This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement B06-SAID40X400, 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 B06-SID Battery Dedicated ISO Standard Cylinder B06-SID40X400
The AirTAC Airtac B06-SID Battery Dedicated ISO Standard Cylinder B06-SID40X400 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø40mm bore and 400mm stroke, G1/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the B06-SAID40X400, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac B06-SID Battery Dedicated ISO Standard Cylinder B06-SID40X400
The AirTAC B06-SID40X400 is a double-acting, double-rod ISO 15552 cylinder where the 'B06-' prefix marks it as a battery-manufacturing dedicated variant, mechanically identical to the standard SID40X400. A rod exits both ends on one piston, meaning both faces use the rod-side area and push/pull force is equal both ways (528 N @0.5 MPa). This model is discontinued; the direct replacement is the SAID40X400, which reuses the same ISO 15552 mounting interface, 40mm bore, 400mm stroke, G1/4 port, and M12x1.25 rod thread. The SAI replacement also uses an upgraded piston seal (two Y-shaped one-way elements for long life and low start-up pressure).
Because the second rod can drive two tools simultaneously or carry a sensor cam, it provides excellent anti-rotation stability. Note this SKU lacks the -S magnet and cannot take a magnetic switch. A plain cylinder does not hold its load on air loss; the 27 mm adjustable air cushion only decelerates near stroke end, so use an external rod lock for held loads.

Where the Airtac B06-SID Battery Dedicated ISO Standard Cylinder B06-SID40X400 Is Used
Battery Cell Stacking
Equal both-ways force drives precision stacking mechanisms in prismatic cell assembly, ensuring consistent pressure on both extend and retract strokes.
Dual-Side Tab Welding
The twin rods drive opposing welding electrodes simultaneously, maintaining perfect parallelism during battery tab welding operations.
Module Transfer Handling
Anti-rotation stability allows accurate pick-and-place of battery modules across conveyor lines without torsional deflection during transit.
Replacing the Airtac B06-SID Battery Dedicated ISO Standard Cylinder B06-SID40X400 with the B06-SAID40X400
To replace the discontinued B06-SID40X400, drop in the SAID40X400 directly—it matches the ISO 15552 interface, bore, stroke, and G1/4 port without mechanical changes. Size both ways by checking neighboring bores (32mm or 50mm) against your equal-both-ways force requirements. A double-rod design is right when you need anti-rotation stability, dual-tool driving, or a back rod to carry a sensor cam. Reuse FA, LB, or TC mounts. As this unit lacks the -S magnet, it cannot support sensing; if needed, upgrade to a -S SAID model (legacy CS1-B/DS1-B sensor accuracy). At 400mm stroke, use external guides to prevent rod bending and side-load damage. For load holding on air loss, use an external rod lock or pilot-operated check valve.
Replacement checklist
- ✓ Same ISO 15552 interface → B06-SAID40X400
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac B06-SID Battery Dedicated ISO Standard Cylinder B06-SID40X400 FAQ
Yes, the B06-SID40X400 (battery-manufacturing dedicated variant of SID40X400) is discontinued. The direct replacement is the SAID40X400, which shares the same ISO 15552 interface, 40mm bore, 400mm stroke, G1/4 port, and mounting. The SAI family also adds SAIL (air-released lock) and BSAI (clamp-lock) variants.
Force is equal both ways: 528 N @0.5 MPa, 739 N @0.7 MPa, and 950 N @0.9 MPa. The air port is G1/4. Speed is 30-800 mm/s.
