About the Airtac B06-MI Battery Dedicated Cylinder B06-MI40X25SU
Delivering 628.3 N of push force at 0.5 MPa, the AirTAC B06-MI40X25SU is a robust 40 mm bore, double-acting round-body mini cylinder built for battery manufacturing lines. The B06- prefix designates this as a battery-manufacturing dedicated variant of the MI40X25SU, meaning it is mechanically identical to the base model but earmarked for cell, module and pack assembly tasks. Its stainless-steel barrel and piston rod provide a real edge over painted alternatives, resisting mild corrosion and washdown in damp production environments. A 1/4" port feeds the 16 mm rod, and the U back cover provides a 90-degree port and mounting orientation for tight machine layouts.
Fixed TPU bumper pads absorb the impact at stroke extremes, decelerating the motion without offering adjustable cushioning. Because it carries the -S suffix, this unit includes a piston magnet for direct switching via CMSG, DMSG or EMSG sensors. For practical sizing, plan for roughly 377 N of actual work at 0.5 MPa, which translates to lifting about 32 kg vertically with a 2:1 safety margin.

Where the Airtac B06-MI Battery Dedicated Cylinder B06-MI40X25SU Is Used
Battery Cell Stacking
Provides the 628.3 N push force needed to press and align lithium-ion prismatic cells tightly during module stacking operations.
Tab Welding Clamp
Holds battery tabs firmly in place under 0.5 MPa pressure for automated laser welding, utilizing the 90-degree U cover for compact robotic cell integration.
Pack Diverting
Actuates heavy pack-routing gates on conveyor lines, where the stainless-steel construction withstands occasional coolant and washdown spray.
Is the Airtac B06-MI Battery Dedicated Cylinder B06-MI40X25SU the Right Cylinder?
When sizing this 40 mm bore unit, note that stepping down to a 32 mm cylinder drops the 0.5 MPa push force to 402.2 N, while this 40 mm bore provides 628.3 N. As the largest standard round-body mini cylinder size, there is no larger MI bore available. The 25 mm stroke keeps the rod compact and minimizes side-load bending moments, but always ensure the load is axially aligned to prevent guide wear. The U back cover suits 90-degree mounting arrangements.
Remember that a plain double-acting cylinder drifts when air is removed or the valve is centered, as the fixed TPU pads only soften the end of stroke and act as neither a lock nor a brake. If your battery-handling fixture must hold a vertical load during an air loss event, integrate an external rod lock or a pilot-operated check valve. Position detection is fully supported via CMSG, DMSG or EMSG switches thanks to the integrated -S magnet.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G)
- ✓ Magnet (-S) for sensors?
- ✓ Back cover (CA/U/R/CM) & mount (LB/FA/SDB/TC)
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Do not dismantle the riveted front/back covers.
- check Use correct back cover (CA/U/R/CM) & mount (LB/FA/SDB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac B06-MI Battery Dedicated Cylinder B06-MI40X25SU FAQ
This 40 mm bore double-acting cylinder uses a 1/4" port. It generates 628.3 N push and 527.8 N pull at 0.5 MPa, increasing to 879.6 N push and 738.9 N pull at 0.7 MPa. The theoretical maximum force is 128.1 kgf at 1.0 MPa.
The B06- prefix simply marks this as AirTAC's battery-manufacturing dedicated variant of the MI40X25SU, with no mechanical changes to the stainless-steel riveted construction or fixed TPU bumpers. It does not feature a load lock; the piston will drift if air is lost, so an external rod lock or pilot check valve is required for vertical holding.
