悠九特製不鏽鋼軸承 Special Stainless Steel Ball Bearing by Yonity

這是悠九推出的不鏽鋼弧形軸承，它用手去撥動就可以持續轉三十秒以上。他內、外圈是不鏽鋼的，可以預防生鏽的問題，保持器也是不鏽鋼的，滾珠一樣採用最高等級的十顆小滾珠，而目前滾珠的材料暫時列為機密，跟一般市面上的材料不一樣，也不是陶瓷滾珠。外圈也進行鏡面拋光處理，可以讓你在做花式的時候更加滑順。

    This is the special stainless steel bearing by Yonity. It can keep spinning over 30 second by hand. The materiel of retainer, outer race and inner race are stainless steel. So, there are no rusty problem. The roller is the high-class 10 balls set. But we can not tell the materiel of roller. It is the secret why it can spin so long. The outer race has been polished. The polishing finish makes it smoother when you doing tricks.

我們做的就是不一樣 We made the different.

塑膠球軸心
The axle of plastic yo-yo.

我們悠九做得就是不一樣，即便是塑膠溜溜球我們一樣可以使用獨家的軸心系統，不像市面上的廠商他們的塑膠球設計幾乎都一樣。這再次證明了我們是真的有在用心設計的。

    We always make the different. We use the Exclusive Axle System even design the plastic yo-yo. Other plastic yo-yos in market almost are the same design of bearing and axle. This improves that we are surely DESIGN a yo-yo again.

溜溜球是怎麼設計的? How did the yo-yo designed?

圖一　溜溜球的素描草圖
Figure 1. The sketch of yo-yo.

或許有很多玩家會很好奇我們溜溜球到底是怎麼設計出來的？這是一個非常好的問題。大部分的玩家都認為，設計溜溜球就像室內設計一樣，畫個漂亮的素描草圖（圖一），再把草圖實踐做出實體就好。實際上設計溜溜球完全不是這麼簡單的一回事，一般的溜溜球廠商都是採用一次做出多個樣本，再一一交給專業玩家測試，最後選出最好的樣本來量產。但這個方法是二十幾年前工程業界上所採用的方法，且非常的不科學。

How did the yo-yo designed? Most players thought that just like interior design. To draw a sketch (Fig 1.), and make it real. However, it is not so simple. Generally, most factories would make many yo-yos which are similar. And give those to the expert player to test. Finally, they would manufacture the yo-yo which the expert thought that was best of those. Even so, this procedure is not so scientific. This is the way of development about 20 several years ago.
