Sir
I have owned these bearing for about 1.5 years and these bearings are just not worth it. They last a month more than normal bearings and their perforance can be matched by a steel bearing with proper cleaning and high speed oil. I tested both bearings, ceramic on the left and steel on the right and the steels roll as good if not better than these ceramics. Tested with high speed oil on both and still the steel bearings roll as long as the ceramics. I even tested the bearing after a 8 min race and the steel bearing is still identical to the ceramic bearing. Both have the same bearing wobble now, ceramic having the most wobble. Very disappointing!
Did you find this helpful?
