We may have a grease seal that will work in your application however, my research had conflicting measurements for the Hadco 3122 that you referenced. I contacted my technical contact at Redline to verify that the Redline Grease Seal # 1105-100-031 that you referenced was a direct replacement, but they could not confirm this information.

In order to choose the correct grease seal to replace your Hadco 3122 a couple of measurements with a digital caliper are needed.

The first measurement is the outer diameter of the grease seal seat on the spindle and the other measurement is the inner diameter of the grease seal seat on the hub.

Since grease seals are rubber they can distort and shrink so measuring your current grease seal would not be reliable which is why we ask you to measure the spindle so you will receive the correct seal.
