I received a bearing? A koyo brand bearing American made a positive! Wished heartland products would have disclosed that, I had thought I was receiving Torrington or in there discription Timpken brand. Instead received Torrington style from different manufacture not disclosed in there discription.
Heartland Products Note: Koyo purchased Torrington facilities/operations from Timken. There are no "Torrington" products under that name.
