These Deep Groove Ball Bearings were developed to cater for the exacting requirements of contaminated or difficult lubrication conditions. Specially treated bearing steel ensures the components last up to twice as long with contaminated lubricant as conventional Deep Groove Ball Bearings.
This results in significantly longer service lives in both difficult (low viscosity and/or contamination) and normal conditions
