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.

Bearing change of hand spinner
From Japan
On 2017-10-30 08:28:04
The hand spinner that the customer's child (+ Child) had had used bearings that were so severe so I exchanged it for service. It is completely out of work, but I was very pleased, and I got a job of maintenance so let's do so (laugh) Quality is no problem, and above all else, delivery is earlier than squeezing parts supplier (out of stock) and I am saved.

For teaching materials of junior high school social studies etc
From Japan

Exchange one of the same two hand spinners for this NTN bearing. I compared the students with the original (perhaps the product of China etc). Compared to the original product which has a rough sense of rotation, it is manufactured by NTN which rotates more smoothly than "it does not become comparable". I was able to realize the difference in technology between Japan and other countries. However, as for the hand spinner, which one is the right answer, there are many students that "I do not feel like turning" to be very smooth, and one student raised a voice like "Prius".
