Airtac B04-SAUD Construction Machinery Dedicated Standard Cylinder B04-SAUD100X200S
The AirTAC B04-SAUD Construction Machinery Dedicated Standard Cylinder B04-SAUD100X200S is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 200mm stroke, 1/2" 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-SAUD100X200S
The B04-SAUD100X200S is an AirTAC construction-machinery dedicated double-rod cylinder. The B04- prefix marks it as a heavy-equipment variant, mechanically identical to the base SAUD100X200S. It uses a hard-anodized extruded aluminum profile barrel, making it shorter than an ISO 15552 cylinder of the same bore. A rod exits both ends, meaning push and pull forces are equal at 3681 N each way at 0.5 MPa. The 1/2" port and M20x1.5 rod thread handle high flow.
With the -S option, a built-in magnet allows CMSG, DMSG or EMSG switches to track position. For high-temperature environments, Viton H seals extend operation to 150 C.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3682 N | 3682 N |
| 0.7 MPa | 5154 N | — |
| Max (@1.0 MPa) | 751 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-SAUD100X200S Is Used
Excavator Valve Actuation
Synchronizes dual pilot valves on heavy equipment with equal push and pull thrust, preventing rotational twist during harsh hydraulic cabinet cycles.
Crusher Feed Diversion
Drives two opposing guide gates simultaneously from one piston, ensuring balanced material routing on construction aggregate lines.
Track Alignment Pusher
Uses the protruding back rod as a mechanical cam to confirm stroke completion via a proximity switch on tracked machinery.
Is the Airtac B04-SAUD Construction Machinery Dedicated Standard Cylinder B04-SAUD100X200S the Right Cylinder?
When sizing this 100 mm bore, moving down to the 80 mm bore drops the equal force to 2268 N at 0.5 MPa, while no larger standard bore exists. Choose this double-rod configuration when your mechanism requires strict anti-rotation guidance, needs to drive two tools at once, or uses the back rod to trip a switch. Mounting is limited to Basic, FA flange, and LB foot styles, matching the AirTAC SC series. The -S magnet enables electronic or reed sensing. For this 200 mm stroke, ensure external load guides are used to prevent side-loading damage.
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-SAUD100X200S FAQ
The B04- prefix denotes the construction-machinery dedicated variant of the SAUD100X200S, sharing identical specs. Force is equal both ways: 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and 6626 N at 0.9 MPa. The 1/2" port supplies the required volume.
No, a plain double-rod cylinder drifts without live air; the adjustable 29 mm cushions only decelerate near stroke end. For secure load holding on construction equipment, install an external rod lock or pilot-operated check valve.
