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.
