Who is selling the ones with spiral grooves? They maybe old stock or? I am not aware of anyone making the original style bearing currently. By the way, they were not grooves, they were a strip of metal wrapped around a form to make the bearing roller. or is someone adding grooves to the solid type rollers? If you look at the original bearings, the grooves go in different directions, this helps move the grease around.
