There is only one bearing, how can a yo yo without a shaft guard sleep.

You can wash the shaft first, adding plenty of lube! As long as it is not a monolithic yo-yo, it can "sleep", and the key is to throw it vertically.

Yoyos can be divided into five types according to their shape: standard, drum, butterfly, weighted butterfly, and ultra-wide weighted butterfly.

Standard type: suitable for kombat and simple tie-up movements, suitable for beginners.

Drum type: suitable for kombat, but it is not easy to tie the string.

Butterfly: Suitable for more complex tie movements, it is the best choice for beginners to advance to intermediate. However, it is not very suitable for Kombat.

Weighted butterfly: This type of ball is heavier and not easy to do, but it has a long idling time and is suitable for complex wire ties. It is a more professional spherical shape.

Ultra-wide weighted butterfly: special for masters, belonging to the ball for the competition, the structure is mostly ball bearing, the longest idle time, easy to tie the line.

There are also points that can be divided according to the structure of the ball

Yoyo type Yoyo can be divided into three types according to its different structures, namely integral shape, bearing type and clutch type, different types of yoyo have different properties and are suitable for a variety of different ways to play.

Integral type: The structure is the simplest, the whole cannot be separated, the time is very fast, the most suitable for ring play, can make a very beautiful, chic "thunderball", "turn three blows" and other gameplay. Suitable for beginners.

Bearing type: including wooden bearings, nylon bearings and ball bearings, the whole can be separated, the rope is set on the bearing, and it can be idle for a long time. It is suitable for rope play, sleep play, and can be used as a variety of fascinating techniques such as "sky tornado, wind and clouds".

It is suitable for intermediate and advanced players.

Nylon bearings reduce friction and extend idle time. The reason is that a nylon bearing is installed on the metal shaft, and the rope is sleeved in the groove of the nylon bearing, and the friction between the rope and the shaft is replaced by a lower sliding friction between the bearing and the metal shaft, and the resistance is reduced, so the idling time can be extended by 2-3 times. The secret of the longer idling time of the ball bearing lies in the fact that it is equipped with a plurality of small steel balls that can roll flexibly and have a small mating gap between the inner and outer shafts, and the inner and outer bearings can rotate smoothly through the rolling of the small steel balls (that is, the rolling friction replaces the general sliding friction), effectively reducing the frictional resistance.

Clutch type: can realize the automatic return of Yoyo, this is the use of Yoyo centrifugal force of the clutch, in high-speed rotation, the metal ball by centrifugal force, so that the clutch opens, become idling state, deceleration, because the spring force is greater than centrifugal force, the clutch is closed, fixed bearing. Suitable for ring and sleep play.

It is suitable for beginners and intermediates.

I wish you a speedy success!! Lookout lord, typing is not easy)

Go directly to the manufacturer to match one, or buy it online, and then use other yo-yos. You can also wash the shaft first, adding plenty of lube! Or maybe it's just a rope jam.

Hello, remove the bearing from the yo-yo, then pinch the shaft with your fingers, quickly toggle the outer ring, listen carefully with your ears, if there is an unstable noise or you can't pluck at all, then it is time to replace the bearing.

If the rotation time is short and the sound is loud, then the bearing is broken.

If you don't want to buy it, you can find a yo-yo ball bearing of the same type to change.

How to change the bearing: clamp it with pliers, slowly rotate the hemisphere, and the bearing can come down. Or twist the bottom bracket (that is, the rod with a spiral) first, close the two hemispheres, and then pull it out hard, and the bearing will have one side cocked, and you can easily remove it.

These two do not hurt the bearing.

Types of bearings: 1. Flat shaft 2, KK shaft (8 beads and 10 beads) 3. Ceramic ball bearings (balls are ceramic) 4. Special ball bearings.

The bearing is broken, it doesn't turn smoothly, and there is noise.

Wouldn't it be okay to just change one, change it to a better one, such as a ceramic or something.

Because in order to prevent rust, the bearings are coated with maintenance oil, which is sticky, which will hinder the rotation of the steel balls.

You can notice that the newly bought yo-yo is very quiet when sleeping, and this is because the oil film inside the bearing protects the steel ball.

But after playing for a long time, the bearing will be caught in dust and become less smooth. If you wash off the oil inside the bearing with a cleaning agent, the rotation of the ball will be extremely smooth, and you will hear the smooth sound of the yo-yo while sleeping. A yo-yo with washed bearings idling lasts a lot longer than a new one.

Volatile solvents, such as kerosene and lighter oil, should be used to wash bearings. Put the bearing into a vial containing the solvent, shake it gently and remove it with tweezers, and the oil will evaporate with the solvent after drying.

There is anti-rust oil before leaving the factory, and the idling is strong after washing.

If I do not wash it, I cannot fully exert the performance.

Strong idling after washing, to prevent rust, low sound.

Because if the bearing is not washed for a long time, it will not last long.
