what is the difference between a ball bearing and a regular ceramic pulley?

The difference is ball bearing, or (cartridge bearing) is the outer race is pressed into the pulley and the inner race rotates and is held in place with steel balls. Ceramic is similar, as the outer race is pressed into the pulley, but the inner race is machined to a close fit and rotates inside the outer race. All ceramic bushings I have seen are white, and look like white plastic, but is very hard. The actual pulley function is not affected by the type of bearing.

Standard bearings are made of steel and will eventually wear and form pits resulting from dirt getting through the bearing seals. Ceramic bearings (which are more expensive) last longer and tend to run marginally smoother. Unless you're a racer where every little bit counts, ceramic isn't terribly necessary for pulleys. They are much more beneficial in the wheels and bottom bracket.

Durability and weight. However, I usually find the nylon pulley wheels wear before the bearing condition really matters.

I believe it is a metal bushing type of thing. I can't see any ball bearings. I went to the manufactures web site and if I had made it with ball bearings, I would have mentioned it. They did not. I can say that it is very well made and the peddle operation is very smooth. Even with tension applied it is consistent pressure. I am giving you the link to the manufacturer, I am sure your will be able to ask them about the ball bearings. Sorry I can't say for certain if it is or is not. http://www.battlecreekequipment.com/product_detail.cfm?pid=76

It does not matter from which material pulley made off. So metal would work just as good as plastic as long as you doing exercise.

There are probably a lot of technical differences in the tool and the capabilities, but the most basic difference is the shape of the domino/biscuit/dowel (whatever you want to call it). Unlike a traditional biscuit or dowel, the Festool Domino cannot rotate, twist, etc. So it gives you a totally different kind of joint. The festool videos on their site are excellent. It seems like every person I've spoken to or read about thinks the domino is the way to go.

Both where contracted to manufacture the FILBE at different times. I'm not sure of any difference.

The one i purchased did have the bearing it was pressed into the pulley already. mine worked great & was a quality oem part.

Bio balls are a whole different type of media...Ceramic rings are in theory the same type of media as this but the eheim has more surface area compared to the rings.

3 A-RB stainless ball bearings + 1 A-RB roller bearing. I just bought 2, one for a friend, but I have not had the chance to use it yet. Sure seems like a nice reel though. Looking forward to the first time out with it. I bought the Shimano Calcutta 400B for light to medium duty salt water fishing i.e. sheephead, calico bass, and what ever else bites at or under twenty lbs.

The pulley is probably the same. How its connected would be the issue. If it was me I would stick with shimano parts.

I am not sure as I gave it as a gift and didn't notice what type of balls were used. Hardware stores would have them if they are small steel balls.

I wondered the same thing. After checking out some other reviewers I think the ball bearing units overall were in better quality I think. Also someone mentioned something about sleeve bearings being mounted a certain way that would cause early failure or something of that nature. Either way i don't think it was a huge price difference extra for ball bearings. I'd get these again. They are good.

This is my rule of thumb so to speak, never put a bearing in a wheel hub that you do not have some form of the old bearing retainer, so that you match the ball bearing count"in this instance 7, there are also 6 ,8 and 9 count balls in axles of this kind which i assume has a 3/8 axle? , i eould purchase this bearing only if youve matched up the ball count and even inside and outside diameter of the retainer itself.

I've used both, it has more torque at the lower settings but is also heavier and gets hot faster.

Yes, like Tri said, it has one less ball bearing. It's pretty much the same otherwise. :)

They are both made by faber castel and I find absolutely no difference in the two. They both work beautifully plus these are cheaper which is nice:)

It is used to drive the new bearing in and align the coupler to the new bearing. It is not a puller.

I'm pretty sure it's the ball end. My review is a few years old but I'm pretty sure that was for my tool box which is a ball end.
