Novice Misunderstanding 1: Do not think about the characteristics of the small initiative; blindly choose I remember that I used to have a hot brain; I grabbed a black ceramic bearing from my brother's hand; ceramic. I feel very cool; but if I really want to take it over I can't use it. Although the ceramic bearing can avoid the removal; the speed is fast; but he can't stand me like this person; FSK original is the direction of the action of destroying the shoes; the result is no more than three months, this set of bearings is basically scrapped. So the direction of your practice; the resolution you use the bearing; the faster the bearing; you use the limit small wheel; how fast can he?
Novice Mistake 2: Think -7 is faster than -5 Newcomers often have the misunderstanding; -7 is faster than -5; this is actually a big misunderstanding. -7-5 in the bearing specification is only about accuracy; The SKF specification has always rejected the concept of ABEC; the reason is that this norm has not clarified the material; nor has it stated the layout of the lubricating oil and the bracket used. From this point of view, the -7--5 that the novices admire is too fast to rely on. The C3 I used was -5 is faster than the domestic shoes -7. Because his material is different; the brackets are different; the lubricant is used differently; so the good -5 is better than - 7 quick.
Novice Mistakes 3: I think ILQ-96 beads are not strong. This is also the location of my misunderstanding; but I have used the iron cover ILQ-9; there is no doubt about it; even my 190 kg FSK players can accept; are you worried about me? But my personal opinion is if you are a FSK player; try to choose iron steel; steel bracket ILQ-9; do not choose nylon bracket; nylon bracket although the speed is increased; but will reduce the acceptance.
Novice Mistakes 4: Bearing Clearance with WD40 (Carbure Remover; Maybe Gasoline)
ã€€ã€€ Novices often use high corrosive carburetor scavengers and gasoline to remove the bearings of the ego; this actually destroys the bearings of the ego. The reason is that these two materials are due to the high corrosive removal. Such removal; Although it is very clean; but it will also destroy the brackets and steel balls; there will be a tendency to break in the evening; therefore, I do not advocate the use of these two materials to remove the bearings.
Novice Mistakes 5: Ceramic Bearings Can Be Used by Anyone I can do it with my own small ones; a set of good black pottery is destroyed like this; it can be seen that ceramic bearings are definitely not suitable for some measures; FSK brothers; do not pick ceramic bearings.
Novice Misunderstanding 6: Industrial bearings and roller bearings are not the same This is a fault; I have seen a bunch of people using industrial bearings; the role is appropriate. Industrial bearings are not slow; and also very robust. I see The brothers who used Harbin black cover industrial bearings; the role is good; we have a good evaluation together. It is thus visible; professional roller bearings may not be comparable to industrial bearings.
