Bearing change of hand spinner

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

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.

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".

Use degreased. Originally it was around 3 minutes, but in a few days it got strange sounds and strange sounds came around for only about one minute. However, it is good quality as it goes without being damaged.

Purchase because of reel overhaul Because it is an old model, it is convenient to be prepared separately from the manufacturer as there is no even drawing

Of two purchases, one is perfect, the other has some play (there is no problem if used under normal load)
