This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement B06-SAID40X25, 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-SID40X25
The AirTAC Airtac B06-SID Battery Dedicated ISO Standard Cylinder B06-SID40X25 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø40mm bore and 25mm stroke, G1/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the B06-SAID40X25, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac B06-SID Battery Dedicated ISO Standard Cylinder B06-SID40X25
The AirTAC B06-SID40X25 is a double-acting, double-rod ISO 15552 cylinder where a rod exits both ends on one piston, making push and pull force equal at 528 N @0.5 MPa. The B06- prefix marks this as a battery-manufacturing dedicated variant of the base SID40X25, mechanically identical to it for cell and pack assembly lines. This 40 mm bore model features a 16 mm rod, G1/4 port, M12x1.25 thread, and 27 mm adjustable cushions. As the SID line is discontinued, the direct replacement is the SAID40X25, which reuses the same ISO 15552 interface, bore, stroke, and mounting.
The SAI replacement upgrades the piston seal with two Y-shaped one-way elements for lower start-up pressure and longer life. Because the second rod occupies the rear cap, force is equal both ways and the back rod can drive a second tool or sensor cam. This non-magnetic SKU cannot take a switch, and the air cushion only decelerates near stroke end—it does not hold loads on air loss.

Where the Airtac B06-SID Battery Dedicated ISO Standard Cylinder B06-SID40X25 Is Used
Battery Cell Stacking
Applies equal both-ways force for pressing and separating battery cell layers in automated stacking modules.
Tab Welding Transfer
Uses the double-rod anti-rotation property to move battery tabs precisely into welding position without drift.
Module Pack Handling
Drives dual pickers from both rod ends to load and unload battery modules symmetrically on the line.
Replacing the Airtac B06-SID Battery Dedicated ISO Standard Cylinder B06-SID40X25 with the B06-SAID40X25
To replace the discontinued B06-SID40X25, specify the SAID40X25, which is a direct match for the ISO 15552 mounting interface, G1/4 port, and 25 mm stroke. Size both ways by confirming the 528 N @0.5 MPa equal force is sufficient, or step up to a 50 mm bore if more thrust is needed. A double rod is right when you need equal push/pull force, anti-rotation stability, or a back rod to carry a sensor cam. Reuse FA, LB, or TC mounts. Because this SKU lacks the -S magnet, it cannot take a sensor. For any stroke over 300 mm, verify side-load limits to prevent guide wear.
Replacement checklist
- ✓ Same ISO 15552 interface → B06-SAID40X25
- ✓ 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-SID40X25 FAQ
Yes, the B06-SID40X25 is discontinued. The direct replacement is the SAID40X25. The B06- prefix simply marks it as the battery-manufacturing dedicated variant of the base SID40X25, so the SAID40X25 matches its ISO 15552 interface, 40 mm bore, 25 mm stroke, and G1/4 port exactly.
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 bore is 40 mm with a G1/4 air port, a 16 mm rod, M12x1.25 thread, and 27 mm adjustable cushions.
