There are often some novices to ask; about the problem of changing bearings; is it faster than -5? Still -7 fast? Novices will also blindly worship some of the ceramic bearings; what I will clarify here is that in fact, many aspects of bearing demand can be recognized as suitable for the individual.
Novice Mistakes 1: Do not think about the characteristics of the small initiative; blindly pick me to 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 come over; It can't be used. 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 not three months, this set of bearings is basically scrapped. So you practice The direction of the move; the resolution you use the bearing; the faster the bearing; you use the limit small wheel; how fast can he?
Novice Mistake 2: I think the -7--5 fast novices 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; because the SKF specification has always been Rejecting the concept of ABEC; the reason is that this norm has never clarified the material; nor has it clarified the layout of the lubricants and supports used. From this point of view, the -7--5 that the novices admire is unreliable; I The C3 that used to be -5 is faster than the -7 of domestic shoes. Because his material is different; the brackets are different; the lubricants are used differently; so the good-5 is faster than -7. .
Novice Mistakes 3: I think ilq-96 beads are not strong. This is also the location of my misunderstanding; but I 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)
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 who can do it for me; a set of good black pottery is destroyed; it can be seen that ceramic bearings are definitely not suitable for some measures; therefore, it is here to persuade that there are plans to learn the limits; FSK Brother; don't pick ceramic bearings.
Novice Mistakes 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 have seen people use Harbin black cover industrial bearing brother; the role is good; we have a good evaluation together. It can be seen; professional roller bearings can not be compared with industrial bearings.
I am here to make a simple variety distinction:
General training brush street does not contain running jump; slide and other initiatives (general people): general ABEC-7 meets the favorite brush street; love speed; love flat flowers; also play slide also run and jump (fsk strength players): at most Ilq-9 iron cover; steel bracket bearing.
Love flat flowers; love to brush the street (flat flower player; non-explosive player): il-9 iron cover just bracket; some time bearings are too fast;
The other players in the limit class: 5 meets; the good-3 in foreign countries is not bad.
Speed ​​skating: single-sided dustproof; ceramic bearings; speed skating is not afraid.
