I was searching for years. 34 years I was tolerating the rack I was using because it was difficult to move, but I finally found it. Thank you for the amateur's easy-to-understand illustration. But the amount was large to search and it was a little hard.
It is used as a caster for the stand of the welding machine in the factory.

Previously, we used other companies' products, but the performance is equivalent, the price is inexpensive compared to the previous one, and I am glad that you can receive it as soon as you ask. We are pleased that our work can be improved as the factory side can improve immediately.
