About the Airtac B04-SAID ISO Standard Cylinder Dedicated for Construction Machinery B04-SAID100X150S
The AirTAC B04-SAID100X150S is a double-acting, double-rod ISO 15552 profile cylinder. The "B04-" prefix designates this as a construction-machinery dedicated variant of the SAID100X150-S, meaning it is mechanically identical to the base model but tailored for heavy-equipment builders. Because a rod exits both end covers, the annulus area is equal on both sides, yielding a consistent 3681 N of force in both extend and retract directions at 0.5 MPa.
This through-rod design allows you to mount a primary workpiece on the front rod end and a position flag or cam on the rear. The extruded aluminum barrel features sensor grooves on both sides, and the included magnet (-S) supports CMSE reed and DMSE electronic switches for dual-side positioning. It uses a G1/2 port, a 25 mm carbon steel rod, and adjustable air cushions at both ends to decelerate the piston smoothly.

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-SAID ISO Standard Cylinder Dedicated for Construction Machinery B04-SAID100X150S Is Used
Heavy Equipment Actuation
Drives symmetric push-pull mechanisms on construction machinery where equal force is required in both directions to move heavy structural components.
Twin-Station Transfer
Simultaneously operates two separate tooling stations from a single cylinder, using both rod ends to transfer parts in perfect synchronization.
Anti-Rotation Guidance
Keeps heavy loads guided against rotation during vertical or horizontal movement, leveraging the double-rod structure for added stability.
Is the Airtac B04-SAID ISO Standard Cylinder Dedicated for Construction Machinery B04-SAID100X150S the Right Cylinder?
Choose this 100 mm bore when an application requires balanced bidirectional force, as the twin-rod configuration provides 3681 N equally in both directions—unlike a single-rod SAI which has a lower pull force. If your mechanism needs less force, stepping down to the 80 mm bore yields 2268 N both ways. Note that a plain SAID does not hold position when air pressure is lost; for suspended loads requiring a safety lock, consider the BSAID clamp-lock variant or an external pilot check valve.
For this 150 mm stroke, side-load stress on the rod bearing is moderate, but always ensure external guidance for heavy off-center loads. This cylinder is dimensionally interchangeable per ISO 15552 and uses the SAID mounting subset (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting the FB, CA, CB, and CR brackets found on single-rod models.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/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/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac B04-SAID ISO Standard Cylinder Dedicated for Construction Machinery B04-SAID100X150S FAQ
Because it is a double-rod cylinder, the force is identical in both directions. It provides 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and 6626 N at 0.9 MPa for both extend and retract strokes.
The B04- prefix indicates this is a construction-machinery dedicated variant of the SAID100X150-S. It is mechanically identical to the standard AirTAC SAID100X150-S, with the same ISO 15552 dimensions, G1/2 port, and physical specs, simply designated for heavy-equipment applications.
