What kind of damage can a cage bearing cause?
Since bearings that fail prematurely or unexpectedly cause trouble, it is important to be able to identify and predict failure beforehand, so that preventive measures can be adopted. Cage damage includes: Cage deformation, fracture and wear; Fracture of cage pillars; Deformation of side face; Wear of pocket surface; and Wear of guide surface.
What happens in the event of a bearing failure?
ISO Standard 15243 “In the event of extensive damage to or catastrophic failure of the bearing, the evidence is likely to be lost and it will then be impossible to identify the primary cause of failure. In all cases, knowledge of the actual operating conditions of the assembly and the maintenance history is of the utmost importance.”
What is the cost of a roller bearing failure?
TRIBOLOGÍA APLICADA, S.A. DE C.V. r Maintenance Failure of a Large Spherical Roller Bearing after 4 days Simple (easy) Failure Analysis Bearing cost = 32,000 USD. Production loss = 3’200 000 USD.
What causes a slewing ring bearing to fail?
Simple (easy) Failure Analysis Failure of a Slewing Ring Bearing after 1 year in an Electric Arc Furnace Lubricated by an automatic system. The grease drained out is heavily degraded and after some time filled with fatigue particles, at the most one year.
Since bearings that fail prematurely or unexpectedly cause trouble, it is important to be able to identify and predict failure beforehand, so that preventive measures can be adopted. Cage damage includes: Cage deformation, fracture and wear; Fracture of cage pillars; Deformation of side face; Wear of pocket surface; and Wear of guide surface.
What happens when a rolling bearing is damaged?
When a rolling bearing is damaged during machine operation, the entire machine or equipment can seize or malfunction. Since bearings that fail prematurely or unexpectedly cause trouble, it is important to be able to identify and predict failure beforehand, so that preventive measures can be adopted.
Where does spalling occur in a bearing failure?
discrete particles of material. Spalling can occur on the inner ring, outer ring, or balls. This type of failure is progressive and once initiated will spread as a result of further operation. It will always be accompanied by a marked increase in vibration, indicating an abnormality.
What causes 80% of all bearing failures?
Some researches in the bearing industry have stated that improper lubrication can account around 80% of bearing failures [8]. Failure can be the result of excessively long time lubrication without renewing, unsuitable lubrication and lubrication contamination [12].
