I worked for The Timken Rail Road Bearing division for 15 years and one of my jobs was the setting the lateral play with various widths of spacers ( we had stacks of them in 0.003” difference in thickness to get the bearing into the proper range) between the two cones. As I recall it had to be between 0.021” and 0.027”. That is what he was measuring with the mag base indicator. While the first bearing shown are not Timken it’s exactly like Timken. While the rollers look straight they are actually crowned, larger in the middle. Our lateral machine rotated the unit having all the pieces moving and seating therefore giving a very accurate amount of play between the top cone and the bottom cone. The Columbus OH plant did the screw machine turning, heat treating, grinding, quality control inspection at all stages, and assembly. The rollers came in as long round bars of stock and they were fed into a machine sheared to length then slammed and pressed into a die to indent the end and give them the tapered shape. They were then heat treated then ground the the smoothness and crowned shave that was necessary, each piece visually inspected. The grinding operations consisted of 6 or 7 machined that had a steel guide about 20” in diameter that had spiral shoulders and it rotated moving the roller past a rotating grinding wheel with coolant flowing to wash away the grinding dust, this was repeated through the other grinding stations, each on grinding a little off and shaping the surface to a crown. That is but a small segment of the precision manufacturing process.
In my youth I worked at FSA, Full Steam Ahead in california. I had the pleasure of rebuilding these bearings and end caps. Wish I stayed there. This is a small operation compared to FSA. We had bearings come in and after we disassembled them some where missing multiple bearings and a few had no cages.
Very helpful; thank you for publishing your instructive video. I would like to have seen the exemplar photos/illustrations of false brinelling against which the rollers/raceways were being compared.
At 10:30 min. When you checked roundness of cup in your gauge. At that time you should use Ground V block in place of rotational shaft. (You can avoid radial runout of bearing which support rotational shaft)
Bottom tap run into the holes and blow that crap out with low pressure air. Too much effort required to get that bolt to snug up and that means there is crap on the threads. Hate that.
As per RDSO guide line G-81 manual total work should be done in dust proof area.calibration schedule of instrument & gauges are mentioned.washing medium what?? If kerosin oil used ,where rust preventive oil.
This is just possible in 3rd world country's, where the weekly loan is like 30 to 50 Buck's. Even when this bearing cost's 500 Buck's, it is not economical in "modern" 1st World Country's. I would say at least 8 to 10 Hour's work is in there, maybe im wrong... but let's say 10h, 10h x 30 Buck's for the Worker, 100 to 200 for the Machines(tester,measurment,etc....) then you are at 400-500 Buck's..... in other Word's at India it's economical in 1st World Country's not..... :)
@Bulldozer Im aware that the throwaway world is not good, everything that i can repair i repair. But when the cost of rebuying is lower then the cost of a repair, why would i spend that extra Money.....
Talking about India, do you know what part is it. Its a bearing of a railway coach. India has the largest network of Railway compared to any developed country and of course the busiest of all. No compare this, only in Mumbai, we have 1 train between every 3mins. And this is just an example.of 1 city. So before commenting shit, first do some research.
hi i am m.rama kumar working as technician-1 in diesel loco shed , visakhapatnam, east coast railway . i want know ctrb fitting and its measurements between inner race and ctrb of wdg4 and wdg4d locomotives please suggest and send videos or any ctrb maintenance manuals and send any online links
One guy his shoe laces are untied, and he’s just walking all over them, and flopping around everywhere, ready to get caught in something, and yank his foot into a machine. The other guy his are missing completely, so it looks like that’s already happened, but he got lucky, and it just ate the laces and not his whole foot. I bet OSHA would have a field day in India lol 😂🤣😂🤣
Please, I am from Egypt and have been searching for a long time for a ball bearing or something similar to install it for a handmade body that rotates at a speed of one million revolutions per minute without being subjected to corrosion or something that works with electromagnetism. Please, is it possible for me to find something like this? Thank you very much
It seems to me that two people would not be capable of checking thousands of bearings this way I bet most of them don't get checked just cleaning and regrease
Yes,very sad indeed,see how the chap is bending to open nuts,can't they have suitable bench I think it is shop in charge who must provide all infrastructure. It would improve efficiency and productivity plus fatigue and accident minimised a lot.

What will be percentage in your roller of retained austenite ?
It is good to see workers with care and attention to a very important part of the rail system. Thanks for sharing.

please use air tools to mount and dismount the bolts. to increase speed of work.
Very nice! I like the technology!
A tap should be run in the bolt holes to clean the threads which would make it easier to tighten the bolts.
Bottom tap run into the holes and blow that crap out with low pressure air. Too much effort required to get that bolt to snug up and that means there is crap on the threads. Hate that.
Fantastic
Ausgezeichnet 👍👍👍👍👍👍
Me parece genial que reciclen en la medida de lo posible
Perfect video!
What are bearings cleaned with?
No visual inspection for pitting?
As per RDSO guide line G-81 manual total work should be done in dust proof area.calibration schedule of instrument & gauges are mentioned.washing medium what?? If kerosin oil used ,where rust preventive oil.
Need some more videos in this channel reg. workshop maintenances
Whats the cost of all that time and testing as opposed to renewing the bearing straight off?? Would be nice to know.

Ball bearing is impossible rotated at that speed. Most of bearing can’t. You can search for magnetic bearing and air bearing that may can help you

Why is that bearing dismantle press on the floor. Build a bench for it ffs.
Its like they are working in a third world country.
Ken C India...
All that precision work and not a torque wrench for the three bolts 🤨
Yes,very sad indeed,see how the chap is bending to open nuts,can't they have suitable bench
I think it is shop in charge who must provide all infrastructure. It would improve efficiency and productivity plus fatigue and accident minimised a lot.
Neasmani sithappa told us not use torque wrench
@@Loosu1 might be some tenable reason,love to know that.
Trained for this but can't due to health issues
Good job but roolar bearing moment not 99%.

Wrongly used of dial gauge or lateral end play
