This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement B04-SAID100X175, 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-SID100X175
The AirTAC Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID100X175 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 175mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the B04-SAID100X175, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID100X175
The AirTAC B04-SID100X175 is a double-acting, double-rod ISO 15552 cylinder where a rod exits both ends on one piston, making push and pull force equal at 3681 N @0.5 MPa, 5153 N @0.7 MPa, and 6626 N @0.9 MPa. The B04- prefix marks this as a construction-machinery dedicated variant, mechanically identical to the base SID100X175 with a 100mm bore, 175mm stroke, G1/2 port, and M20x1.5 rod thread. This SKU has no -S magnet and cannot take a sensor.
This SID model is discontinued and the direct replacement is the SAID100X175, retaining the same ISO 15552 interface, bore, stroke, and adjustable 36mm cushions. The SAI upgrade uses a two Y-shaped one-way piston seal for low start-up pressure and long life. Double-rod benefits include anti-rotation and driving two tools from one piston.

Where the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID100X175 Is Used
Excavator Linkage Actuation
Equal both-ways force drives dual opposing wear plates on heavy-equipment pivots, maintaining balanced tension without rod-side force drop.
Crane Counterweight Shift
The rear rod acts as a mechanical stop cam while the front rod shifts the mass, preventing rotation during dynamic loading on site.
Paver Screed Adjustment
Dual external rods simultaneously position left and right screed extensions, ensuring parallel alignment without needing a second cylinder.
Replacing the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID100X175 with the B04-SAID100X175
To replace the discontinued B04-SID100X175, use the SAID100X175 direct, which matches the ISO 15552 mounting interface, G1/2 port, and 175mm stroke. Size both ways by checking neighbouring bores: the 80mm bore yields 2268 N @0.5 MPa, and the 125mm bore yields 5734 N @0.5 MPa, both equal in push and pull. Choose a double-rod cylinder when you need anti-rotation resistance or must drive two tools simultaneously. Reuse FA, LB, or TC mounts directly. For strokes >=300mm, verify side-load limits to prevent guide wear. Note this non-magnetic SKU cannot accept switches; for load holding without live air, use an external rod lock or the SAIL/BSAI lock variant, as cushions only decelerate.
Replacement checklist
- ✓ Same ISO 15552 interface → B04-SAID100X175
- ✓ 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-SID100X175 FAQ
Yes, this construction-machinery dedicated SID100X175 variant is discontinued. The direct replacement is the SAID100X175, which shares the identical ISO 15552 interface, 100mm bore, 175mm stroke, G1/2 port, and equal both-ways force. The B04- prefix only denotes the construction-machinery application and changes no physical specs.
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 air port is G1/2, the rod thread is M20x1.5, and it has adjustable 36mm cushions.
