Splitting Bearing To Avoid Equipment Disassembly
Splitting Bearing To Avoid Equipment Disassembly
(OP)
I have a machine tool with a column of about a foot in diameter. It requires an upper and lower tapered roller bearing and race. The pivot only rotates in and out 180 degrees in about 15 seconds and 3 times an hour. Load is less than 2 tons. Now the question-existing bearings are 20yrs old and looking at race surfaces need replaces-I want to edm 4 sets to make two perfectly fitting sets so I do not have to disassemble the machine tool and can replace the bearings. On one machine tool I see this has already been done.
Questions is/are-What are the pitfalls of doing this? Do I need to destroy 4 to make 2 or is leaving a small .006 gap from the edm wire okay? Thoughts/Comments.....

that full bearing can withstand. I do not think two
bearing sections from different bearings will have the
same geometry. Close is not good enough.

a bearing from a manufacturer.
We got a lot of our split bearings from FAG.

If you EDM the bearing, how do you plan on securing the two halves together? Split bearings are made with space for screws to reassemble the bearings, if you cut these bearings, you might not have any room to do this. Another problem with doing this yourself, the two halves might not match up well enough to provide a good running surface. Since this is low speed, a small gap between the two halves might not be a problem, but your life probably will be reduced.
Since the existing bearings lasted 20 years, I would bite the bullet now and do it right and get another 20 years out of the bearings instead of taking a chance on splitting a bearing that was not meant for splitting.

I think Thumper said Bambi was twitterpated over a young lady deer. Probably Not really how Vibration Analysts feel about scary bearing vibrations, but I like to use it anyhow.
