Seismic Fullspin 6-Ball Ceramic XT Classic Cuscinetti (set of 8)

THE BASICS 6-Ball system Less total friction, better acceleration and speed on straightaways. Recommended for LDP and top-speed pursuits. Premium Ceramic balls Lighter, smoother, harder, lower in friction, self-lubricating, more heat-resistant, completely rustproof. Increased acceleration, speed, and durability versus Steel balls. 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. Next-gen Classic spacing / alignment system Fullspin's unique profiled spacers precision-machined from premium bearing steel with smarter, stricter dimensional specs have broad flanged ends that square up against matching extra-wide inner ring surfaces with up to 67% more contact area, powering unprecedented Classic alignment precision and stability. System levels and steadies all working components of seated bearings far better than any other Classic design, to unleash truly exceptional 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. 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.
