Airtac B04-SAUD Construction Machinery Dedicated Standard Cylinder B04-SAUD63X150S
The AirTAC B04-SAUD Construction Machinery Dedicated Standard Cylinder B04-SAUD63X150S is a genuine double-acting profile-type standard air cylinder with a Ø63mm bore and 150mm stroke, 3/8" 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-SAUD63X150S
The B04-SAUD63X150S is an AirTAC double-acting, double-rod profile cylinder. The B04- prefix marks this as the construction-machinery dedicated variant of the SAUD63X150S, sharing the exact same physical specs. A rod exits both ends on one piston, meaning both faces use the rod-side area. Output force is equal in both directions, delivering 1402 N each way at 0.5 MPa. The 3/8 inch port and M16x1.5 rod thread are fixed by the 63 mm bore.
This extruded aluminum profile barrel is shorter than an ISO 15552 cylinder of the same bore. The dual rods provide anti-rotation guidance and can drive twin tooling or carry a switch cam on the back end. The -S suffix adds a piston magnet for CMSG, DMSG, or EMSG sensors.

Theoretical Output Force (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1402 N | 1402 N |
| 0.7 MPa | 1962 N | — |
| Max (@1.0 MPa) | 286 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-SAUD63X150S Is Used
Excavator Valve Actuation
Drives twin valve stems on heavy equipment with equal push and pull force, preventing rotational twist during hydraulic cycling.
Crusher Tool Sync
Synchronizes dual jaw tooling on construction demolition attachments, ensuring both sides move together without binding.
Back-End Switch Cam
Uses the protruding back rod to trip a CMSG sensor, confirming full retraction in tight heavy-machinery enclosures.
Is the Airtac B04-SAUD Construction Machinery Dedicated Standard Cylinder B04-SAUD63X150S the Right Cylinder?
Size this 63 mm bore against its neighbors: the 50 mm yields 825 N both ways, while the 80 mm provides 2268 N. Choose this double-rod model when your application needs anti-rotation stability, synchronized twin-tool driving, or back-end sensing. Mounting is limited to Basic, FA flange, and LB foot styles, matching the AirTAC SC series. The -S magnet enables position sensing. For any stroke at or over 300 mm, use an external guide to prevent side-load binding.
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-SAUD63X150S FAQ
The B04- prefix denotes the construction-machinery dedicated variant of the SAUD63X150S, mechanically identical to the base model. Force is equal both ways because both chambers carry a rod: 1402 N at 0.5 MPa, 1962 N at 0.7 MPa, and 2523 N at 0.9 MPa.
No, a plain cylinder drifts without live air. The adjustable 21 mm cushions only decelerate near stroke ends. For load holding on construction equipment, install an external rod lock or pilot-operated check valve.
