Bones® Bearings are the skate industry leader and favorite choice of professional skaters, and have been since their development in 1981. Over the past years, Bones® Swiss have become legendary because of their superior speed quality, and longevity. Even though Bones Swiss are the top rated bearing in skating, we don’t give them an ABEC rating. There is a good reason for this... thank you for asking.
Bones® Bearings out perform all other bearings because we went to the trouble to skate rate Bones® Swiss and Bones® REDS®, not just select an ABEC rated industrial bearing and put a customized plastic shield on it. Bones have been completely redesigned for skating from the ground up and are built to Bones® specifications that include Skate Rated™ components, lubricants, tolerances and clearances.
Bones® Bearings component parts are engineered and tested to withstand the high impacts of hard landings, the high side loads of turning, and (to the extent possible) the dirt of skate environments. As a result, Bones® roll faster and last longer than other bearings. To merely give Bones® an ABEC rating would be to ignore all the improvements we have engineered into Bones and the resulting difference between Bones and standard ABEC rated bearings. Since there is no appropriate ABEC rating that will reflect the superior quality of Bones® Bearings, we have given them their own rating, Skate Rating™, to let you know that Bones® Bearings are special and made just for skaters like you, not for electric motors.
