About the Airtac B04-SAID ISO Standard Cylinder Dedicated for Construction Machinery B04-SAID100X100
The AirTAC B04-SAID100X100 is a double-acting, double-rod ISO 15552 profile cylinder engineered for construction machinery. The B04- prefix designates it as the construction-machinery dedicated variant of the standard SAID100X100, meaning it is mechanically identical to the base model. Because a rod exits both ends, the annulus area is symmetrical, yielding equal push and pull forces of 3681 N at 0.5 MPa in either direction.
This through-rod design allows you to mount the primary workpiece on one end and a position flag or cam on the rear rod end. The extruded aluminum barrel features sensor grooves on both sides for flexible CMSE or DMSE switch mounting, while the carbon steel rod and M20x1.5 thread provide robust side-load resistance for heavy-equipment cycles.

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-SAID100X100 Is Used
Heavy Equipment Actuation
Drives symmetric-force push and pull mechanisms on construction machinery where equal thrust both ways is required for balanced lifting or pressing.
Twin-Station Transfer
Simultaneously moves two synchronized loads from a single piston, using both rod ends to actuate parallel stations on a heavy-duty assembly jig.
Anti-Rotation Slides
Keeps heavy structural components guided and prevented from twisting during extension, leveraging the double-rod geometry for superior rotational stability.
Is the Airtac B04-SAID ISO Standard Cylinder Dedicated for Construction Machinery B04-SAID100X100 the Right Cylinder?
Choose this 100 mm bore when a 63 mm bore (1402 N both ways at 0.5 MPa) is insufficient for heavy-duty construction actuation, but you want to avoid the larger 125 mm class. A twin-rod cylinder is selected over a single-rod SAI when the mechanism requires dual-side guidance to prevent rotation, or when a rear rod is needed to drive a secondary mechanism. The B04-SAID100X100 uses a PT G1/2 port and accepts Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts (omitting FB, CA, CB, CR).
As a standard double-acting cylinder, it does not hold its position if air pressure is lost; the adjustable air cushions only decelerate the piston near stroke ends. For dead-load holding on a construction rig, supplement this with an external rod lock or a pilot-operated check valve. At a 100 mm stroke, side-load stress on the rod bearing is minimal, but always ensure the load is guided externally for optimal bearing life.
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-SAID100X100 FAQ
Because it is a double-rod cylinder, the effective area is identical on both sides. It provides an equal force of 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and 6626 N at 0.9 MPa for both extension and retraction.
The B04- prefix indicates this is AirTAC's construction-machinery dedicated variant of the SAID100X100. It is mechanically identical to the standard SAID100X100, maintaining the exact same ISO 15552 dimensions, 100 mm bore, and G1/2 port, but is designated for heavy-equipment builders.
