This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement B06-SAID40X250S, 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-SID40X250S
The AirTAC Airtac B06-SID Battery Dedicated ISO Standard Cylinder B06-SID40X250S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø40mm bore and 250mm stroke, G1/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the B06-SAID40X250S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac B06-SID Battery Dedicated ISO Standard Cylinder B06-SID40X250S
The AirTAC B06-SID40X250S is a double-acting, double-rod ISO 15552 cylinder where the B06- prefix designates it as a battery-manufacturing dedicated variant, mechanically identical to the standard SID40X250S. A rod exits both ends of the extruded aluminum barrel on a single piston, meaning both faces use the rod-side area to deliver equal force in both directions (528 N at 0.5 MPa). It features a 16 mm rod, M12x1.25 thread, 27 mm adjustable cushions, and a G1/4 port. This SID model is discontinued and is fully replaced by the direct replacement SAID40X250S.
The SAID40X250S successor shares the exact ISO 15552 interface, bore, stroke, and mounting, but upgrades the piston seal to two Y-shaped one-way elements for lower start-up pressure and longer life. The double-rod design prevents rotation and allows the rear rod to carry a sensor cam, while the -S suffix provides a piston magnet for legacy CS1-B/DS1-B switches.

Where the Airtac B06-SID Battery Dedicated ISO Standard Cylinder B06-SID40X250S Is Used
Battery Cell Stacking
Equal both-ways force drives precise cell stacking and separation in battery module assembly, maintaining alignment without rotational drift.
Tab and Busbar Handling
The double-rod configuration supports synchronized transfer of battery tabs and busbars across conveyor lines, using the rear rod for cam tracking.
Pack Transfer and Sorting
Ideal for battery pack sorting stations where stable push-pull cycles are required to index heavy trays without single-rod force mismatch.
Replacing the Airtac B06-SID Battery Dedicated ISO Standard Cylinder B06-SID40X250S with the B06-SAID40X250S
To replace the discontinued B06-SID40X250S, specify the SAID40X250S, which preserves the 40 mm bore, 250 mm stroke, G1/4 port, and ISO 15552 mounting interface (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because force is equal both ways, verify your push and pull requirements against the 528 N (at 0.5 MPa) rating, stepping up to a 50 mm bore if higher force is needed. A double-rod cylinder is the right choice when you need anti-rotation stability or want to drive two tools simultaneously. Keep the -S option for magnet sensing. For this 250 mm stroke, ensure adequate side-load alignment to prevent rod binding.
Replacement checklist
- ✓ Same ISO 15552 interface → B06-SAID40X250S
- ✓ 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-SID40X250S FAQ
Yes, the B06-SID40X250S is discontinued. The direct replacement is the SAID40X250S. The B06- prefix simply marks it as the battery-manufacturing dedicated variant of the base SID40X250S, so all physical specs remain identical. The SAID successor uses the same ISO 15552 mounting interface, bore, stroke, and G1/4 port, but adds an upgraded piston seal.
As a double-rod cylinder, push and pull forces are equal: 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. Note that a plain cylinder does not hold loads on air loss; the air cushion only decelerates near stroke end. For held loads, use an external rod lock or the SAIL/BSAI lock variant.
