.

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 SAUF32X75-08B Is Used
Decentralized Clamping
Ideal for isolated clamping stations where running a dedicated line from a main manifold is impractical, switching directly from a local DC24V signal.
Inline Diverting
Perfect for small package diverters on conveyors, using the integrated 5/2 valve to achieve rapid 5 cycle/sec actuation without extra tubing.
Compact Ejection
Fits into tight machinery footprints for part ejection, saving space and eliminating the need to mount a separate 4M210 valve nearby.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X75-08B the Right Choice?
Size against the 402N push at 0.5 MPa, stepping up to a 40mm bore if more force is needed, or down if less. This 32mm bore uses a 4M210 valve with a 1/4" port. The DC24V terminal entry coil must match your control voltage. Default action retracts the rod when energised, but you can reposition the valve to extend on signal. Always size within the 0.15-0.8 MPa valve range, not the 1.0 MPa cylinder body rating. The valve only routes air, so add an external rod lock or pilot-operated check valve for load holding. Since the 75mm stroke is under 300mm, side-load guides are less critical, but always confirm alignment. This SKU lacks a magnet and cannot take a sensor.
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 SAUF32X75-08B FAQ
It pushes 402N and pulls 345N at 0.5 MPa. The built-in valve is a 4M210-08 (1/4" port, Cv 0.89, 16mm2 flow, 5 cycles/sec max). The coil is DC24V terminal entry. You must size force within the 0.15-0.8 MPa valve operating window, not the 1.0 MPa cylinder body rating.
By default, the rod retracts when the coil is energised. You can reconfigure it to extend on signal by physically repositioning the built-in valve. This self-switching design means you need no remote valve, saving manifold space and tubing.
