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.

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)

@Proud2bmodest3 жыл бұрын
A tap should be run in the bolt holes to clean the threads which would make it easier to tighten the bolts.
@rooftopvoter30153 жыл бұрын
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.

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 😂🤣😂🤣

@black666bull93 жыл бұрын
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..... :)

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.

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
@5pm1773 жыл бұрын
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
