Description
- Abrasive particles lead to wear of the rolling elements, raceways and cage
- Worn surfaces exhibit a dull, frosty gray appearance
- Wear steps can often be observed on the roller and flange thrust surfaces and near the edges of rolling paths
Causes
External contamination
External contamination led to abrasive wear of these cone – roller assemblies. The rollers exhibit a dull, frosty gray appearance.
Abrasive wear of tapered bearing rollers resulting from contamination.
Abrasive wear on a tapered bearing cone thrust flange resulting from external contamination.
A groove worn into a cylindrical roller by a hard particle debris imbedded in the cage.
