This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement B04-SAID100X200S, with the same bore, stroke, output force, port and mounting, so it fits the same application. The SAI replacement keeps the same ISO 15552 mounting interface, bore, stroke, output force and accessories, so it drops straight into existing fixtures. It is the current-production version of this cylinder with an upgraded piston seal.
Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID100X200S
The AirTAC B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID100X200S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 200mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the B04-SAID100X200S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID100X200S
The AirTAC B04-SID100X200S is a double-acting, double-rod ISO 15552 cylinder where the B04- prefix marks it as the construction-machinery dedicated variant of the base SID100X200S, mechanically identical to it. Because a rod exits both ends on one piston, both faces use the rod-side area, making push and pull force equal at 3681 N @0.5 MPa, 5153 N @0.7 MPa, and 6626 N @0.9 MPa. The bore is 100 mm, the air port is G1/2, the rod-end thread is M20x1.5, and it includes a 36 mm adjustable air cushion at each end. This SID model is discontinued and the direct replacement is the SAID100X200S.
The SAID100X200S retains the same ISO 15552 mounting interface, bore, stroke, and equal-both-ways force, while adding an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life. For this double-rod design, the rear rod can carry a sensor cam to drive two tools simultaneously with anti-rotation stability. The -S suffix indicates a built-in piston magnet for legacy CS1-B/DS1-B switches.

Where the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID100X200S Is Used
Excavator Arm Positioning
Uses the equal both ways force and anti-rotation properties of the double rod to smoothly actuate heavy construction machinery linkage components without twist.
Dual-Tool Drilling Heads
The rear rod exits the back end to carry a sensor cam or drive a secondary tool simultaneously, doubling operational efficiency on heavy-equipment fabrication lines.
Loader Pin Pressing
Applies the 3681 N @0.5 MPa equal force to press and seat pins on machinery assemblies, relying on ISO 15552 mounting for rigid frame attachment.
Replacing the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID100X200S with the B04-SAID100X200S
To replace the discontinued B04-SID100X200S, select the SAID100X200S, which is a direct upgrade keeping the ISO 15552 mounting interface, G1/2 port, M20x1.5 thread, and 200 mm stroke. When sizing both ways, verify the equal push/pull force of 3681 N @0.5 MPa fits your load, or step to neighbouring bores if more force is needed. A double rod is right when you need anti-rotation resistance or synchronized dual-tool driving. Mounting options include Basic, FA, LB, and TC. The -S magnet supports legacy CS1-B/DS1-B sensors. For strokes >=300 mm, confirm the side-load line to prevent rod binding. A plain cylinder does not hold loads on air loss; use an external rod lock or SAIL/BSAI variant for held loads.
Replacement checklist
- ✓ Same ISO 15552 interface → B04-SAID100X200S
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID100X200S FAQ
Yes, the B04-SID100X200S is discontinued. The B04- prefix simply marks it as the construction-machinery dedicated variant of the base SID100X200S. The direct replacement is the SAID100X200S, which shares the same ISO 15552 interface, bore, stroke, G1/2 port, and force, but features an upgraded piston seal.
Because it is a double-rod cylinder, force is equal both ways: 3681 N @0.5 MPa, 5153 N @0.7 MPa, and 6626 N @0.9 MPa. The bore is 100 mm, the air port is G1/2, the rod thread is M20x1.5, and speed is 30-800 mm/s. The air cushion only decelerates near stroke end and does not hold the load on air loss.
