The smallest steel ball bearing in the world
In Tokyo, Japan, Meibeia Limited announced that its steel balls were awarded the Guinness World Records title of the smallest commercial ball bearing, and the outer diameter of its steel balls was only 1.4978 mm certified by a representative from Guinness World Records Limited.
Melbourne has been trying to prove that it has the ability to produce the smallest mass bearing. In 2009, it successfully broke the barrier of the 2mm steel ball bearing and paved the way for the ultra-small ball bearing.
The record size of the bearing is 1.5 mm in outer diameter and 0.5 mm in Inner diameter, with six steel balls in the length of 0.65 mm in width. Its compactness and accuracy accord with JIS code.
Yuko Koyama said in the light well plant: "The 1.5 mm diameter of steel ball bearings can break the record thanks to our team's efforts in the whole production process, I am really happy, bearings, they are often overlooked. We are bold to try to manufacture miniaturized bearing size, and can be marketed. It made me realize that there is nothing that can't be achieved without effort. "
