Q:are bearings Dust Cover unique for specific wheel/hubs?
Wheel Dust Covers
Q:what are cylindrical roller bearings?
You answered your own question.
Q:Are bearings measured in diameter or circumference?
Neither one. Bearings are measured in degrees. Or, do you mean bearings as in ball bearings? Those are measured in diameter.
Q:I forget hot to change the bearing s in my hockey skates, and what skates/bearings would be best for missions?

Q:what kind of bearings go in a bmx rear hub?
They are probably 1/4 or 5/32 diameter balls, but the rest of your question leaves me wondering. The hubs that your bike has are quite OK for the grade of bike you have, and just replacing the bearings will have no effect- or if anything a negative effect- on the operation of the hub. Keep in mind that the bearings run on cups pressed into the hub and on cones that are threaded onto the axle, so replacing bearings on a new bike without upgrading these items is useless. By the way, my guess is that the cups and cones can't be upgraded. I suggest that you leave what seems to be a brand new bike alone and stop trying to improve on something that doesn't need it. If you have some problems, see you dealer and explain it to them- chances are any adjustments will be free (or cheap).
Q:my new skateboard bearings are stiff?
spray a little dwi 3 oil on them.
Q:Which Skateboard Bearings Are Faster, Bones REDS or Rush Abec-7 bearings?
There is no way for someone to give you an answer to your question without testing both bearings on expensive equipment with specific loading. If the Rush bearings work better for you, buy them in the future. However both the shop guy and jibiking are full of nonsense about ABEC and also partly right. ABEC is a tolerance specification for how gaps inside the bearing and how much it can wobble when it spins. It has nothing to do with how easily a bearing spins. ABEC got used for skate bearings because companies were using Precision grade bearings which are garbage. ABEC 1 rated bearings were a vast improvement over the Precision grade. Bearing sellers then decided if 1 is good, larger numbers can be advertised as better. A few of the better bearing companies (Twin Cam, Zero Drag, Bones) have designs that are better for skating by not meeting the specifications of the ABEC ratings..
Q:What does ABEC for skateboard bearings mean?
Sometimes the higher the number doesnt mean anything. You can get some ABEC3 that are just as good as ACEC 7. Like REDS for instance there like 13 dollars and they perform and last just as long as a pair that costs like 25 dollars.
Q:Difference between rubbing bearings and roller element bearings?
With roller bearings there are small rollers between the moving and non-moving part so that there would theoretically be no friction. Ball bearings work in a similar way.
Q:can i install crankshaft bearings without taking the crank out if so? how?
No,the bearings need to come out so you can first clean the crank journal and second measure the dia.of the journal on the crank and the block to see if you have any wear and what size bearing to go back together with,either standard or an oversize bearing.
