| - 2 - accuracy in the widths of the outer races nor in the relative positions of the inner races. There will be gaps between the outer races,and therefore no need for oil grooves. It would not appear to be necessary to have a one piece construction for the bearing, but perhaps this would not save any cost unless we could use a standard roller bearing. To do this appears to require a bore of 1.3/8" in which case we could use R.L.S. 12½ 1.3/8" x 3" x 11/16". However, you may consider that the thrust bearings will not stand a further increase of bore to 1.375". Yours faithfully, FOR ROLLS-ROYCE LIMITED. CHASSIS PROJECT OFFICE. | ||
