What Size Of Bearings Are For Roller Skates?

Roller skating is becoming more and more popular among young people in China. For roller skating enthusiasts, a good pair of roller skates is very important.  But a pair of good roller skates also need to maintain their own shoes, otherwise a pair of good shoes will greatly reduce life. 

Working principle:

The principle of the wheel hardness determines the size of resistance, the size of the wheel determines the speed of the speed, the material of the shock absorber determines the quality of shock absorption, so the harder the wheel resistance is smaller, the larger the wheel speed is faster, the wider the wheel grip is stronger, the better the material of the shock absorber is lighter.

• 1. First of all, if you need to replace a new wheel: how to confirm the size, as shown in the picture, look at the front of the wheel: Generally, the size of the wheel is 72mm, 76mm, 80mm, generally 39 yards as the cut-off point:  Size 39 and below are 72mm/76mm, size 39 and above are 76mm/80mm, of course, there are flat wheels are the same size wheels.  
• 2. After selecting the wheel, the next step is to change the wheel and find the nail hole as shown in the figure below:  And own roller skating wrench, such as nail, must be fully inserted, otherwise easy to slide wire, at the same time due to play a long time may be more tight, then the most important is the direction of the force, be sure to conveniently unscrewed the nail, don’t stop the strength twist, causing tool to bend or break so easily, remember!  
• 3, the next is to unload the bearing, with the wheel slide wrench head against the bearing ring between the two bearings of the saucer position, remember that it is the ring, directly two hands, or use the principle of leverage can knock out, this depends on personal habits, as long as it does not damage the bearing!  

• 4.Bearing installation time is tight, not easy to install, so a good way to share: put the bearing on the wheel center hole position alignment, and then put the roller skating wrench flat on the bearing, a little hard to hit down the wrench is ok, it doesn’t hurt all bearing, if you go in bearing can be directly with the hand press is unnecessary in this way.

• 5, the next is to install the wheels: in the same way, the wrench must be aligned with the nail, and completely inserted to avoid sliding wire, more important is not to twist too tight, twist almost the same time, roll the wheels by hand to see if it turns smoothly, the wheels are generally printed toward the outside, the middle is big, small on both sides!  

How to maintain roller skates bearings：

Bearing is an important part of roller skates, equivalent to the engine of a car, good shoes, how fast, in fact, and bearing have a direct relationship.  So roller skating players usually also pay great attention to the maintenance of bearings.

One roller skates bearing maintenance method

Use stain removal oil to wash the dirty things, and then use lubricating oil to maintain, if you do not use lubricating oil, it will rust faster after soaking in the past stain oil.

You can remove the cover of one side of the bearing and wash it with detergent oil (15 yuan/bottle at the gas station). After washing and oiling, you can use needle oil.

If the oil is too sticky, add a little WD-40.

But rainy day skating is taboo, bearing will rust destroyed.

Bearings stained with water must be oiled immediately maintenance.

Second the appliance：

Lubricant: protection of bearings; Remove dirt and foreign matter in pelin.

If the bearing does not rotate properly and there is noise, it may be the bearing entering sand.

If you are not very particular about it or lazy, in fact, you can do without it. Moreover, once the bearing is removed and the original thick butter is washed, it will become easier to sand than the original, and it will be more often washed later.

Three equipment:

Two cans of detergent oil, bowls or other containers; Precision driver; Toothbrush. Lubricating oil;

Four Steps: 

• 1. First of all, when our roller skates play for a period of time, we should remove all the bearings and soak the bearings with diesel or kerosene for cleaning. If there are technical conditions, it is best to open the seal cover for cleaning, and dry the cleaning oil after cleaning.
• 2, secondly, after cleaning the roller skates bearing, we have to test the flexibility of the bearing. Can be directly mounted on the wheel above the test, hand toggle the bearing to run quickly, listen carefully to the sound of bearing rotation, mainly to listen to the squeaky noise!
• 3. Lubricate the roller skates with grease, soak the roller skates in the heated grease until there is no bubble overflow, remove the bearing, then wipe the grease outside the bearing with a soft cloth, and reinstall the bearing on the pulley.
• 4, fixed bearing after the lateral dial, check whether the bearing wear loose phenomenon, loosening serious, if the second step after rotation issued too much noise, there is a serious defect of the bearing is necessary to remove it to replace the new!

 The above is the more basic maintenance steps of roller skates bearing, every once in a while to maintain such a time, so that you can prolong the service life of your bearing.
