The difference between ABEC-5 and ABEC-7 is that the size is different, the accuracy level is different, and the use is different.
1. Different sizes.
1. ABEC-5: The accuracy is relatively low, so the relative size will be relatively large.
2. ABEC-7: The accuracy is relatively high, so the relative size will be relatively small.
Second, the accuracy level is different.
1. ABEC-5: ABEC-5 is equivalent to P5 level of domestic accuracy level.
2. ABEC-7: ABEC-7 is equivalent to P4 in the domestic accuracy grade.
Third, the use is different.
1. ABEC-5: ABEC-5 is more suitable for ordinary street use, and the bearing is solid and durable.
2. ABEC-7: ABEC-7 is more suitable for professional tracks and has a long sliding distance.

The only difference between Skateboard Bearing-ABEC-5 and ABEC-7:
They have different accuracy classes, and ABEC-5 is equivalent to P5 of the domestic accuracy class. ABEC-7 is equivalent to P4 of the domestic accuracy class.
Skateboard bearings are not as precise as those of yoyos, because there are eight bearings and four middle locks on a plate, and it is best to replace all eight of the bearings, regardless of which shaft explodes first, this is necessary.

The difference between ABEC-5 and ABEC-7 of sliding plate bearings is that their accuracy levels are different, and ABEC-5 is equivalent to P5 of the domestic accuracy level. ABEC-7 is equivalent to P4 of the domestic accuracy class.
-
The higher the number, the more accurate it is, the more stable it is to slide, but the more susceptible it is to wear and tear.

Depending on the slide plate, the bearings are also different.
Generally, the whole plate is equipped with industrial bearings, and the side is printed with the appearance of ABCDE, and the slider is the best to use, with several types of bearings such as minilogo, bones, and superbones.
Slide bearings, 8 bearings, each wheel is equipped with 2 precision bearings. Bearings are available in different precision and durability. Generally, bearings have an ABEC designation, ranging from ABEC-1 (least precise) to ABEC-7 (most precise).
However, some bearings do not have the ABEC logo, such as the bones bearing has never been ABEC logo, and their BonesSwiss Ceramics is one of the best skateboard bearings.
The bearing structure includes: outer ring, inner ring, ball, cage, dust cap, lubricating oil. >>>More
NSK bearings are Japanese.
NSK bearing, NSK's main product is bearings, NSK bearing company, due to excellent quality and thoughtful service, NSK company's business is also making rapid progress.

Due to China's pivotal position, NSK's career development in China will further improve the quadrupole system. >>>More
Let's start by learning how to glide on the horizon before we think about jumping!
Now the bearings are very realistic, a large part of the situation you can not distinguish the real from the fake, only the bearing back to the factory for testing or ask a professional organization for testing, and then there is experience, some genuine goods you see more than a look, that is fake, or you fake you see more, see the appearance of this bearing is not bad, but do not be blinded by the appearance, to determine the quality of the bearing rest assured I concluded: >>>More
