About the Airtac B04-SAID ISO Standard Cylinder Dedicated for Construction Machinery B04-SAID100X100S
The AirTAC B04-SAID100X100S is a double-acting, double-rod ISO 15552 profile cylinder. The B04- prefix designates it as the construction-machinery dedicated variant of the SAID100X100-S, built with mechanically identical specs including a 100mm bore, 100mm stroke, and an integrated magnet for CMSE / DMSE sensors. 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 twin-rod architecture provides superior anti-rotation stability and allows you to mount a primary workpiece on the front rod while using the rear rod end to drive a secondary mechanism or trigger a limit flag. It features a robust 25mm carbon steel rod, adjustable air cushions at both ends, and a PT G1/2 port. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting.

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-SAID100X100S Is Used
Heavy Equipment Actuation
Drives robust 3681 N bidirectional mechanisms on construction machinery where the B04- prefix indicates dedicated heavy-equipment deployment.
Twin-Station Synchronization
Uses the through-rod design to move two opposing assemblies at the exact same speed and force, keeping multi-tool processes perfectly aligned.
Anti-Rotation Guiding
Prevents load twisting on heavy slides by utilizing the dual-ended rod for structural stability without needing external guide rails.
Is the Airtac B04-SAID ISO Standard Cylinder Dedicated for Construction Machinery B04-SAID100X100S the Right Cylinder?
Select this 100mm bore cylinder when an application demands high bidirectional force (3681 N at 0.5 MPa) and strict load guidance. If you need less force, stepping down to the 80mm bore yields 2268 N each way. Choose the double-rod SAID over a single-rod SAI when you need to synchronize two stations, prevent rotation, or utilize the rear rod for cam actuation. For heavy equipment, note that a plain SAID does not hold its position if air pressure drops; if your circuit requires load holding without live pressure, consider an external rod lock or the BSAID clamp-lock variant.
As a dimensionally interchangeable ISO 15552 cylinder, it drops in seamlessly for other standard profile cylinders. It uses the reduced SAID mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR brackets. Because the stroke is 100mm, side-load stress on the rod bearing is moderate, but always verify alignment in high-vibration machinery.
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-SAID100X100S FAQ
Because it is a double-rod cylinder, the effective piston area is identical on both sides. It provides an equal extend and retract force of 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and 6626 N at 0.9 MPa.
The B04- prefix marks this as AirTAC's construction-machinery dedicated variant of the SAID100X100-S. It is mechanically identical to the standard SAID100X100-S, maintaining the same ISO 15552 dimensions, G1/2 port, and 25mm rod, simply designated for heavy-equipment builders.
