Mitsubishi Precision Co Ltd. designed and built a fidget spinner based on MinebeaMitsumi Inc.'s ball bearings to break the Guinness world record for "Longest duration spinning a fidget spinner on one finger." The team of 50 people spent 6 months creating and perfecting the design, with a heavy brass outer ring, and a lightweight aluminum center section, which spun for 24 min 46.34 sec.
"By incorporating technologies used for space satellites, we were able to realise smoothness and overwhelming rotation time that we’ve never seen before. We also applied bearing manufacturing technologies used for aircraft as well as wheels and rings. We use materials with the highest strength among aluminum alloys and highest quallity brass so that wheels and rings are thoroughly thinner and lighter than conventional ones," - Shigeru None.
