Improved tolerances and clearances to allow the bearing to take the combination side
and vertical loads imposed by skating better than normal bearings do (which are mostly
designed for electric motors)
High speed precision molded plastic bearing retainer – instead of the standard stamped
metal ball retainer
Single rubber shield for easier access to balls and reduces weight
Retainer and shield are removable to allow for better cleaning
Polished Chromium steel balls and races
Specially formulated Speed Cream™ for superior lubrication – resists the dirt found in
the skate environment (to the extent possible)
Not ABEC rated, but Skate Rated
Bones bearings were designed specifically for skates
To merely give Bones an ABEC rating would be to ignore all the improvements
engineered into the Bones bearings and the resulting difference between Bones and
standard ABEC rated bearings
Bones Swiss have earned their name through years of proven, dependable performance
from the best skaters in the world.
