TL;DR
MinebeaMitsumi will invest 58 billion yen ($360 million) to expand manufacturing of precision bearings used in AI data centers. The move aims to meet rising demand as AI infrastructure grows globally. The expansion will occur within existing facilities in Southeast Asia, likely Cambodia or Thailand.
Japan’s MinebeaMitsumi has committed to a 58 billion yen ($360 million) investment to expand production of precision bearings used in cooling systems and storage devices for artificial intelligence data centers. The move responds to increasing demand driven by AI infrastructure expansion beyond semiconductor manufacturing, according to the company.
The company plans to build a new manufacturing facility within an existing complex in either Cambodia or Thailand. This facility will focus on increasing bearings output, crucial components for cooling and storage systems in AI data centers. The investment aims to raise production capacity by approximately 30%, addressing the surge in demand for electronic components linked to AI deployment globally.
MinebeaMitsumi stated that the expansion is part of its broader strategy to support the growing AI ecosystem, which requires high-precision components for thermal management and data storage hardware. The company did not specify the exact timeline for the new facility but indicated that construction is underway, with production expected to ramp up in the coming months.
