This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement B06-SAID40X50S, 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-SID40X50S
The AirTAC Airtac B06-SID Battery Dedicated ISO Standard Cylinder B06-SID40X50S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø40mm bore and 50mm stroke, G1/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the B06-SAID40X50S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac B06-SID Battery Dedicated ISO Standard Cylinder B06-SID40X50S
The AirTAC B06-SID40X50S is a double-acting, double-rod ISO 15552 cylinder where a rod exits both ends on one piston, ensuring push and pull force are equal (528 N at 0.5 MPa). The B06- prefix marks this as a battery-manufacturing dedicated variant, mechanically identical to the base SID40X50S with a 40 mm bore, 50 mm stroke, G1/4 port, and M12x1.25 rod thread. As the SID line is discontinued, the direct replacement is the SAID40X50S. The SAI family uses an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life.
Because both faces use the rod-side area, force is identical in both directions. This design prevents rod torsion and allows the back rod to carry a sensor cam. Note that air cushions only decelerate near stroke end; for held loads on battery lines, use an external rod lock or SAIL/BSAI variant.

Where the Airtac B06-SID Battery Dedicated ISO Standard Cylinder B06-SID40X50S Is Used
Battery Cell Stacking
Equal-both-ways force provides stable, anti-rotation pressing during prismatic cell stacking and alignment in module assembly.
Tab Welding Clamp
The rear rod carries a sensor cam to confirm clamp position for battery tab welding while the front rod applies 528 N force.
Pack Handling Transfer
Drives two synchronized tooling arms from one piston for smooth pack handling transfer without torsion, fitting ISO 15552 mounts.
Replacing the Airtac B06-SID Battery Dedicated ISO Standard Cylinder B06-SID40X50S with the B06-SAID40X50S
To replace the discontinued B06-SID40X50S, select the SAID40X50S, which matches the 40 mm bore, 50 mm stroke, G1/4 port, and ISO 15552 mounting interface (Basic, FA, LB, TC). Size both ways by verifying the equal 528 N force at 0.5 MPa meets your requirement, or step to neighbouring bores (32 mm or 50 mm) for different loads. A double rod is right when you need anti-rotation stability or a back rod to drive a second tool. The -S suffix means a piston magnet is present for CS1-B/DS1-B switches. For this 50 mm stroke, side-load is minimal, but for strokes >=300 mm ensure guide alignment to prevent binding.
Replacement checklist
- ✓ Same ISO 15552 interface → B06-SAID40X50S
- ✓ 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-SID40X50S FAQ
Yes, the SID line is discontinued. The direct replacement is the SAID40X50S. The B06- prefix simply marks this as a battery-manufacturing dedicated variant of the base SID40X50S; mechanically, every spec (40 mm bore, 50 mm stroke, G1/4 port, M12x1.25 thread) is identical. The SAID uses an upgraded piston seal and current AirTAC switches.
Because it is a double-rod cylinder, force is equal both ways: 528 N at 0.5 MPa, 739 N at 0.7 MPa, and 950 N at 0.9 MPa. The air port is G1/4. Speed is 30-800 mm/s.
