My yoyo is almost as good as if it wasn t washed after the shaft, why?

I also have sunshine, but I also mentioned a little bit after washing and idling, and it took more than 8 minutes. So I guess your approach is wrong. Let's talk about how I did it!

1.Start by putting your bearings in a small airtight container, preferably the one from Po Chai Pills, which is just the right size, and of course, you can also use "belly packing". Put the bearing in, pour in zippo oil (soaked in the bearing 5mm), and shake it for 2 3 minutes (depending on the degree of dirtiness of the bearing).

2.Take out the bearings and let them dry, about 30 minutes to 1 hour. Then rinse the container you just used to wash the bearings and dry it (be sure to remember, this is important).

Then put the bearing into the container, pour in the zippo oil, soak it overnight, take it out the next day, clamp the bearing out with tweezers (remember to use pliers and other tools to break the two contact heads when it is used to clamp things, it helps to jam things), and then use the two contact heads to jam the inner ring (note: the inner ring is the innermost hole in the bearing), wave the outer ring by hand, and then quickly put it back into the container, and let the bearing idle in the zippo oil (repeat n times). Finally, take the bearing out, put it in a ventilated place to cool and dry, and it's done.

Remember: the time used to cool and dry the bearing cannot be saved. Otherwise, the effect is not so good.

Agree with l What ball is yours? The bad ball washed even worse.

Soak in fire engine oil for 10 minutes and lubricate it.

Some of them can't be washed, and they get worse when washed.

The inner wall of the bearing bead bearing due to the friction at high speed when the yoyo is idling, so there is generally no rust, the outer wall of the bearing (the part that can be seen in the bearing) is not a big problem, if the ball is idling there is a big noise, indicating that there are impurities, just clean it, and the bearing is only necessary to replace the cage damage or the bearing has reached the end of life.

Bearing is an important component in contemporary machinery and equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy.

According to the different friction properties of moving elements, bearings can be divided into two categories: rolling bearings and sliding bearings. Among them, rolling bearings have been standardized and serialized, but compared with sliding bearings, its radial size, vibration and noise are larger, and the highest is also higher.

Rolling bearings are generally composed of four parts: outer ring, inner ring, rolling element and cage, strictly speaking, it is composed of six parts: outer ring, inner ring, rolling element, cage, seal and lubricating oil. It mainly has an outer ring, an inner ring, and a rolling element, which can be defined as a rolling bearing. According to the shape of the rolling elements, rolling bearings are divided into two categories: ball bearings and roller bearings.

1. The external rust can be gently wiped with fine sandpaper, provided that the size cannot be affected, and then the anti-rust oil can be added;

2. If it is a non-separable bearing raceway that rusts, it will be scrapped, and if it is a separate type and the size is large, the rust can also be wiped a little to prevent rust, and it can be cleaned and continued to be used;

3. Clean kerosene for cleaning. However, the anti-rust effect of kerosene is relatively poor, so you should buy professional anti-rust oil.

In fact, you can only use or throw away this bearing.

Because after rusting.

The structure inside was destroyed.

Some people say it's okay to get it off with sandpaper.

But it can greatly affect the performance of the yoyo.

I suggest you change it.

Rusty? The first is that the event you use is too long, and the second is that the bearings are of inferior quality. It is recommended that you quickly throw away the rusty bearings and go to some yo-yo stores to buy some like what Audi high-precision kk, American YYF brand kk bearings, etc., Audi high-precision kk is 35 yuan, I am like this here, there may be deviations.

First of all, if you use alcohol, you must use 100%, otherwise it will increase the chance of rust, it is recommended to use zippo fire engine oil (master washing shafts are used for this) There are many specific operations on the Internet, I will not explain here.

It doesn't matter how long the bearing is soaked in oil, as long as the dust is washed off, it is okay to install a dust cap to prevent dust from entering the bearing (otherwise, it will have to be washed all the time).
