I am using it for the wheel part of the cart for the amusement park. Although it is a frequently used fixture, there is no problem that a problem will occur in the bearing. Because the amount of usage is small, purchasing with MonotaRO is very helpful.
I got something of hope with abundant size and variety. When the number of orders is small, please use free shipping bearing tallow in case of large number of orders because this site is cheap. Either way we are very sorry.
