A ball bearing with a 1.5mm outer diameter manufactured by MinebeaMitsumi Inc. was recognized by GUINNESS WORLD RECORDS as the Smallest commercially available steel ball bearing on 28 August, 2015. This marks the second accreditation by GUINNESS WORLD RECORDS for MinebeaMitsumi.
Mr. None, Director and Managing Executive Officer of MinebeaMitsumi Inc., who received the certificate, commented as follows:
"Due to the recent popularity of a fidget spinner, ball bearings which are usually not around people's sight have received attention. There are so many kinds of fidget spinners and we decided to challenge the record thinking that if we could do something interesting by using our ball bearings.
I am very happy to be able to prove our ultra-precision machining technology again after 2015 by receiving this accreditation of the world’s Smallest fidget spinner."
