Peel
Injury Status: the load bearing stand rotated, the inner ring, outer ring raceway or rolling showing scaly due to rolling fatigue and the spin-off phenomenon.
Reasons: the load is too large. Poorly installed (non-linear) load torque foreign invasion, water，poor lubrication, improper bearing clearance improper lubricant. Bearing box accuracy is not good, the rigidity of the bearing box uneven shaft deflection big rust, corrosion points, scratches and indentation (surface deformation) caused by the development.
Measures: Check the load size and re-institute the use of bearings to improve the installation method to improve the seal, when the rust off. Use the appropriate viscosity of lubricant, improve lubrication methods. Check the accuracy of shaft and bearing box. Check clearance.

Peeling skin
Injury Status: showing slight wear with a dark side, the dark surface of the inside surface of a number of 5-10m depth to the small pre-press to be appropriate, improved lubricants and lubrication methods. Check the shaft, the bearing box accuracy.

Rupture
Damage state: the so-called fracture is due to the wall of the roller wheel or roller angle of the local part of the impact or impose excessive loading and a small part of the fracture.
Reasons: install by the blow. Load is too large. Use drop so bad.
Measures: to improve the installation method (thermal loading, use of appropriate tools folder).Correct load conditions. Bearing in place, support by the ribs.

Crack, crack
Damage state: the so-called crack roller wheel is rolling cracks or damage. If you continue to use it, will also include crack lubricants. Use the appropriate lubricant.

Wear
Damage state: the so-called wear and tear due to friction caused by the raceway or rolling surface, roller face, collar cage concave surface and the friction.
Reason: foreign invasion, rusted electrical erosion caused by development. Poor lubrication, as the rolling motion caused by the irregular slips

Measures: improved sealing device. Clean the bearing box. Fully filter oil, Check the lubricant and lubrication method. Prevent non-linear.
