The Timken 07100 bearing has a 1.9689 outer dimension. How is that the same as a L44643 which has a 1.98?

@MikeH that is a very slight difference but yes it is different. Normally the outer diameter is harder to get that exact of a dimension on since the components of the bearing can move.

@JamesonC Sorry I should have been more specific those are also the outer dimensions for the cups for those bearings. The reason I replied is I tried replacing the parts described cups and the 1.98 cup will not fit in my hub but the 1.9687 cup will. it's a really old trailer, I heated the hub and froze the cup still no luck.

@MikeH We don't carry it but it looks like the Timken is still available elsewhere which it sounds like you are in need of.

A BT8 spindle would have a diameter of .99 of an inch where the bearings would both install and would have a diameter of 1.24 where the great seal would ride. That would require a hub part #AKIHUB-440-2-1K for an idler hub. A BTR spindle would have…

The Malone MicroSport Trailer #MPG460G uses a #34823 grease seal and #L44643 inner and outer bearings like what you can find in the #BK1-100. For a complete hub assembly with the same 5 on 4-1/2 bolt pattern you can use the #CE13210.

The 30205 bearing that you referenced has an inner diameter of just under 1 inch (0.985 to be exact). We do not have this particular bearing or a hub that uses this size bearing available. The #L44643 bearing that you also mentioned has an inner…
