boor lubrication due to oil quality, defect at lubricant system, delay or negation of routine maintenance, overload, engine harshing with over speed, boor cooling for lubrcant.
Maintenance not performing on time.
Apply suitable grade lubricant and fixing as per procedure.
Replace the the baring as per service owner manual duration.
there are more Problems but the main Problem is Friction and Bad Method of lubrication ..... Bearing May work out of the Limited Speed that affect Badly on it
Insufficoent / improper lubrication
Damaged oil seal / dust formation
Miasalignment
Manufacturing defect
running out of rpm
Excessive loads
Corrosion
Cause of bearing damages is no grease and long time uses.
non lubricating
oil seal damaged& dust forming
alignment problem
manufacture fault while assembling
running out of specified rpm
over driven
1. Improper Load Distribution
2. Lub oil distribution system failure (even in particular bearing)
3. Contamination of Lubrication oil
4. Damage in the shaft / pin.
5. Un-noticed Hot spot in the bearing
excess loads
lubrication defect
not proper mount
alignment not done properly
low quality materials used
Improper lubrication is the major cause of bearing failure.
1\\ Dirt in lubrication system or in bearing back itself
2\\Oil starvation
3\\Misassemble
4\\Improper machining of components (shaft, housing ant etc)
5\\Overloading
6\\Corrosion
7\\cavitation
