Bearing purchased from Locateballbearings.com. Bearings are in a plain box that says Ball & Roller Bearings with a sticker affixed with bearing number. Bearing is in unsealed plastic inside the box. Bearing number plus skf written on one side of the outer race. All skf bearing I have used came in a red, white and blue box with the bearing in a completely sealed plastic wrapper. I am afraid to use these bearings. Could you comment as to if these are genuine or not?
