Question:
Looking for axle bearing kits. Outer bearing is a Timken 1779 and the seal is a 203034. Six lug wheels and I believe that it is a 5200lb axle. Inner bearing is 1.5 ID. Hope this enough info.

Hey George thanks for the information! We have the Timken 1779 it is the Replacement Trailer Hub Bearing item # 1779.
The Timken 203034 seal has an outer diameter of 3" and an inner diameter of 1.875". The only seal we have which meets these dimensions is the Seal item # 29031.
That is all I was able to find though. We do not have a bearing with a 1.5" inner diameter and we do not have any kind of bearing kits with the parts I was able to find.
Do you know what kind of axle you have, manufacturer wise? Or could you tell me what kind of trailer it's on.

Hey George, did you find out what kind of axle or trailer you have? I'm asking because it might help others who are trying to find the right parts for their trailers.
