Has anyone tried Fireball Dragon bearings? Or is that just pure sacrilege because it's "longboard shit"? I like the fact that they give exact specifications for their products and claim they are manufactured within +/-0.02mm tolerances. They also claim to have improved seals and heavier grease on the Endure version for longevity.
@MysticalTypeExperience, for what it’s worth, saying that they are manufactured within +/-0.02 mm tolerance is largely meaningless, not just because they do t specify which parts are maintained to that tolerance. ABEC-1 bearings are +/-0.008 mm for reference, and ABEC rating has nothing to do with surface finish, roundness of the balls, or material selection. They also have nothing to do with how “fast” the bearing is, just how precise it is, and thus the maximum speed capability. ABEC-1 bearings more than exceed the speeds that are seen in skateboarding.
Unfortunately what
is important to skateboard bearings doesn’t actually have any standards, so there’s not really any way to accurately compare bearings. Essentially more expensive is generally better, but choosing which expensive ones are the best is at most an educated guess.
Grease will make them last longer, but they will be “slower” due to the higher viscosity compared to oil.
