Bearing Damage Analysis

BEARING DAMAGE ANALYSIS

One of the main techniques in which we identify the root cause of the problem so that we act assertively on the cause. In addition to predictive and control techniques, it is the most important tool for troubleshooting maintenance issues.

In addition to application engineering, it is possible to offer exact solutions to unsolvable problems.

FOREIGN MATERIAL

Typical causes include poor cleaning, poor oil filtration, or oil seal deformation that can cause Spot Surface Pitting (NYK).

CORROSION

Typical causes include damaged packaging, improper storage, and worn or damaged seals.

INSUFFICIENT LUBRICATION

Typical causes include improper grease or oil viscosity, low lubricant flow rate, oil film thinning due to high loads/low circulation or high operating temperatures.

OVERLOAD

Typical causes include high load, misalignment, and localized load build-up.

WRONG ALIGNMENT

Typical causes include high load, shaft or bearing deformation, faulty bearing, shaft machining or misalignment during machine setup..

TRANSPORT DAMAGE

Typical causes include poor tool selections (hardened drivers) and unsuitable handling methods, which can cause Point Surface Pitting (NYC) blistering.

CAGE DAMAGE

Typical causes include improper assembly handling, tools, or incorrect assembly procedures.

INCORRECT FITTING APPLICATIONS ON BEARING OR SHAFT

Typical causes include incorrect size and shape distortions, stress risers in shafts or bearings, and incorrect machining.

SHOCK LOAD AND IMPACT DAMAGE

Typical causes include unsuitable handling and applications of sudden loads exceeding the material’s limits.

FALSE BRINELL IMPACT DAMAGE (WRAPPING DAMAGE BY ROLLER VIBRATION)

Typical causes include excessive vibration during transportation or when the shaft is stationary.

HIGH POINTS IN THE HOUSİNG

Typical causes include improper machining, grinding and repair methods.

BURNS CAUSED BY ELECTRIC CURRENT

Typical causes include improper grounding of equipment, weld damage or static discharge.

PLASTER WEAR

Typical causes include unsuitable oil film, excessive cage friction and high roller slip.

OVER AXIAL GAP

Typical causes include excessive backlash operation and incorrect setting resulting in narrow load bearing zone.
