Hello from the Ozone, I am not listening but I can read.

I see we have thirteen pages and many views expressed. What we need is someone to answer the following questions so that we, who may have picked up somethings usefull and somethings stupid, understand the facts on bearing selection.

1, The effect of Load on the RPM rating of a bearing.
2, What material should the bearing be? St.Steel, Steel, Ceramic, or
Ceramic Hybrid
3, What is the difference between a seal and a shield? (No, one of them
does not live in the sea)
4, Seal (or shield) material
5, Oil or grease? (simple question)
6, Cage material?
7, Bearing tolerance class required and why?
8, The effect of bore and shaft hole sizes on fits?
9, If we have a slightly smaller bearing, that runs faster can we use it?
If so why?
10, If we had more ***** (no comments please) in the bearing, would that
would that be better or worse? and why?
11, What specification for a bearing would suit this problem? I suggest
an off the shelf bearing? Anyone who has custom parts made knows
the cost.

Simple Eh?
