Do you have any requirements for bearings in Yoyo 2A?

2A does not have much requirement for the idling time of the ball, as long as the speed of the tyrant is **sensitive, 2A will generally not have a problem, if it is not sensitive enough, you can stick a layer of double-sided tape on the star stripe (this will shorten the idling time, but the fast play feels very good!) If the rope is practiced often, it will be changed every four days, but the rope used for the two hands can be often swapped, which can improve the life of the rope.

Yoyo ball bearings are generally divided into three types: ordinary type, special type and special reinforced version, and choose the right bearing according to your needs.

1.Most of the ordinary yo-yo ball bearings are deep groove ball bearings made of bearing steel, which belong to the miniature bearing class and the inner diameter size ranges from 3mm-6mm. This type of bearing has a high rotation speed, and most of them are open, but there are also sealed types.

2.The best advantage of this bearing is that the U-shaped groove design conforms to the use characteristics of the yo-yo, so that the speed of the yo-yo is smooth.

3.Special strengthened yoyo bearing, also known as high-precision KK bearing, as the name suggests, is a KK bearing with relatively high accuracy, accuracy and material are the main factors affecting the performance of the bearing, directly determine the quality of the bearing, and the idle time is naturally longer than other bearings. The biggest advantage of this special bearing is that the rope will be in the bearing as much as possible when playing with the ball, reducing the friction between the rope and the ball wall

Buy the superlative: high-precision KK. Buy it back and don't wash the shaft. Because the manufacturer has already washed it once!

Buy a high-precision KK, wash it once with the best oil, and change it when it rusts. It's a bit extravagant, but it's good.

**Bearings are best not to buy, just foreign, easy to wear out, recommended you to buy ten beads!

Buy a stainless steel KK bearing with the same specifications as your ball.

How to install side bearings on yoyos:

Method 1: First of all, align the side shaft with the small hole on the side, and then use a special screwdriver for four-wheel drive vehicles to suck up the screws in the package, align the small holes, and then screw it on, and then it can be successfully installed.

Method 2: Tighten with screws, a similar 888 L3. First place the bearing, fix it into the clamping position with a rubber ring, and then place the white cap on the side shaft to install it successfully.

Method 3: Let the buyer install it at the place where you bought the yo-yo, free of charge.

The bearing of the yo-yo is an important part that makes him rotate smoothly and lastingly, the side bearing sold is a spiral hole on the side of the fire silver electric s, the hole can be installed with the side bearing, after installing it, you can grab the side bearing with your hand and pull the yo-yo away, but he will keep idling;

Basically, the side bearing is a plastic or any material that wraps a bearing, because it depends on the bearing to make him have a way to rotate, so it is similar to the bearing;

It is recommended that if you don't play with side bearings, you can go to the firepower silver electric S-size bearings and buy them, otherwise it is basically useless to buy side bearings.

I want to go to the Audi store and ask the technician to open it, but the cost is 20 yuan!

But I've found a way you might as well give it a try: first find something sharp (like scissors, screwdrivers...) Pierce the lid on the side and poke a hole, then pry the screwdriver to the side and open it immediately.

PS: You don't have to worry about damaging the yoyo, the material of the Thunder S is solid plastic and very hard.

I also use Thunder S, because he himself is not suitable for installing side axles, and if he is installed, it will cause the weight of the ball to be uneven and easy to skew, and I have changed the rainbow now, and it has its own side axles, so that will not happen.

Personally, I think it's better not to install it will make the ball unbalanced... Affect the feel... I usually even have a side shaft, I dismantle it...

It is recommended that you do not play with the side bearings you can go to the fire silver electric S size bearing and then buy it, otherwise it is basically useless to buy the side bearing, in addition, the fire silver electric s play side bearing will basically get tired quickly, so it is recommended that you find the bearing, do not buy the side bearing.

Hehe, hello. The principle of side bearing and bearing is a concept, but the side bearing will rotate much slower than the bearing because it has to be pulled by the user to achieve the effect of rotation. I suggest that your firepower silver electric s better buy a kk bearing, too high-grade s can't bear it, if you like to play, I recommend you buy a good ball. Thank you.

1) Low power motor, 2) Self-maintaining concentricity.

It is called "KK bearing", and the difference between it and ordinary deep groove ball bearing is that the outer ring is curved, that is, with a groove. See Fig

It is the thing that makes a yo-yo man turn.

It is the core part of the yo-yo, and it allows it to idle for a long time.

There are many of them: large ball bearings, grooveless bearings, KK bearings, bearings fixed with rubber plates, high-precision KK bearings.
