Thanks for the input tew45.... You just gave me the "AHH-HAA" moment I've been looking for.....

I'm so used to seeing open bearings with a crankshaft seal on the outside I hadn't thought of it as a stack with a seal on both sides, but yes that's what it is and makes sense now. The open inner bearing was covered on one side by the inner seal tight against it so no room for grease to escape, and the other side of it is against the spacer block which has no room for grease to escape due to it's full block design. Then the outer bearing could be one sided with the open side towards the spacer block....

Thank you for opening my eyes on this one. I will be using completely sealed bearings anyway for even more protection, But at least now I realize what they were thinking.
