3x10x5 bearing

This bearing requires the use of 2.4mm diameter steel balls, which are also used for linear guide rails. I bought a guide rail slider and the merchant included a package of 2.4mm steel balls! So we designed this bearing to utilize the unused steel balls.
这个轴承需要使用2.4mm直径的钢珠，也是直线导轨所用的钢珠，我买了一个导轨滑块，商家附赠了一包2.4mm的钢珠！所以就设计了这个轴承来利用没用完的钢珠。
