This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement B06-SAID50X125, 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-SID50X125
The AirTAC Airtac B06-SID Battery Dedicated ISO Standard Cylinder B06-SID50X125 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø50mm bore and 125mm stroke, G1/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the B06-SAID50X125, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac B06-SID Battery Dedicated ISO Standard Cylinder B06-SID50X125
The AirTAC B06-SID50X125 is a double-acting, double-rod ISO 15552 cylinder where the rod exits both ends, making the push and pull force equal at 825 N @0.5 MPa. The B06- prefix marks this as a battery-manufacturing dedicated variant of the base SID50X125, mechanically identical to it for cell and pack assembly tasks. This SID model is discontinued; the direct replacement is the SAID50X125, which reuses the same ISO 15552 mounting interface, G1/4 port, and M16x1.5 rod thread.
Because both faces use the rod-side area, force is equal both ways, providing anti-rotation stability and allowing the back rod to drive a second tool. The SAI replacement upgrades the piston seal with two Y-shaped one-way elements for lower start-up pressure. Note this SKU lacks the -S magnet and cannot take a sensor.

Where the Airtac B06-SID Battery Dedicated ISO Standard Cylinder B06-SID50X125 Is Used
Cell Stacking Alignment
Applies equal both-ways force to align and press battery cells during stacking, using the double-rod design to prevent rotation and maintain precise electrode positioning.
Module Transfer Handling
Drives dual pusher arms on a conveyor line for battery module assembly, leveraging the back rod for synchronized tooling movement without twist.
Tab Welding Clamp
Provides stable clamping for battery tab welding operations, ensuring the workpiece remains secure during the cycle with equal push and pull force.
Replacing the Airtac B06-SID Battery Dedicated ISO Standard Cylinder B06-SID50X125 with the B06-SAID50X125
To replace the discontinued B06-SID50X125, use the SAID50X125 direct: it matches the 50mm bore, 125mm stroke, G1/4 port, and FA/LB/TC mounting. When sizing both ways, verify the equal force of 825 N @0.5 MPa meets your requirement, or step to neighboring bores. A double rod is right when you need anti-rotation resistance or must drive two tools simultaneously. This non-magnetic SKU cannot support sensors. For strokes >=300mm, verify side-load limits. A plain cylinder does not hold loads on air loss; the cushion only decelerates. For held loads use SAIL or an external rod lock.
Replacement checklist
- ✓ Same ISO 15552 interface → B06-SAID50X125
- ✓ 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-SID50X125 FAQ
Yes, the B06-SID50X125 (battery-manufacturing dedicated SID50X125) is discontinued. The direct replacement is the SAID50X125, which shares the same ISO 15552 interface, G1/4 port, and equal force.
Force is equal both ways: 825 N @0.5 MPa, 1154 N @0.7 MPa, and 1484 N @0.9 MPa. The bore is 50mm with a G1/4 air port. It lacks a magnet for sensors.
