Airtac B04-SAUD Construction Machinery Dedicated Standard Cylinder B04-SAUD50X200
The AirTAC B04-SAUD Construction Machinery Dedicated Standard Cylinder B04-SAUD50X200 is a genuine double-acting profile-type standard air cylinder with a Ø50mm bore and 200mm stroke, 1/4" 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-SAUD50X200
The B04-SAUD50X200 is an AirTAC double-acting, double-rod profile cylinder. The B04- prefix marks it as the construction-machinery dedicated variant of the SAUD50X200, mechanically identical to the base model. A rod exits both ends, meaning both faces use the rod-side area to deliver equal force of 825 N each way at 0.5 MPa. The extruded aluminum profile is shorter than an ISO 15552 cylinder of the same 50mm bore.
This symmetric thrust suits non-rotating and twin-tool duties on heavy equipment. With a 1/4" port and M16x1.5 rod thread, it runs at 30-800 mm/s. This SKU lacks a magnet, so it cannot take a magnetic switch.

Theoretical Output Force (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 825 N | 825 N |
| 0.7 MPa | 1155 N | — |
| Max (@1.0 MPa) | 168 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-SAUD50X200 Is Used
Excavator Linkage
Drives synchronized twin-tool actuation on compact excavator arms, using equal both-ways force to prevent twist during dig cycles.
Crane Outrigger Lock
Provides non-rotating push and pull for heavy-equipment outrigger mechanisms, maintaining precise alignment under varying loads.
Loader Valve Panel
Shifts diverter valves on construction machinery where the shorter profile barrel saves critical envelope space.
Is the Airtac B04-SAUD Construction Machinery Dedicated Standard Cylinder B04-SAUD50X200 the Right Cylinder?
Size both ways against the 825 N equal force at 0.5 MPa: step down to the 40mm bore for 528 N, or up to the 63mm bore for 1402 N. Choose this double-rod build when you need anti-rotation guidance, synchronized twin-tool driving, or a back rod to carry a sensor cam. Mounting is limited to Basic, FA flange, and LB foot styles, matching the AirTAC SC series. At 200mm stroke, external side-load guidance is recommended. Note this SKU has no -S magnet and cannot accept CMSG or DMSG sensors.
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-SAUD50X200 FAQ
The B04- prefix marks this as the construction-machinery dedicated variant of the SAUD50X200, sharing identical specs. Force is equal both ways because rods exit both ends: 825 N at 0.5 MPa, 1154 N at 0.7 MPa, and 1484 N at 0.9 MPa. It uses a 1/4" port.
No to both. A plain cylinder drifts on air loss because the air cushion only decelerates near stroke end; use an external rod lock or pilot-operated check valve to hold a load. Also, this SKU lacks the -S magnet, so it cannot accept CMSG or DMSG switches.
