Replacement Bearings Races and Seals for a 1974 Midwest Boat Trailer

Question:

I have a 1974 Midwest boat trailer it is a single axle. I would like to change the wheel bearings both inner and outer with the races and seals. I have them removed and can not find any numbers on the bearings or races. The inner bearings are 1.25 inch ID the inner race is 2.30 OD. The outer bearings are .750 ID the race is 1.781 OD the outer race has a partial number LM 010 the first 0 may not be correct.

Based on the measurements that you have provided, check out the outer bearing # LM11949 and race # LM11910. This bearing and race combinations has an inner diameter of .750 inches and an outer diameter of 1.781 inches.

For the inner bearing and race you will need bearing # LM67048 and race # LM67010. The inner diameter for this bearing and race combination is 1.250 inches and the outer diameter for race # LM67010 is 2.328 inches. We do not have a race with an OD of 2.30.

The grease seals that are compatible with inner bearing # LM67048 are the 10-10 grease seals # RG06-090. These seals have an inner diameter of 2.125 inches and an outer diameter of 3.376 inches. I have attached a link for each of the products that I have mentioned for you to check out.
