Used as a bearing for micromotors.
From Japan
On 2019-06-14 08:55:34
Although there was no detailed information on bearings in the micromotor manufacturer's catalog, I measured the inner diameter by myself and ordered it against the Monotarou catalog. It matched perfectly and the smooth rotation returned. I am grateful.

I use it as a material for hand spinners.
From Japan
On 2019-05-02 17:09:07
I use it for the material of the hand spinner made as a work kit. We have purchased nearly 500 in total, but are very popular with our customers. Of course, rotation is also good for industrial use, and of course it is also recommended as a hobby.

Create a toy spinner 3d printer and incorporate the rotating part.
From Japan

At that time, spinners were in vogue, and I tried to make my own without being fit for my grandchildren. Even now, it's pleasant, and it's turning around as it was at the time of production.

For home-made balancers of bicycle wheels
From Japan
On 2018-10-01 15:57:19
To adjust the balance of the bicycle wheel, we made jigs with this bearing and a 5 mm aluminum round bar. Because it is an open type, it can degrease grease and drop appropriate rub. The above prescription is because the low load sensitivity increases and the wheel balance becomes easy to check. After the work is finished it is rust protected with suitable all-purpose oil and kept.

For carbon roller roller stand
From Japan
On 2018-07-20 17:17:16
I used it as a roller stand and a holding tool to find a direction in which the carbon pipe easily bends. Although it is a carbon pipe partner of φ 5 ~ 6 mm, it was sealless and resistance was small enough to use it.

Bearing change of hand spinner
From Japan
On 2017-12-12 05:56:25
I degreased and used it, but it was rough and the surrounding was not good. It can not be helped though because it is a method of use outside the assumption of the manufacturer.
