This 20219-MB bearing is a Open Type Barrel Roller Bearing with a machined brass cage and a standard radial internal clearance. The bearing's dimensions are 95x170x32. Got this bearing at an auction which was a supply warehouse that was closing. I copied the description from FAG web site. I know nothing about this bearing other than what you see....THERE IS NO BOX!! It was wrapped as seen in the last pic....it is still "greasy" from the coating they put on it. These list for over 0. If you have any questions please let me know.
