Motorbike front fork
From Japan

I use it to escape the twist of the front fork spring of the bike. Since the outer diameter of the bearing purchased this time was 24 mm and the outer diameter of the spring was about 22.5 mm Bearings and washers We got 1 mm less outside diameter and put them in the inner pipe. I got better feeling comfortable ride!

The part I used before was ruined and deteriorated, the central part collapsed and the sphere was taken off The one I purchased this time was thought that the sphere was made in a stable form so it was very good. I was able to use the mixer smoothly

Replacement of rotating spindle bearing spindle
From Japan
On 2016-10-03 20:38:13
Since it was abnormal noise when the rotary chair rotated for more than 20 years, it exchanged for this item which is similar in size. The abnormal noise also disappeared and it started to move smoothly. Because it is a Japanese manufacturer's item, I am not worried about durability, but it is a wait-and-see.

Used for drilling machine 45 years ago
From Japan
On 2015-01-30 13:48:01
I used it to replace the bearings used for the spindle of the old drilling machine. Sound also becomes quiet and rotation is smooth. Purchased at this price, the repair cost also increased cheaply.
