This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement B06-SAID40X150S, 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.

The AirTAC Airtac B06-SID Battery Dedicated ISO Standard Cylinder B06-SID40X150S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø40mm bore and 150mm stroke, G1/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the B06-SAID40X150S, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC B06-SID40X150S 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 SID40X150S. Because a rod exits both ends, the push and pull forces are equal at 528 N (@0.5 MPa). This model is discontinued; the direct replacement is the SAID40X150S, which reuses the exact ISO 15552 mounting interface and G1/4 port.
The SAI upgrade features an improved two-piece Y-shaped piston seal for low start-up pressure and long life. Note that a plain cylinder drifts on air loss; the 27 mm adjustable cushions only decelerate near stroke end, so use an external rod lock for held loads.

The B06-SAID40X150S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Legacy SI-family variants: SID (double rod), SIJ (adjustable stroke) — each maps to its SAI equivalent (SID→SAID, SIJ→SAIJ). Rod material: carbon steel (blank) / SUS420J2 (A) / SUS304 (B).
Uses the equal both-ways force and inherent anti-rotation properties to precisely press and align prismatic battery cells during module stacking without deflection.
Drives two welding heads simultaneously from opposite ends of the piston, maintaining perfectly synchronized pressure on battery cell tabs.
Mounts a sensor cam on the rear rod to confirm stroke position while the front rod pushes battery packs between conveyor stations.
To replace the discontinued B06-SID40X150S, specify the SAID40X150S. It matches the 40 mm bore, 150 mm stroke, 16 mm rod, M12x1.25 thread, G1/4 port, and ISO 15552 mounting (Basic, FA, LB, TC). Force is equal both ways (528 N @0.5 MPa); if you need more lift, step up to the 50 mm bore (825 N @0.5 MPa), or drop to the 32 mm bore (345 N @0.5 MPa) if lower. A double rod is ideal when you need anti-rotation stability or want to drive two tools from one piston. The -S suffix means a magnet is present for legacy CS1-B/DS1-B sensors. For this 150 mm stroke, side-load is minimal, but for strokes >=300 mm, ensure guide alignment to prevent rod binding.
Replacement checklist
Yes, the B06-SID40X150S (battery-manufacturing dedicated SID40X150S) is discontinued. The direct replacement is the SAID40X150S. It shares the same ISO 15552 interface, 40 mm bore, 150 mm stroke, G1/4 port, and mounting, but adds an upgraded piston seal.
Because it is a double-rod cylinder, 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. It operates at 0.15-1.0 MPa with a speed range of 30-800 mm/s.
