I purchased these bearings because I forgot to relube my old pair and they welded together during DH. i put them on and raced my friend who had the same board just smaller softer wheels and old grease balls bearings and he went faster than me. when i went to check my bearings out i realized they were given way to much play and i could actually jiggle the inner ring. because of this they don't spin as fast or long. these were not put together well and little too expensive for the quality i got.

are these bearings ceramic? thanks Dan Loveland Writes - These are not ceramic bearings. These are double shielded swiss bearings.

do these come with pre-lubed with Speed Cream, and 4 bearing spacers. and are they pretty easy to clean? Dan Loveland Writes - Yes, they come with 4 bearing spacers 10mm Width X 8mm Axle - They are very easy to clean. You can use a razor or something very fine to pop the shields off of the bearings. You can then clean your bearings and relube and reapply your shields. Happy skating.
