Question:

I have the measurements on the seal I'm looking for: 1.25 I.D. 1.97 O.D. .46 width Can you help me find a seal for an old trailer that fits those dimensions or close to it?

Expert Reply:

The correct replacement bearing for your Timken 07100 is the # L44643, but to determine the correct race and grease seal you will need to measure your hub.

As long as the outside diameter of your current race is 1.980" you will be able to use race # L44610, but for the grease seal you will need to use digital calipers like # PTW80157 to precisely measure the spindle where the grease seal rides and the hub where the grease seal rides as shown in the included diagram.

If you can provide these measurements I would be happy to confirm the correct replacements for you.

Based on the measurements you provided the correct grease seal is the Double Lip Grease Seals (pair) # RG06-010 which have an I.D. of 1.249", O.D. of 1.983", and a thickness of .25". While these will are a bit narrower than you current seals, it will still work just fine. I included a video of the # RG06-010 for you to take a look at.
