The world's smallest steel ball bearing
The world's smallest steel ball bearing:
In Tokyo, Japan, on August 28, 2015, Minebea Co., Ltd. announced that its steel ball was awarded the Guinness World Record for the smallest commercial steel ball bearing The title, certified by a representative from Guinness World Records Ltd., has an outer diameter of only 1.4978 mm.
Meyer has been trying to prove its ability to produce the smallest mass-produced bearings. In 2009, it successfully broke the barrier of 2mm steel ball bearing and also paved the way for this ultra-small ball bearing.
The dimensions of this record bearing are 1.5mm outer diameter, 0.5mm inner diameter, and have six steel balls within a length of 0.65mm wide. Its compactness and accuracy conform to JIS code.
Ikuko Koyama said at the Karuizawa factory: 'The 1.5mm outer diameter of the steel ball bearing can break the record thanks to the efforts of our team throughout the production process, I am really happy that the bearings, they are often Neglected. We made a bold attempt to make a bearing size miniaturized and bring it to market. It made me realize that hard work pays off and nothing is impossible.”
