Legendary Bones Swiss bearings have been the industry standard ever since they were introduced in 1983, and are still a favorite with professional skaters. Fast, smooth, and very long lasting, they remain unequaled in their class. Bones Swiss have earned their fame through decades of proven, dependable, superior performance for the best skaters in the world. No hype, (ABEC-99!) just the best - ask anyone who has been skating for a few years.

Note:Â All Bones Bearings are Skate Rated to withstand the destructive forces created by high performance skating. This is Powell's way of saying that just using a bearing with an ABEC rating is not enough to ensure that a bearing will perform well for skating, since ABEC ratings were intended for electric motor bearings, not skate bearings. Powell has adjusted the tolerances, clearances, lubricant, and component materials to optimize Bones Bearings for use in dirty, high impact environments - where you skate. That's why they roll faster and last longer than mere ABEC rated bearings.
