15 imported bearing damage, the root cause and preventive damage: bearing to bear the load rotation, inner ring, outer raceway surface or with dignity because tired and scrolling display scaly out of condition.
Damage reason: too much load.
Poor installation (
The parallel linear)
The torque load dirt intrusion, ooze water.
Poor RunHua, lubricants doesn't fit, the bearing clearance is not appropriate.
Poor precision bearings, bearing box non-uniform stiffness, large shaft deflection value, rust, corrosion, scratches, marks (
Surface deformation situation)
Lead to the development of the trend.
Damage action: check the size of the load bearing and the laboratory application again.
Improved installation method, improved sealing equipment, power off when the antirust processing.
Use a moderate viscosity of lubricant, improvement RunHua way.
Check the shaft and the precision of the bearing.
The inspection clearance.

In contact with the inside and outside the circle of roller surface contact stress is produced.
Due to internal and external ring and rolling element in the work of relative rotation, so the contact stress is fluctuating.
When the contact stress exceeds limit value, fatigue crack occurred under the surface layer, gradually extended to the surface, lead to internal and external ring rolling body surface fatigue pitting, lead to bearing rotation accuracy loss, noise, shock and vibration.
So the pitting is rolling bearing failure modes.
