napa should be able to cross them, i know they can for seals atleast, i had a few seals from my caterpillar grader and took them in expecting to measure and match them up, the guy looked at the cat number and put it in the computer and brought me out a CR seal that was the same size

Try Motion Industries, if there is one near you. They can usually cross about any brand bearing and seals. good Luck

This might help. It will give you NSK and RHP numbers from a cross referenced bearing from other manufacturers

We've got an older Bearing Bible that crosses just about all of the "brand" names like Timken, Bower, etc but I've never seen one that gives crosses for CAT numbers. That would make things way to easy.... If you get me the dimensions though I can look them up that way with no problem. Give me the ID and thickness/height of the cone and the OD and thickness/height of the cup and any special things like a snap ring groove on the cup, etc. With these dimensions it shouldn't be a problem to find what you want. One thing though, depending on what their in CAT has been known to have special bearings made just for the that are slightly off what you can readily get just so you have to get them from them.
