- 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
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.
