Inline Skate Vs
What's the Deal?
Now when you
strap the skates on, and go skating are you Rollerblading? or
Inline Skating?……… Well, again Rollerblading is an incorrect
usage of a name, not a verb, so you can’t use the term
Rollerblading to describe what you are doing. The correct
term is inline skating, I may be wearing
but my action is inline skating..Continued

Everything You Wanted To Know About
Skate Bearings But
Were Afraid To Ask
The inner and outer race (made from steel).
The balls (generally made from steel).
The cage (made from different materials including nylon, plastic and steel, to keep the balls spaced properly around the bearing).
The shields (which act to keep the dirt and dust (or in the case of the speed skaters, road kill out of the bearings).
"The ball bearings we use
in our skates are made up of several parts and pieces:
What about ABEC
When all levels of ABEC are made with the same standard of
quality, a ball-bearing in an ABEC 5 will spin faster because it has less room to move
laterally, thus all it's energy is propelled forward. The unfortunate part is that not all
bearings are made to a high standard. It is all a matter of quality. The better bearings
are made perfectly round and smooth. The races and bearings in a good skate are honed and
polished two or three times. In cheap bearings, the ball-bearings are very rough with many
imperfections. There are other factors but it becomes more complicated. Just remember that
if you purchase a skate with a good quality bearing you will roll along just fine. To
illustrate this, one of the fastest consumer level bearings on the market is the Boss
Swiss Bearing which is not even rated. Industry experts say it is probably an ABEC one or
three. Racers will often use ABEC 1 bearings in their skates (these would sell for $160
My mate's bearings spin longer - are they better?
By Duncan Clarke
The simple answer is "Not
necessarily". Let me explain.
The difference between spinning the wheel and seeing how long
it takes to stop and actually using the bearings during skating is the loading on the
bearings. When you are skating, there is a lot of force from all of your weight on those
bearings. When you hold the skate up, the only load is the weight of 1 wheel.
Testing how well the bearings perform with no load will not
tell you anything about how well they will perform loaded. Try this (or at least think
Build a flat bank that can be made steeper and shallower
Put a pencil on the bank, it's axis perpendicular to the slope
Raise the bank until the pencil rolls down the bank, and note
Cover a ball-bearing with grease and repeat steps 1 to 3
Which do you think will need the steeper slope? This is the
one that would spin longer unloaded. Which do you think would roll better with 80kg on it?
That is the one that would make a better bearing.
Basically, the resistance caused by lubricant is unaffected
by the load on the bearing. The resistance caused by irregularities in the bearing surface
will increase with the load. As such, with no load; lubricant drag is the dominant force
whereas with a large load surface quality is dominant.
This is why the spin test is of no use at all in determining
how well the bearings will perform when you are skating.
