How to Pick Out a Replacement Seal for a Surplus Military Axle

Question:

I have an old trailer with an inner bearing 24780 TIMKEN. It may be a surplus military axle. What bearing seal should I use for it? Thanks-

In order to pick out a grease seal to match the hubs of your military axle you are going to need to remove the hub from your spindle and using a dial caliper or micrometer get the exact diameter of the spindle where the seal rides and then get the exact inner diameter of the hub bore where your seal fits in the hub.

The spindle measurement will be the inner diameter needed for your replacement seal, the inner diameter of the hub will be the outer diameter of the seal you need. Once you have that info check out the link I attached to the right where you will be able to select the dimensions you need from the facets on the left and the correct seal (if available) will be listed.
