Airtac B04-SAUD Construction Machinery Dedicated Standard Cylinder B04-SAUD32X250S
The AirTAC B04-SAUD Construction Machinery Dedicated Standard Cylinder B04-SAUD32X250S is a genuine double-acting profile-type standard air cylinder with a Ø32mm bore and 250mm 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-SAUD32X250S
The B04-SAUD32X250S is an AirTAC double-acting double-rod profile cylinder. The B04- prefix marks this as the construction-machinery dedicated variant of the SAUD32X250S, mechanically identical to the base model. Because a rod exits both ends, the push and pull forces are equal at 345 N each way at 0.5 MPa. The extruded aluminum profile barrel makes it shorter than an ISO 15552 cylinder of the same bore.
This 32 mm bore unit features a 1/8" port and a built-in piston magnet (-S) for CMSG, DMSG or EMSG switches. With a 250 mm stroke, keep external side-load guides aligned to prevent binding.

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-SAUD32X250S Is Used
Excavator Panel Pusher
Drives cabin interior panels on heavy equipment using equal push and pull force, preventing twist during alignment.
Loader Linkage Stop
Acts as a synchronized end-stop for dual-tooling arms on construction loaders, using the back rod to trip a limit switch.
Crane Boom Guide
Provides non-rotating lateral guidance for telescopic boom extensions, fitting into tight machinery envelopes.
Is the Airtac B04-SAUD Construction Machinery Dedicated Standard Cylinder B04-SAUD32X250S the Right Cylinder?
When sizing this double-rod unit, the equal force both ways is 345 N at 0.5 MPa. If you need less force, there is no smaller standard SAUD bore. If you need more force, step up to the 40 mm bore which provides 528 N each way at 0.5 MPa. Choose this twin-rod design when your construction equipment needs anti-rotation guidance, synchronized twin-tool driving, or back-end switch cam actuation. Mounting is limited to Basic, FA flange, and LB foot styles, matching the AirTAC SC series. The -S magnet allows solid-state or reed sensors. For this 250 mm stroke, always use external load guides to absorb lateral stress.
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-SAUD32X250S FAQ
The 32 mm bore has a 1/8" port and generates equal force both ways: 345 N at 0.5 MPa, 483 N at 0.7 MPa, and 621 N at 0.9 MPa. The B04- prefix simply denotes the construction-machinery dedicated variant, sharing the exact same physical specs as the SAUD32X250S.
No. A plain double-rod cylinder drifts without live air; the adjustable 21 mm cushions only decelerate near stroke end. For locked load holding on construction machinery, install an external rod lock or pilot-operated check valve.
