The easiest way to determine the correct bearings for your trailer is to use the industry standard numbers stamped into the lip of the bearings. This would require removal of the hub. Your measurement, 1-1/16 inches, comes to 1.0625 inches and the inside diameter of the, item # L44649, bearing is 1.063 inches which would be a close match. This bearing is usually mated with the same bearing on the inner race or with, item # L68149, bearing for an inner bearing. You will need to know what each bearing size is to order replacements.

The Bearing Kit for #84 Spindle, item # BK2-100, you selected may be the correct fit but we will need to check the existing parts to be sure. I have incldued a link to a video showing how to remove, inspect, and replace bearings that might help.
