We spent over two years nerding out with a crack team of American engineers from one of the biggest and best bearing factories in the world, to raise the bar on bearing tech yet again! Roll tighter, truer, faster, and smarter on Fullspin: the absolute best skate bearings in the entire history of skate bearings!

THE BASICS (Scroll down for more in-depth technical info.)
7-Ball system – Best overall balance of speed and resistance to frequent impacts and side loads. Recommended for high-speed turning / sliding and all style / trick disciplines.
Premium Ceramic balls – Lighter, smoother, harder, lower in friction, self-lubricating, more heat-resistant, completely rustproof. Increased acceleration, speed, and durability versus Steel balls. Manufactured to superior Grade G10 spec for truer, lower-friction ball spin inside bearings.
Exceptionally tight, consistent assembly and raceway tolerances – Significantly less internal play, friction, wear, and noise. Superior speed, handling, and durability.
Extra-tough steel and thicker outer rings – Raceways hold strictest curvature and finest surface finish – and bearings stay tight and fast – for far longer. Thicker, 60%-stiffer outer rings resist flexing, spin truer and faster, and keep seals from popping off on extreme impacts. Premium black oxide surface treatment adds exceptional corrosion resistance.
Next-level patented Built-In spacing / alignment system – Built-in half-spacers with extra-wide flanged ends* square up inside wheels with more than double the contact area of ordinary Built-In interfaces – powering absolutely unparalleled alignment precision and stability. System levels and steadies all working components of seated bearings far better than any other design (Built-In or Classic), to unleash near-perfectly optimized paired performance. Synergizes with all advanced features in individual bearings to maintain exceptionally consistent wheel contact and grip; support extremely predictable slide performance; and noticeably extend both wheel and bearing life.
High-end lubricant – Formulated for peak performance under real-world skating stresses (not max free-spin time).
Labyrinth-style outer seals – Edges of seals slot inside V-shaped grooves for maximum resistance to dust and debris.
Next-level anti-contaminant ball retainers – Expanded outer diameter slots into groove in outer ring just like a second seal, to form a unique integral barrier against dirt and grime.
