How to Confirm Correct Size of Grease Seal


Bearing Kit for #84 Spindle, L44649/L68149 Bearings, 10-19 Double Lip Seal I know the bearing and races sizes are correct but is this for sure the right seal size I need? axle is 1 1/16 x 1 3/8

You can verify that the 10-19 grease seal included in Bearing Kit # BK2-100 is the correct one for your spindles by taking two measurements.

First you want to measure the rear hub bore where the seal is inserted. The seal's outer diameter needs to be fairly close to this hub bore dimension. You'll need a precision caliper to measure the hub bore to the nearest thousandth - to three decimal places such as 1.234. The 10-19 seal has an outer diameter of 2.565-inches.

Next you'll need to measure your spindle at the point where the grease seal rides. The linked diagram shows you this point, labeled as B. This needs to match closely to the grease seal inner diameter, which in the case of a 10-19 is 1.719-inches.

I have a shorelander trailer that uses 1 1/16 and 1 3/8 bearings and it has a stainless steel seal wear sleeve that measures 1.750. I am finding conflicting information as of which grease seal to use. But it seems as though it is 2.565 OD x 1.719 ID. I just received 12 grease seals that I ordered from you # 58846 and that inner lip just below the spring measures around 1.660 to 1.665 so how can this be a 1.719 ID. And good luck cross referencing shorelanders part #4410130.

That's really odd that you received those measurements - the Grease Seal # 58846 should indeed have a 1.719" inner diameter. Have you tried actually installing one of them to see if it fits over the spindle?
