The major reason I would consider Tapered Roller Bearings (TRB's) is because of stiffness and deflection. The radius of the wheel and tire can create a fairly sizable moment arm that can result in relative movement of the wheel rotating axis vs. the axle shaft during a turn. However considering lubrication and friction the existing Angular Contact Ball Bearing design is more suitable. Load could also be an issue but I'm not worried about that as I don't think our trucks are really taxing the load rating of these bearings. Overall the bearing design used in our '56 is still in good condition so I'm not worried about it's capabilities of doing the job required, I just figured if SKF still made the TRB's I could get a free upgrade resulting in better wheel control.
