Brinelling, flaking, incorrect mounting and foreign particle penetration can all contribute to excessive vibration or axial runout.
Please confirm that the impeller comes to rest at a different location - no brinelling has occurred.
Along with the material research, the company also reviewed coating technologies, which are critical to achieving micro-sealing and minimizing the effects of both thermal and mechanical stresses, such as galling and brinelling. "Any alloy on its own is not enough to achieve a perfect seal--a zero leakage range--because surface finish comes into play," Zwick noted.
An insidious form of bearing failure is false brinelling, which occurs when an unused motor is exposed to vibrations.
This eliminates any condition of the balls having point contact with the raceways and therefore avoids ball indentation (brinelling) to the raceways.
Steel construction provides maximum working pressures and burst strength and prevents brinelling.
However, even low-voltage current passing between a ball and race in contact can cause rapid heating and lead to false Brinelling, Macdonald said.
All of the weight and force is concentrated on the points of contact, creating very high pressures which can lead to brinelling. They are more easily damaged in a crash for the same reason.
These signs of localised damage (and widespread damage in some cases) appeared in many forms--including abrasive wear, adhesive wear, spalling, fatigue, corrosion, fretting, cracks, indentations, discolouration, false Brinelling and degradation/starvation of grease.
The Holmbury HPA series 10,000 psi ball seal screwed couplings feature a screw connection mechanism that will eliminate brinelling, the indentation of the locking balls into the retaining groove, the company said.
They are available in 303 stainless steel for chemical handling applications, in solid brass for water transfer, and steel to provide maximum working pressures and burst strength, as well as to prevent brinelling. They are available with 1-in.
