Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X300S-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X300S-08B is a genuine double-acting profile-type cylinder with a Ø32mm bore, 300mm 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 SAUF32X300S-08B
The SAUF32X300S-08B is a double-acting profile cylinder with a built-in AirTAC 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 32mm bore, 1/8" cylinder port, M10x1.25 rod thread, and a 21mm adjustable cushion.
Operating within the 0.15-0.8 MPa valve window, it delivers 402N push and 345N pull at 0.5 MPa. The integrated valve handles 1/4" porting with a 16mm2 flow (Cv 0.89) and 5 cycles/sec. The DC24V terminal coil is IP65 rated. For sizing, the safe working load is roughly 241N (60% of the 0.5MPa push), offering a vertical lift capacity of about 20kg with a 2:1 margin. The -S suffix denotes a piston magnet for CMSG/DMSG/EMSG sensors.

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 SAUF32X300S-08B Is Used
Decentralized Clamping
Ideal for a machining cell where each clamping station uses one coil signal to actuate independently, saving manifold space.
Inline Diverters
Perfect for routing packages on a conveyor line, mounting directly at the divert point without running long tubing to a central bank.
Compact Stops
Serves as a localized pallet stop in a high-density storage system, using the built-in valve to minimize pneumatic plumbing overhead.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X300S-08B the Right Choice?
Size by comparing neighboring bores: the 40mm bore yields 628N push at 0.5MPa versus 402N on this 32mm bore. Confirm the DC24V terminal entry and PT threads suit your controls. The default action retracts the rod when energized, 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. The valve routes air and is not a lock; add an external rod lock or pilot-operated check valve to hold loads. For this 300mm stroke, use external guides to prevent rod bending and side-load wear.
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 SAUF32X300S-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) running on DC24V. You must size the force within the valve's 0.15-0.8 MPa operating window, even though the cylinder body rates to 1.0 MPa.
The default action retracts the rod when the coil receives a signal. You can reconfigure it to extend-when-energised simply by repositioning the valve on the cap. This self-switching design means no remote valve is needed.
