Airtac B04-SAUD Construction Machinery Dedicated Standard Cylinder B04-SAUD32X300
The AirTAC B04-SAUD Construction Machinery Dedicated Standard Cylinder B04-SAUD32X300 is a genuine double-acting profile-type standard air cylinder with a Ø32mm bore and 300mm 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-SAUD32X300
The B04-SAUD32X300 is an AirTAC construction-machinery dedicated double-rod profile cylinder. The B04- prefix marks it as a heavy-equipment variant of the SAUD32X300, mechanically identical to the base model. It features a 32mm bore, 300mm stroke, 1/8" port, and an extruded aluminum barrel that is shorter than an ISO 15552 cylinder of the same bore.
Because a rod exits both ends, output force is equal in both directions at 345 N each way at 0.5 MPa. The twin-rod design provides anti-rotation guidance, and a Viton H seal option extends operating temperature to 0-150 C.

Specifications follow the official AirTAC SAU series datasheet. Confirm against the product label before installation. Thread options: PT (blank) / G (BSPP). A high-temperature seal (0-150 °C) is available.
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-SAUD32X300 Is Used
Excavator Panel Pusher
Drives cabin panels on heavy equipment using equal push and pull force, preventing twist during synchronized actuation.
Crane Load Aligner
Uses twin rods to keep lifting forks aligned on construction sites, ensuring stable vertical movement without rotation.
Heavy Equipment Brake Lever
Shifts twin brake linkages simultaneously in machinery cabs, relying on the compact profile to fit tight chassis spaces.
Is the Airtac B04-SAUD Construction Machinery Dedicated Standard Cylinder B04-SAUD32X300 the Right Cylinder?
When sizing this double-acting unit, compare both ways: stepping down is not an option below 32mm, but stepping up to the 40mm bore provides 528 N at 0.5 MPa if your load requires more force. Choose this 32mm bore when you need synchronized motion, twin-tool driving, or non-rotating anti-twist guidance. Mounting is limited to Basic, FA flange, and LB foot styles compatible with the AirTAC SC series. Because this SKU lacks the -S magnet, it cannot accept CMSG or DMSG sensors. For the 300mm stroke, always use external guides to prevent rod bending under side loads.
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-SAUD32X300 FAQ
The B04- prefix marks this as the construction-machinery dedicated variant of the SAUD32X300, sharing identical specifications. Force is equal both ways: 345 N at 0.5 MPa, 483 N at 0.7 MPa, and 621 N at 0.9 MPa. The 1/8" port and 12mm rod ensure balanced operation.
No. This SKU lacks the -S magnet, so it cannot accept magnetic sensors. Additionally, the air cushion only decelerates near stroke end; it does not lock. For vertical load holding on air loss, you must use an external rod lock or pilot-operated check valve.
