The life calculation method described in this video has been developed in the 1940s. The basic rating life was the very first life model, and it has later been enhanced with e.g. the effect of lubricant or contamination. It should be clearly stated that this is only a very rough estimate for calculation bearing life! More advance models should be used to do a more realistic calculation, reflecting more of the application conditions
I have a bearing in a transmission that, when it fails, ruins the torque converter. It is a ball, and I wonder if a barrel roller bearing would do better. I just wonder if barrel type can run 1000 to 2500 rpm.
we know, FL^(1/a) = constant. But in the last example, 9:03 - 9:31 , using desired value, we get, for bearing A , FL^(1/a) = 92605.83 for bearing B , FL^(1/a) = 138908.75 how can we choose load and desired life independently ? [ But F & L are no independent] or how is it possible for certain reliability the FL^(1/a) gives different value?
You are a good teacher mate
Thank you, you made my life easy
Excellent videos overall. God bless.
Kindly note that at 6:06 I heard "...to select a gear...". I hope it is worth mentioning.
Thank you, simple & easy to comprehend. keep it coming..
I really thank you, what you are doing is really important keep creating awesome content like this !!!!!!!
absolute life saver
Content is quite easy to understand and helpful 👍
Beautiful explanation mate
Thanks a lot, So quick to understand, Beautifully explained,
I love this video. Very very informative. Thanks for explaining so well.
Thank you!
amazing explenation, so easy to follow and visualize with the videos, thank you so much!!!!

where do you find the more recent, "advanced" models?
Adding journal bearing topic would be great
It helped me a lot. Thanks💜
Just amazing!
thanks, good videos for solidfying the concepts, liked.
SOO COOL
Legendary stuff
Didn't think i'd be learning bearing selection from Mario's F.L.U.D.D.

Sir, the answers at the end of this video of C10 for 200 lbs and c10 for 300 lbs, seems to be incorrect.
What the software creat a presentantion and drawing the bearings??
Can anyone calculate the life of NU236 C3 UNDER 992 RPM?

Please include with translate🙏
How do I do this?
@@LessBoringLectures English translate it’s okay. I confused when i listen it, maybe with translate little bit helpful 😁 you speak too fast hehe
