This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement B06-SAID50X350S, 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-SID50X350S
The AirTAC Airtac B06-SID Battery Dedicated ISO Standard Cylinder B06-SID50X350S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø50mm bore and 350mm stroke, G1/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the B06-SAID50X350S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac B06-SID Battery Dedicated ISO Standard Cylinder B06-SID50X350S
The AirTAC B06-SID50X350S is a double-acting, double-rod ISO 15552 cylinder where the battery-manufacturing dedicated B06- prefix denotes a variant mechanically identical to the base SID50X350S, built for cell and pack assembly lines. A rod exits both ends on one piston, meaning both faces use the rod-side area and push/pull force is equal both ways (825 N @0.5 MPa). This model is discontinued; the direct replacement is the SAID50X350S, sharing the same 50mm bore, 350mm stroke, G1/4 port, and M16x1.5 rod thread.
The SAI family upgrades the piston seal with two Y-shaped one-way elements for low start-up pressure and long life. The -S suffix indicates a built-in piston magnet for legacy CS1-B/DS1-B switches. Note that air cushions only decelerate near stroke end; an external rod lock or pilot-operated check valve is required to hold loads on air loss.

Where the Airtac B06-SID Battery Dedicated ISO Standard Cylinder B06-SID50X350S Is Used
Battery Cell Stacking
Equal both-ways force drives precise electrode stacking and separation in cell assembly, ensuring consistent pressure on both advance and retract strokes.
Dual-Tool Tab Welding
The rear rod extension simultaneously carries a sensor cam or secondary actuator, synchronizing tab welding and handling without extra manifolds.
Module Pack Transfer
Anti-rotation stability from the double-rod design securely indexes battery modules along conveyor lines during pack assembly, preventing load twist.
Replacing the Airtac B06-SID Battery Dedicated ISO Standard Cylinder B06-SID50X350S with the B06-SAID50X350S
To replace the discontinued B06-SID50X350S, specify the SAID50X350S, which reuses the exact ISO 15552 mounting interface (Basic, FA, LB, TC) and physical dimensions. Because it is a double-rod design, force is equal both ways at 825 N @0.5 MPa, 1154 N @0.7 MPa, and 1484 N @0.9 MPa; if more force is needed, step up to the 63mm bore, or drop to the 40mm bore for lighter duties. A double rod is the right choice when you need anti-rotation stability, dual tool driving, or a back rod to carry a sensor cam. The -S magnet supports legacy CS1-B/DS1-B switches. At 350mm stroke, external guides are recommended to prevent rod bending under side loads.
Replacement checklist
- ✓ Same ISO 15552 interface → B06-SAID50X350S
- ✓ 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-SID50X350S FAQ
Yes, the B06-SID50X350S is discontinued. The direct replacement is the SAID50X350S. The B06- prefix simply marks it as a battery-manufacturing dedicated variant; mechanically it is identical to the SID50X350S. The SAID replacement shares the same 50mm bore, 350mm stroke, G1/4 port, and ISO 15552 mounting.
Because it is a double-rod cylinder, force is equal both ways: 825 N @0.5 MPa, 1154 N @0.7 MPa, and 1484 N @0.9 MPa. The air port is G1/4.
