What to do if the inner ring of the rolling bearing in a centrifugal pump is burned to the shaft
Thread Content
In daily work, it often happens that the inner ring of a bearing burns and sticks to the shaft journal. I would like to share some effective methods for removing the inner ring. For example, what should be done in a gas handling unit area under special conditions?
It can be heated using gas welding, provided that welding is allowed.
I usually heat it up first and then pull it; if that doesn’t work, I use welding or a angle grinder to make a cut, and then use a flat tool to pry it off :)
I agree with the method on floor 4; we usually use this approach as well
If heating is not allowed, you can try a hot oil bath.
After heating, pull it out; if welding is possible, use gas welding to heat it, and if welding isn’t an option, steam heating or an oil bath will work as well.
