Bones Swiss Bearings

Bones Swiss bearings feature high-precision, hardened chromium steel balls running inside micro-honed raceways, optimized for low rolling resistance and high impact resistance. The single, non-contact removable rubber shield allows effortless maintenance while minimizing drag, and the high-speed Delrin® ball retainer ensures uniform ball spacing with minimal friction. Factory pre-lubricated with Bones Speed Cream®, they roll fast straight out of the box and can last for years with proper cleaning.
