Standard bearings cost less intially, but when you consider they last 6 to 7 times less then ceramic and do not offer the performance gains or dependability what is the better value for your investment? Ceramic bearings all the way. Especially ours because of the quality of the materials used in construction and our design.
Ceramic bearings you can run dry for a long time before they fail. Failure in a standard bearing due to no oil or temp is inherit in the facts of the metalurgy. Steel on steel causes friction which creates heat and drag (less rpm's) and causes bearing fatigue and failure. Ceramic bearings are also made to exact tolerences that are way smaller then conventional bearings. The balls are measured by a machine for size and then sorted. Then inspected by hand for any imperfections and rechecked by manually measuring them fror accurracy to +/- .0002. If I remember correctly the machine can only sort them to a +/- .0015 accurracy.
Anyone that has ever used quality ceramic bearings can verify they greatly reduce friction, almost never need replacing and increase rpm's. Many engine guru's on this forum always use ceramic main bearings as one of their "trick engine mods". I have personally spun several of our ceramic ball bearings under load for 8 hrs at 8,000 rpm and the race is still cold to the touch. Try that with a standard metal bearing and you will have a nice burn print in your hand!!! We have purposely spun the bearings under load up tp 30,000 rpms for onr hour trying to get them hot or to fail. They really make a substantial difference in performance and savings.
As claimed our bearings are truly "Race Engineered" and here is why. We took our normal crankshaft bearing and started making tweaks and testing. We figured out a bearing design that when tested in 4 different engines rpm's increased from 620 to 885 over our normal bearing. There was no changes in longevity or accuracy. When redesigning the wheel bearings we took into account that the bearing will not only have radial loads, but axial loads (thrust) when cornering. Once again we were able to increase rpm's and bearing life when tested.
I will offer a 100% refund if not satisfyed with the product!!!! I have a legitimate business and I am licensed in the state of WI as a motorcycle dealer and ditributor. I have a Web guru working on designing the web site for me now. I started getting involved with the bearings as a way to support my son's racing. I want him to actually fill orders and do the customer contacts with my oversight to teach him responsability and commitment. Being a racer is more then throwing a leg over the seat and he has to work for his dreams too!!!!
