This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement B04-SAID80X200S, 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-SID80X200S
The AirTAC Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID80X200S 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-SAID80X200S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID80X200S
The B04-SID80X200S is an AirTAC double-rod ISO 15552 cylinder where the B04- prefix designates the construction-machinery dedicated variant of the base SID80X200S, mechanically identical with a 80mm bore, 200mm stroke, and G3/8 port. A rod exits both ends on one piston, meaning both faces use the rod-side area and push/pull force is equal both ways (3175 N @0.7 MPa). This model is discontinued; the direct replacement is the SAID80X200S, which adds an upgraded two-piece Y-shaped piston seal for lower start-up pressure and longer life.
Because the twin rods share the same effective area, the cylinder provides inherent anti-rotation properties and the back rod can carry a sensor cam to drive two tools simultaneously without requiring extra space. The -S suffix denotes a built-in piston magnet for legacy CS1-B/DS1-B switches. Note that a plain cylinder does not hold loads on air loss; the adjustable 36mm cushions only decelerate near stroke end, so use an external rod lock for held loads.

Where the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID80X200S Is Used
Excavator Linkage Actuation
Drives synchronized heavy-equipment covers or linkage arms on construction machinery where equal push/pull force and anti-rotation stability are critical for safe operation.
Dual-Tool Material Handling
Powers two opposing grippers or clamps via both rod ends simultaneously on a construction-machinery assembly line, maintaining symmetrical force without requiring a secondary cylinder.
Heavy-Equipment Guide Alignment
Positions and straightens structural components using the back rod to carry a sensor cam, ensuring precise feedback in harsh construction-machinery fabrication environments.
Replacing the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID80X200S with the B04-SAID80X200S
To replace the discontinued B04-SID80X200S, specify the SAID80X200S directly—it preserves the ISO 15552 mounting interface, 80mm bore, 200mm stroke, G3/8 port, and M20x1.5 rod thread. Because force is equal both ways (2268 N @0.5 MPa, 4082 N @0.9 MPa), size both directions identically; if downsizing, the 63mm bore yields 1402 N @0.5 MPa, while the 100mm bore yields 3681 N. Choose a double-rod configuration when anti-rotation stability or symmetrical dual-tool driving is required. Reuse existing FA, LB, or TC mounts without modification. The -S magnet supports legacy CS1-B/DS1-B sensors. For strokes of 300mm or longer, verify side-load bearing limits to prevent guide bushing wear.
Replacement checklist
- ✓ Same ISO 15552 interface → B04-SAID80X200S
- ✓ 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-SID80X200S FAQ
Yes, the B04-SID80X200S is discontinued. The direct replacement is the SAID80X200S. The B04- prefix simply marks it as the construction-machinery dedicated variant of the base SID80X200S. The SAID replacement shares the identical ISO 15552 mounting interface, 80mm bore, 200mm stroke, G3/8 port, and force ratings, but features an upgraded piston seal for longer life.
As a double-acting double-rod cylinder, force is equal both ways: 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and 4082 N at 0.9 MPa. It operates at 0.15-1.0 MPa (proof 1.5 MPa), speeds of 30-800 mm/s, and uses a G3/8 port with M20x1.5 rod threads. It does not hold loads without live air.
