Replacement Seal Needed for a Harbor Freight Haul-Master With Bearing 30205

Question:

what is the oil seal part number for bearing number 30205? Looks like the seal is close to 1.249 ID , 1.9830 OD. Just would like to make sure.

The bearing number alone is not the best indicator for a specific grease or oil seal. Trailers with the same bearing number could have different seals based on the spindle or hub that is being used. Bearing number 30205 is not a bearing that we offer and after doing some research that does not appear to coincide with any bearings that we currently carry.

The best way to determine which seal you need is by taking some measurements on your hub and spindle. We want the inner diameter of the hub bore where the seal sits and the outer diameter of the seal surface on the spindle (see photo). This will tell us the exact dimensions we need to match the correct seal. I recommend using a precise measuring tool such as a digital or dial caliper because these measurements must be exact down to the thousandth of an inch.
