Why Faster Bearings?

Graphite is a conductor...

A good conductor, but you lost me a little with where you are going with that.

[tomustang]

It won't work with graphite or plastic spools - only spools that can conduct electricity.

I do not know much about it, so maybe someone can add their thoughts.  I seem to remember something I read that said because of the way graphite fibers were suspended in resins it created a high resistance to eddy currents.     Eddy current as I understand it is the  counter EMF required to produce the braking effect with magnetic brakes in fishing reels.  So with a high resistance to the production of eddy currents you would get little to no braking.  

 

Again, this is just how I understand it.  I also understand that graphite conducts electricity much differently than metals such as copper and tin.  This may also play a part in this.

So why not use 304SS or 316SS?

Too soft. 440 is also used in things like sword blades and is very hard stainless. 304 or 316 would offer good corrosion resistance but would likely scuff, scratch and generally degrade to replacement much faster. This is also why ceramic is a nice choice albeit noisier.

316 is very soft compared to 440, it also can not be machined to the same tolerances that 440 can, which makes it a poor choice for precision bearings.   If they would run the 440ss through a passivation process to help remove impurities the corrosion properties would be better also.  This may be what they advertise as ARB, CRBB bearings.

The balls in a ceramic hybrid bearing are rounder, harder, smoother and lighter than ss in addition to corrosion proof. Easier startup is critical for finesse casting, but still beneficial for heavier weights. Resulting Improved accuracy is the biggest benefit with distance a happy coincidence. There are more cost effective methods to achieve the goal than making bearing replacement the first resort.

I am not going to quote the whole post above me. As for it when it's most effective and that it would be at a higher rpm I will give a easy example. So say you have a giant magnet that was strong enough to move your car. If you go blowing by the magnet at 120 mph how much do you think the magnet would change anything. Now imagine going past the same magnet at 5 mph. That's the best way I suppose I can explain it to make sense.

So in a fishing reel, particularly the spool, what do the magnets act on.   In your example, the magnet works on the car because it is made of steel, and there is a magnetic attraction.  In a fishing reel, the spool is made of aluminum, so what do the magnets act upon?

It still acts on the aluminum, it doesn't have to be a ferrous material to induce a current. http://en.wikipedia.org/wiki/Lenz%27s_lawThe change in the state of original magnetic flux due to the spool spinning naturally creates a EMF that acts opposite of the change, thus magnetic breaking.

Thanks for sharing that

Detour: are ceramic bearings noisier? (I heard they are)

[Delaware Valley Tackle]

Ceramics are a little louder, but I don't find them to be the growling monsters that some do. lol 

 

I look at like it hot rodding a car or bike. Faster almost always means louder to some degree, and to be honest, stock is probably fast enough anyway.

[kcdinkerz]

It sounds cool swooooshhh. Lol easier to cast with I don't see Much improvement in distance only when I'm throw light stuff on my ch50s do I notice further cast. and I would not reccomend ceramics if your thumb controll is Not good. Backlash are nasty

They are certainly noticeably louder in Magnesium framed reels.

Do you mind sharing the brand and spec you used? Also, did you clean the reel at the same time? Reason I ask is that I see where factories grease the frame to quiet the spool and after cleaning the spool can be louder as well.

Back to breaking: your discussion seems most centered on fixed inductor's while there are springs and lateral movement of the inductor in most spools.

What are you getting at John?

You never want to stir up a guy with a name like Angry John.   I assure you that was not my intent.

The discussion about mag working only at low speed most does not work with variable inductors. They brake most at high speed because the mag influence is high and the inductor is deepest in the magnets.

From what I can tell of the math behind Lentz's Law it looks like the EMF produced is proportional and inverse of the speed of the inductor, meaning that the braking would be very linear throughout the cast.   The difference that comes to mind is that centrifugal brakes make physical contact with a braking surface and probably have a more profound effect than the magnetic brakes at the same time.  When the spool speed slows and the centrifugal brakes are less effective then the effects of the magnetic brakes are more dominant.

 

These are just my thoughts

[Angry John]

That matches with my on the water observations. I have not used but one centrifugal reel my Luna 300l so I would consider my observations lacking in that style of braking system. I believe most people stick with what they learn on and call it best. Both systems have to work well or one would be gone by now.
