Enduro makes a big deal about using LLB seals as being different from RS seals. Apparently, most RS seals just mate to a flat part on the inner race. Enduro's LLBs have grooves on both the inner and outer race, with the outer race being fixed, and the inner race having it's edge sliced a bit to have two sealing edges.

We may be overthinking this. My advice would be to install these and see if they ride ok. If not, then there's all the time in the world to worry about it.
