This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement B04-SAID80X200, 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-SID80X200
The AirTAC Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID80X200 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 200mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the B04-SAID80X200, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID80X200
The AirTAC B04-SID80X200 is an ISO 15552 double-acting double-rod cylinder where the B04- prefix designates it as the construction-machinery dedicated variant of the base SID80X200, mechanically identical to it. A rod exits both ends on one piston, meaning both faces use the rod-side area and push/pull force is equal at 2268 N @0.5 MPa, 3175 N @0.7 MPa, and 4082 N @0.9 MPa. This model is discontinued and superseded by the direct replacement SAID80X200, which shares the exact 80mm bore, 200mm stroke, G3/8 port, and M20x1.5 rod thread.
The double-rod architecture provides anti-rotation stability and allows the back rod to carry a sensor cam or drive two tools simultaneously, while the ISO 15552 mounting interface lets you reuse existing FA, LB, or TC brackets. The SAI replacement upgrades the piston seal to two Y-shaped one-way elements for lower start-up pressure and longer life. Note this non-magnetic SKU cannot take a switch, and air cushions only decelerate; use an external rod lock or SAIL/BSAI variant for held loads.

Where the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID80X200 Is Used
Excavator Linkage
Equal both-ways force drives dual-tool actuation on heavy-equipment linkages where the B04- prefix indicates construction-machinery dedication.
Anti-Rotation Clamp
The twin-rod design prevents rotation during high-force clamping of structural steel, maintaining precise alignment under 3175 N @0.7 MPa.
Synchronized Gate
Drives opposing gates simultaneously from one piston, using the back rod for balanced motion in dusty construction-machinery environments.
Replacing the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID80X200 with the B04-SAID80X200
To replace the discontinued B04-SID80X200, install the direct replacement SAID80X200, matching the 80mm bore, 200mm stroke, G3/8 port, and 1500mm max standard stroke. Size both ways by checking equal force: this bore outputs 2268 N @0.5 MPa, so if you need less force step down to the 63mm bore (1402 N), or step up to 100mm (3681 N) for more. A double rod is right when you need anti-rotation resistance or want to drive two tools from one piston. Mounting uses ISO 15552 Basic, FA, LB, or TC styles. Because this SKU lacks the -S magnet, it cannot accept sensors. For strokes >=300mm, verify side-load limits to prevent guide wear. Speed is 30-800 mm/s.
Replacement checklist
- ✓ Same ISO 15552 interface → B04-SAID80X200
- ✓ 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-SID80X200 FAQ
Yes, the B04-SID80X200 is discontinued. The direct replacement is the SAID80X200. The B04- prefix simply marks it as the construction-machinery dedicated variant of the base SID80X200, so the SAID replacement shares the exact 80mm bore, 200mm stroke, G3/8 port, and ISO 15552 mounting interface.
Because it is a double-rod cylinder, force is equal in both directions: 2268 N @0.5 MPa, 3175 N @0.7 MPa, and 4082 N @0.9 MPa. The air port is G3/8.
