This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement B04-SAID80X1000S, 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-SID80X1000S
The AirTAC Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID80X1000S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 1000mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the B04-SAID80X1000S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID80X1000S
The AirTAC B04-SID80X1000S is a double-acting, double-rod ISO 15552 cylinder where the B04- prefix marks it as a construction-machinery dedicated variant—mechanically identical to the standard SID80X1000S. A rod exits both ends on one piston, meaning both faces use the rod-side area and push/pull force is equal both ways (2268 N @0.5 MPa). This model is discontinued; the direct replacement is the SAID80X1000S, sharing the same 80mm bore, 1000mm stroke, G3/8 port, and M20x1.5 rod thread. The SAI upgrade uses an upgraded two Y-shaped one-way piston seal for low start-up pressure and long life.
Buyers gain two distinct advantages: the back rod can carry a sensor cam or drive two tools simultaneously while resisting rotation, and existing ISO 15552 mounting hardware (FA, LB, TC) can be reused directly. Note that air cushions only decelerate; for load holding without live air, use an external rod lock or SAIL/BSAI variant.

Where the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID80X1000S Is Used
Excavator Linkage Actuation
Drives synchronized dual-tool mechanisms on heavy equipment, utilizing the equal-both-ways force to push and pull construction machinery linkages without stroke variance.
Crusher Feed Alignment
Uses the dual-rod anti-rotation property to keep rigid alignment when shifting heavy aggregate feed chutes, preventing binding under high side-load conditions.
Drilling Rig Guide Carriage
Employs the rear exiting rod to carry a sensor cam for precise position feedback on drilling rig carriages, matching speeds up to 800 mm/s.
Replacing the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID80X1000S with the B04-SAID80X1000S
To replace the discontinued B04-SID80X1000S, drop in the SAID80X1000S—identical ISO 15552 interface, 80mm bore, 1000mm stroke, and G3/8 port. Size both ways using the equal-both-ways force: 2268 N @0.5, 3175 N @0.7, 4082 N @0.9. If less force is needed, step down to a 63mm bore (1402 N @0.5); if more, step up to 100mm (3681 N @0.5). A double rod is right when you need anti-rotation, a back-rod sensor cam, or dual-tool driving. Reuse FA, LB, or TC mounts. The -S magnet fits legacy CS1-B/DS1-B switches (SAI uses current switches). For this 1000mm stroke, add external guides to prevent rod bending under side loads.
Replacement checklist
- ✓ Same ISO 15552 interface → B04-SAID80X1000S
- ✓ 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-SID80X1000S FAQ
Yes, this construction-machinery dedicated cylinder is discontinued. The direct replacement is the SAID80X1000S. It shares the same ISO 15552 interface, 80mm bore, 1000mm stroke, G3/8 port, and equal-both-ways force. The SAI family also adds SAIL (air-released lock) and BSAI (clamp-lock) variants the SI line lacked.
Force is equal both ways: 2268 N @0.5 MPa, 3175 N @0.7 MPa, and 4082 N @0.9 MPa. The bore is 80mm with a G3/8 air port and M20x1.5 rod thread. Speed is 30-800 mm/s. Air cushions (36mm) only decelerate; use an external rod lock for load holding.
