Bearing type and size
The document form here: http://www.irdbalancing.com/downloads/techpaper1balqualityreqmts.pdf contains one of the best info that I missed, very valuable for me, I did not know about it, thank you for it. Let's consider the shaft/rotor is electrical driven by electromagnetic forces. These are...- viki2000

Bearing type and size
Then let me ask you opposite: what do you consider max. acceptable speed in RPM for such system with only one bearing (what type?) when the mass is distributed as follows: - the rotor is a 0.5Kg disk where the material is considered homogeneous and the cutting precision of the disk is 0.1mm.- viki2000

Bearing type and size
If it is of any help, I can consider the weight lower, down to 0.5Kg. We can consider also the radial forces that turns the shaft equal distributed around 360°, so not only one force from one side. We can imagine an AC squirrel motor where my shaft is the rotor, but only vertical position and...- viki2000

Bearing type and size
Please consider only 600RPM and 1KG, continuously run 24h. Imagine that plate is a stable heavy table and the bearing is well fixed in the top of the table. My pictures are only to get an idea of what I want, but is more theoretically, not the actually design. „As far as "lowest possible...- viki2000

Bearing type and size
Few more details. Before I asked the question here, I already searched the internet couple of days and I have read different info about the bearings. Then my head became bigger and the multitude and variation of info acquired started to be mixed up in my head resulting a salad. Nevertheless, I...- viki2000

Answers: @ AidanMc The radial bearing used in the picture is just an example. It may be any other type that you suggest. I just made a picture setup with photos from internet. At this stage there is no physical setup nor CAD drawing. I just gather info and I need to understand what would suit...- viki2000

Bearing type and size
Hi, Assuming I have a plate as below with a hole in which I install a bearing. Then I insert a shaft and in top of the shaft a weight. Let’s say is a round weight, can be a sphere or a disk. Questions: - What type of the bearing should I use? - From what material should be the bearing made? -...- viki2000
