Peel

Damage state: Bearing loads rotation, an inner ring, the outer ring raceway or the rolling decent due to rolling contact fatigue and showed scaly peeling phenomenon.

Reasons: the load is too large. Poor installation (non-linear) moment load foreign body penetrated, water. The poor lubrication lubricant inappropriate bearing clearance inappropriate. The bearing box accuracy is not good, the rigidity of the bearing housing uneven axis deflection rust, caused by the development of point of erosion, abrasion and indentation (surface deformation phenomenon).

Measures: Check the size of the load and again Institute bearings used to improve the installation method to improve the sealing device, anti-rust downtime. Use of appropriate viscosity of the lubricant, to improve the lubrication method. Check the shaft and bearing box accuracy. Check the clearance.
 
Peeling skin

Damage states: showing a dark surface with a slightly worn, dark surface inside by the surface a number of minute cracks deep to 5-10m, and tiny shedding (slight peeling occurs in a wide range)

The reasons: lubricant inappropriate. Foreign matter into the lubricant within. Lubricant caused by poor surface roughness. The paired rolling parts of the surface finish poor.

Measures: the lubricant is selected to improve the sealing means to improve the surface finish of the paired scroll parts.
 
Card injury

The damage status: the so-called card injury arising due to injuries generated on the sliding surface portion of slight burns rollup surface damage. Chute surface, the rolling surface in the circumferential direction linear scars. Slew linear scars roller end surface close to the roller end surface of the collar of the card injury.

Reason: too much load, too much preload. Poor lubrication. Foreign objects. The inclination of the inner ring outer ring, the shaft deflection. Axis, the precision of the bearing housing is bad.
Measures: Check the load size. Preload should be appropriate. Improved lubricants and lubrication methods. Check the shaft, the bearing box accuracy.
 
Fracture

Damage state: the so-called fault is applied to roll the track wheel flanges or the roller angle of local the musical impact or excessive load while a small part of the fracture.

Reasons: installation took a hit. The load is too large. Drop the use of bad.

Measures: improving the installation method (thermal loading, use appropriate tools folder). Correct load conditions. The ribs by supporting bearings installed in place.
