I have been using mine for about 6 months too and there doesn't appear to be any real wear.
Dyneema rubbing against dyneema would have a heap of friction and generate heaps of heat but rubbing against a super smooth polished steel surface I doubt that it would generate much heat at all.
I believe the BWS kites use steel rings that are similar but with these sliders just have a bigger circumference so spread the load more.
I think if you check your pulleys regularly and make sure they are hanging straight they should last ages the problems start if they are not hanging straight and the bridle starts rubbing on the sharp edge of the top section of the pulley and not on the roller, or if a gap opens up between the roller and the fixed part of the pulley and the bridle jams in there.
With the sliders there is no maintenance or checking required, time will tell but I don't think I will ever use a pulley again.

Where do you get the sliders from?
