Hard to see but it looks like it wasn't getting any lube oil. Is that bluing on the inner race ? Do the rollers look like they have wear prior to the damage ? If there is wear due to lack of lube oil I wonder if it would have been beneficial to drill a small lube oil hole from the lube feed passage.
