This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement B06-SAID40X125S, 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-SID40X125S
The AirTAC Airtac B06-SID Battery Dedicated ISO Standard Cylinder B06-SID40X125S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø40mm bore and 125mm stroke, G1/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the B06-SAID40X125S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac B06-SID Battery Dedicated ISO Standard Cylinder B06-SID40X125S
The AirTAC B06-SID40X125S 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 SID40X125S. Because a rod exits both ends on one piston, both faces use the rod-side area, making push and pull force equal at 528 N @0.5 MPa. This model is discontinued; its direct replacement is the SAID40X125S, which retains the G1/4 port, M12x1.25 thread, and 27mm adjustable cushions.
The SAI replacement introduces an upgraded piston seal using two Y-shaped one-way elements for low start-up pressure and long life. A plain cylinder does not hold loads on air loss; cushions only decelerate near stroke end, so use an external rod lock or SAIL/BSAI variant for held loads.

Where the Airtac B06-SID Battery Dedicated ISO Standard Cylinder B06-SID40X125S Is Used
Cell Stacking Press
Applies equal both-ways force for prismatic cell stacking and alignment, using the double-rod anti-rotation property to maintain parallel electrode contact without deflection.
Module Transfer
Drives dual pushers on a battery module assembly line simultaneously from one center-mounted cylinder, ensuring synchronous movement of cell arrays.
Tab Welding Clamp
Holds battery tabs flat for laser welding; the rear rod carries a sensor cam for precise position feedback while the front rod applies 528 N clamping force.
Replacing the Airtac B06-SID Battery Dedicated ISO Standard Cylinder B06-SID40X125S with the B06-SAID40X125S
To replace the discontinued B06-SID40X125S, specify the direct replacement SAID40X125S, which reuses the exact ISO 15552 mounting interface (Basic, FA, LB, TC) and -S magnet for CS1-B/DS1-B switches. Size both directions by the equal force: 528 N @0.5 MPa. If more force is needed, step up to the 50mm bore (825 N); if less is required, drop to the 32mm bore (345 N). A double rod is right when you need anti-rotation stability or must drive two tools simultaneously. For this 125mm stroke, side-load is minimal, but for strokes >=300mm ensure guide alignment to prevent rod binding.
Replacement checklist
- ✓ Same ISO 15552 interface → B06-SAID40X125S
- ✓ 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-SID40X125S FAQ
Yes, the B06-SID40X125S (battery-manufacturing dedicated variant of SID40X125S) is discontinued. The direct replacement is the SAID40X125S. It shares the same ISO 15552 interface, 40mm bore, 125mm stroke, G1/4 port, and mounting, but adds an upgraded piston seal.
Force is equal both ways (push and pull) because it is a double-rod cylinder: 528 N @0.5 MPa, 739 N @0.7 MPa, and 950 N @0.9 MPa. Operating speed is 30-800 mm/s. The cylinder uses a G1/4 air port and M12x1.25 rod thread.
