Should There Be A Gap Between The Seal and The Inner Bearing In My Hub

Question:

I am replacing a set of bearings/races/grease seals on my trailer hubs. The bearing kits I bought BK1-150 come with 10-60 grease seals. When I was seating the seal I noticed that it was not touching the inner bearing when it was flush with the hub. Is this okay or should I seat it until it is touching the bearing which would leave the gap between the seal and hub? Im concerned because I dont know if the play in the bearing because the seal is not against it is normal.

As long as the seal in the bearing kit part # BK1-150 is flush with the hub it is okay to have a small gap between the seal and inner bearing. When installing the seal you only insert it enough so that it is flush with the hub.

The seal's job is to keep the grease inside of the hub. As long as the inner bearing is seated against the grease seal shoulder on the spindle then you should not have an issue. I have attached a video of a hub installation for your reference.
