What You Want to Know Most about Yo-Yo Ball bearing

Yo-Yo ball bearings are an indispensable component of  Yo-Yo ball. Many people wonder that how big is the difference between Yo-Yo ball bearing at different prices.

The difference of general 1A ball bearings is nothing more than material (stainless steel, all-ceramic, ceramic ball plus stainless steel mixed type...), cut surface shape (flat shaft, U, V, T, VI, yyr four cut surface, topyo five cut surface...), ball Number (8, 10, double row 16...), ball fixing method (single card, double card), with or without dust cover, weight, shaft thickness...

When the above factors are the same, the manufacturing process and accuracy determine the performance of the bearing (A good bearing runs very smoothly and stably without noise. Different types of bearings have subtle differences in performance, such as 8 beads to 10 The bead's shaft speed is fast, but the stability is a little bit inferior...)

As for the shafts used by balls of different prices, most of them are not much different when the prices are not very different. Mainly depends on the brand and the factory.

Which axis to use for a ball should be mainly determined by the selection of the relevant brand personnel, and then go to the factory to make or purchase. For example, many high-end products of c3 will use the U-axis of American dife-yo, yyr's balls seem to be equipped with dsb (four-section) or NSK, and most of yyf's balls are his own patented T-axis, and the magic has its own bearings printed with the words "Supernatural Skill"...

Among them, NSK and dif are high-end bearings, and the price is relatively higher.

Most of the original bearings on the market are ordinary 10-ball u-shafts, and some have dust caps. The performance of these bearings is uneven, and these bearings don't have names. Sudden bursting of the shaft or instability leads to noise and big ball chattering. It's not surprising either. Sometimes sellers will say that they use selected bearings when they advertise, and these shafts may be relatively better.

Generally speaking, the performance of well-known word-of-mouth bearings will indeed be outstanding. NSK, dif, etc. feel different when used, and they have improved the performance of the ball. But it won't make the ball change too much, the general bearing is enough.

Relatively speaking, I think the maintenance of bearings is more important!

If the noise becomes louder or the shaft bursts, wash the shaft quickly and rescue it. Appropriately adding a little 1A oil (dip a toothpick on the balls) can greatly reduce the risk of shaft burst (adding too much will weaken idling or even sleep alive). The shaft is silent, don’t unscrew the ball often to expose the bearing (without dust cover) to the air to avoid dust, etc., do not serve too hard (many times people are too excited to serve the ball and use the shaft too hard. of).

The above is my personal experience of playing ball. If you have any mistakes or omissions, please correct me and add them.
