Bearing size chart — find a bearing by size
Know the size but not the number? Start from the bore diameter (the shaft size the bearing fits). Pick a bore below to list every bearing that uses it — deep groove, roller, thrust and more — by outside diameter and width, each linking to its cross-brand cross-reference. To work back from a bearing you can only measure, see identify an unmarked bearing.
