The AirTAC Airtac B06-MI Battery Dedicated Cylinder B06-MI32X300SU is a genuine double acting round-body mini air cylinder with a Ø32mm bore and 300mm stroke, 1/8" air ports and a stainless-steel barrel and rod for mildly corrosive environments.
The B06-MI32X300SU is AirTAC’s battery-manufacturing dedicated variant of the MI32X300SU, meaning the B06- prefix simply designates its industry application without altering the physical specs. As a double-acting round-body mini cylinder, it features a stainless-steel barrel and piston rod that resist mild corrosion and washdowns better than painted alternatives. It delivers a push force of 402.2 N and a pull force of 345.6 N at 0.5 MPa, utilizing a 1/8" air port and an M10x1.25 male rod thread.
The riveted construction remains compact, while fixed TPU bumper pads decelerate the stroke end to absorb impact. Because this SKU includes the -S magnet, it supports CMSG, DMSG, and EMSG position switches for precise tracking on automated lines.

| 0.7 MPa | 563 N | 484 N |
| Max (@1.0 MPa) | 82 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

MI-family variants: MI / MIC (double acting ±cushion), MSI / MTI (single acting push / pull), MID / MICD (double rod ±cushion), MIJ / MICJ (double rod, adjustable stroke ±cushion). Back covers CA / U / R / CM. Mounting LB / FA / SDB / TC.
Drives the precise vertical stacking of lithium battery cells during module assembly, utilizing the 20.5 kg safe vertical lift capacity to handle layered cell groups securely.
Indexes battery tabs under welding heads with 402.2 N of push force at 0.5 MPa, ensuring stable metal contact during the high-speed ultrasonic welding process.
Actuates diverting gates on conveyor lines to route finished battery packs, relying on the stainless steel construction to withstand occasional coolant mist exposure.
When sizing this 32 mm bore, stepping down to a 25 mm bore drops the push force to 245.3 N at 0.5 MPa, while stepping up to a 40 mm bore increases it to 628.3 N. The U 90-degree back cover on this unit provides specific rear mounting and port orientation flexibility for tight battery assembly cells. If your battery stacking process loses air or the valve centers, the piston will drift and cannot maintain a held load; the TPU bumpers only soften the end of stroke rather than acting as a brake. For suspended loads, integrate an external rod lock or a pilot-operated check valve. The 300 mm stroke is well within the 500 mm maximum standard stroke for this bore, though maintaining precise alignment is critical to prevent rod bending over longer side-load distances.
Quick checklist
This 32 mm bore cylinder has a 1/8" air port and an M10x1.25 male rod thread. The thrust is 402.2 N push and 345.6 N pull at 0.5 MPa, 563 N push and 483.8 N pull at 0.7 MPa, with a theoretical maximum force of 82 kgf at 1.0 MPa.
The B06- prefix indicates this is a battery-manufacturing dedicated variant of the MI32X300SU, mechanically identical to the base model. It uses fixed TPU bumper pads to decelerate at the stroke end rather than an adjustable air cushion, and the -S suffix means it contains a magnet for CMSG, DMSG, or EMSG sensors.
