Three major factors of agricultural bearings failure

1 contact fatigue failure
Contact fatigue failure refers to the agricultural bearings  surface subjected to alternating stress arising from failure. Contact fatigue spalling in sliding bearing surface, often accompanied by fatigue crack, first from the contact surface following the largest alternating shear stress, and then extended to the surface spalling of different shapes, such as point to point pitting or pitting spalling, shallow spalling in the peel into small flakes. Due to the peeling surface gradually expanded, and often deep extended, forming deep spalling. Deep contact fatigue failure fatigue spalling is source of.
 2 clearance change
Bearing in the work, due to the impact of external or Thrust Roller Bearings
  internal factors, so that the original clearance change, accuracy, and even cause "killed" called the clearance change failure. External factors such as excessive interference, the installation is not in place, the temperature rise caused by the expansion of the quantity, instantaneous overload, internal factors such as residual austenite and residual stress in an unstable state, is the main reason that causes the failure of the clearance change.
3, the wear failure
Wear failure refers to the failure of the relative sliding friction between the surfaces due to the surface of metal wear and the. Continuous wear will cause damage to bearing parts gradually,Full complement cylindrical roller bearing
 and eventually lead to sliding bearing loss of dimensional accuracy and other related issues. Wear may affect the shape change, increased clearance and surface morphology changes, may affect the lubricant or its pollution to a certain extent and cause lubrication complete loss of function, and thus loss of bearing rotation accuracy and can not operate normally.
