Type E Bearing (Body Stainless Steel: Ceramic Sphere)
It is a bearing of Type E which is said to be the so-called yomega size.
Bearings using ceramic balls that are much harder and lighter than steel balls.
Especially at high speed rotation, deformation is reduced due to the hardness of the ball, and the centrilycing force is also reduced because it is light.
The staying force of rotation is improved.
In 2019JN, it is a bearing that Takuma Yamamoto also used.
Because it is made of stainless steel except for the ball, it is resistant to rust and the new state lasts for a long time.
