Airtac B04-SAUD Construction Machinery Dedicated Standard Cylinder B04-SAUD32X125
The AirTAC B04-SAUD Construction Machinery Dedicated Standard Cylinder B04-SAUD32X125 is a genuine double-acting profile-type standard air cylinder with a Ø32mm bore and 125mm stroke, 1/8" air ports and adjustable end cushioning. Its hard-anodized aluminum-profile barrel is shorter than an ISO 15552 cylinder of the same bore, and it shares SC-series mounting accessories.

About the Airtac B04-SAUD Construction Machinery Dedicated Standard Cylinder B04-SAUD32X125
The B04-SAUD32X125 is an AirTAC double-acting, double-rod profile cylinder. The B04- prefix marks this as the construction-machinery dedicated variant of the SAUD32X125, sharing identical mechanics. Because a rod exits both ends, the push and pull force is equal, delivering 345 N each way at 0.5 MPa. It uses a 1/8 inch port and an extruded aluminum barrel that is shorter than a standard ISO 15552 unit of the same bore.
This compact design prevents piston twist during operation and allows driving twin tooling simultaneously. Without the -S suffix, this SKU cannot accept magnetic sensors. Note that the end cushions only decelerate; an external rod lock is needed to hold loads securely.

Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 346 N | 346 N |
| 0.7 MPa | 484 N | — |
| Max (@1.0 MPa) | 70 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac B04-SAUD Construction Machinery Dedicated Standard Cylinder B04-SAUD32X125 Is Used
Excavator Door Latch
Synchronizes double tooling to lock and unlock heavy cab doors on earthmoving equipment with equal push and pull force.
Crusher Feed Gate
Provides non-rotating anti-twist guidance for opening and closing aggregate hopper gates on mobile crushing machinery.
Loader Spool Valve
Shifts twin pilot valves simultaneously on wheel loaders, using the compact profile to fit tight chassis spaces.
Is the Airtac B04-SAUD Construction Machinery Dedicated Standard Cylinder B04-SAUD32X125 the Right Cylinder?
Select this 32 mm bore when you need 345 N of equal bidirectional force at 0.5 MPa. If your construction equipment requires less push, step down is not an option as 32 mm is the smallest, but if you need more power, step up to the 40 mm bore which provides 528 N both ways. The double-rod architecture is ideal for anti-rotation guidance or carrying a secondary tool. Mounting is limited to Basic, FA flange, and LB foot, matching the AirTAC SC series. At 125 mm stroke, side loads are minimal, but always guide the load externally. Since this SKU lacks the -S magnet, it cannot use CMSG or DMSG switches.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB — same as SC).
- check Installation by qualified personnel per AirTAC docs.
Airtac B04-SAUD Construction Machinery Dedicated Standard Cylinder B04-SAUD32X125 FAQ
The force is equal in both directions due to the double-rod design. It generates 345 N at 0.5 MPa, 483 N at 0.7 MPa, and 621 N at 0.9 MPa. The operating pressure range is 0.15-1.0 MPa, and it uses a 1/8 inch port.
The B04- prefix indicates this is the construction-machinery dedicated variant of the SAUD32X125, with no mechanical changes. A plain cylinder drifts on air loss; the adjustable cushions only decelerate. Use an external rod lock for load holding.
