Bearing starting to run hot
Bearing starting to run hot
(OP)
A 5 ton rotor at 500 rpm is supported on two big spherical roller brngs ( Skf 23072) It is not a pumped oil lubrication system but regularly greased with a carefully selected grease
One bearing has started to run much hotter than normal and it is thought to be failing. We took it off line and after cleaning out all the grease the bearing looks perfectly ok on the races and rollers.
My question is , does a rising temperature indicate a failing bearing and if so, how ; and can this temp rise be caused by other things??
All comments will be appreciated
Thanks CM

same bearing overheats. If the second bearing
overheats, it is an application problem.
RE: Bearing starting to run hot
In addition to looking good, spherical bearings must have internal clearance, often set (reduced) by tightening a tapered adapter that locks the inner race to the shaft.
If the adapter was overtightened the internal clearance would be reduced or eliminated, and the bearing would start on a hot-hotter-toast sequence.
