this is the best video about bearing I am designing a machine now and this video save me thanks bro Keep the good work & i am waiting for your next video
Actually this is good lecture series brother. As an Engineer, this is very helpfull for me also. And, keep it up. Do more designs series. Thank you so much.
p = 3 for ball bearing and 3,33 for roller bearing because the balls in the ball bearing have a point contact and the rollers in a roller bearing have a line contact, so they wear less quickly :) Thank you so much for your video's, they are so well made and thus easy to understand! :)
@@mastermechanicaldesign ChatGPT says: Why p=3 for Ball Bearings: Ball bearings use point contact between the rolling elements and the raceways. Due to this point contact, the stress concentration is higher, but the load is distributed over a smaller area. The load-life exponent p=3 reflects the characteristic way in which ball bearings fail as a result of this point contact. Essentially, the life of ball bearings decreases at a rate proportional to the cube of the load. Why p=3.33 for Roller Bearings: Roller bearings use line contact between the rolling elements and the raceways. This line contact allows roller bearings to handle higher loads compared to ball bearings for the same size, but the stress distribution is different due to the line contact. The exponent p=3.33 (or sometimes rounded to p=10/3) reflects the slightly different load-life relationship in roller bearings due to the line contact nature, where the bearing life decreases less sharply with load compared to ball bearings.
Very nice explained sir. Also please make the vedio on selection of sprocket and chain from catalogue with calculation and with example and also design of a shaft or deflection of shaft under load
First of all thank you sir, Making this video very useful for me. And I am also watching the GD&T lecture. Kindly share the study material of those video.
sir sir you are a pain killer for student who get pain by reading books because in book all things are like a story but you made a visual film of that story what a talent sir my love from deep of heart
sir please make a video series on welding symbols, how we can apply in drawing and please explain selection, stress, strength and another things which is very important for welding & welding symbols👍👍👍👍👍👍
@@mastermechanicaldesign Don't supply readymade(your thoughts) material free of cost. Already you had explained that u are also seeing AI effect on CAD[That PDF and excel sheet is nothing but part of Artificial Intelligence]. Other words Automation is nothing but making people more Lazy😀.
@@sachinkapatkar I have given honest feedback. I have already made excel as per explaination. But i wanted to help @mastermechanicaldesign to improve the quailty of contents so thar more number of view he can get. Its not about laziness its about helping others.
many thanks for your simple explanation. please i searched for video about permanent deformation of bearing due to sudden load but for sorry i can`t get it, please mentioning it to me will be appreciated.🤜
Thanks for the video. Why you have not included the bearing block and coupling weight (load) while calculating the total load on the shaft? In video you have only considered the load of shaft (5Kg) and load of pulley (5 Kg). so, why you did not considered the weight of other parts? Thanks
Hi, In general, bearing block weight and coupling weight are negligible, no need to consider in case of bearing life calculation, (but we can consider, here I had not considered because, I try to make calculations simple, otherwise video will become too long, No such technical reason)
Thanks for your kind reply. But if we consider the weights of bearing block and coupling too, then which formula would we use to calculate the total weight on bearing? Please let me know. Thanks in advance.
Sir can you please do a video of example manual calculation for selecting the LM guide block ,,i saw your video but online tool sepection process only there , 2 days im trying to get from online source but i could not get still a confidence on that calculation.
Its completely dependent on the machine. What are the elements we are using in that machine. For example motors, pneumatics, hydraulics, ball screws etc. and every element selection should be based on calculations, to optimise the cost of machine. also to make sure that your designed machine will last long without any major breakdown for at least for 10 years.
For different types of bearing.. axial load capacity would be completely different. Like for single row angular contact bearings, we can apply heavy axial load, depending on how bearings are arranged. Moreover you don't need to check axial load capacity for these bearings which are specially designed for axial load carrying. You can directly calculate the bearing life. Axial and radial load capacity will be treated equally. But bearings like cylindrical roller bearings, we should not apply any amount of axial load. We should check the axial load capacity specially in deep groove ball bearings only. Because this bearing is mainly designed for radial load but could take some amount of axial load as well. Which one fourth of radial load
Very nice video... But constant switching of frames from person to sheet/calc screen is annoying... Not able to fully read the page... Try picture in picture type... Or presentation style with a web camera video at one corner...
i think teaching is not your profession but Passion because i think you made for that.
I love this style
this is the best video about bearing
I am designing a machine now and this video save me thanks bro

I saw this video 3 times for deeply understand, and may be infutre many time :D. Thanks so much.
You're very welcome!
Dear sir,
Thank you for explaining in easy way. It is very help full to up scale my self in my professional life.
You are most welcome!! My pleasure
omg this is another banger! i'm literally watching all your vids with my breakfast every morning!

Lots of information as usual ❤❤
I'm so glad 😊
Great🎉 thanks sir
Most welcome 😊
Though I am not an engineer, but I liked your explanation and presentation.... My best wishes to you...😊❤
Thank you so much 😊
Please make the videos of shaft design and also calculate the strength and failure value of shaft
Okay, noted!
Yes I agree with this, please make video on shaft design calculations as per multiple loading conditions and failure criterion m
@28:20 its ~195Kg. Please make Flow chart for easy understanding and Excel sheet of calculation, so that we can directly use in while calculating.
Sure, Just give me some time, I'll provide detailed PDF and excel sheets

Good video
Sir can you make an video upon how to select shaft material
Yeah, in machine design, we usually select EN8, MS or EN24
Shaft material should be tough, depending on size and stress
many thanks for your simple explanation.
please i searched for video about permanent deformation of bearing due to sudden load but for sorry i can`t get it, please mentioning it to me will be appreciated.🤜
Bearing sizing for sudden loading condition is coming soon
waiting for it.👌@@mastermechanicaldesign
Sir Please continue this series
Sure!!

Sir,
Please make a video on steel grade and their selection😢
Sure, Noted !!
PLEASE CREATE A VIDEO ON SPRING SELECTION PROCESS.
Sure!!
thank u brother
You're welcome!
which calculations are required for any machine design
Its completely dependent on the machine. What are the elements we are using in that machine. For example motors, pneumatics, hydraulics, ball screws etc. and every element selection should be based on calculations, to optimise the cost of machine. also to make sure that your designed machine will last long without any major breakdown for at least for 10 years.
Thank you sir ❤
Thanks for the great and useful information. not important but is not 1.95KN equal to 195Kg, not 19.5Kg?!
My bad
@28:20 what will be the formula if we are using different series for checking axial load capacity check?
For different types of bearing.. axial load capacity would be completely different. Like for single row angular contact bearings, we can apply heavy axial load, depending on how bearings are arranged. Moreover you don't need to check axial load capacity for these bearings which are specially designed for axial load carrying. You can directly calculate the bearing life.

Because this bearing is mainly designed for radial load but could take some amount of axial load as well. Which one fourth of radial load
test tomorrow, help a lot😂
at 30:55 it should be 195 kg, btw good explanation but little confusing
Very nice video... But constant switching of frames from person to sheet/calc screen is annoying... Not able to fully read the page... Try picture in picture type... Or presentation style with a web camera video at one corner...
Heat treatment process type
How to deside HRC value
Very good suggestion 😊
Sir GD&T series start kijiye
Very soon
How can I calculate Fa and Fr?
Hahaha, that's the input, it might be a weight or belt tension, or from whatever application you are doing.
Sir if possible give hole calculation of this problem
Share it in the form of pdf atleast
Sure
😍😍👍👍👍👌
Thank you
⭐⭐⭐⭐⭐
that L10 formula seems strange to me. accordign to that formula, the faster the rotation, the longer the life. Isn't that unreasonable in real life?
Sir, you're a legend. That's all I gotta say 🫡
