Seismic Fullspin 7-Ball Lite Built-In Cuscinetti (set of 8)

THE BASICS

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 Steel balls – 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.

State-of-the-art Built-In spacing / alignment system – A more affordable design without Fullspin’s patented Built-In flange tech (seen in Steel and Ceramic XT models), but still superior to Built-In systems from other brands. Integral half-spacers with smarter, stricter dimensional specs square up inside wheels with outstanding precision and stability. System levels and steadies all working components of seated bearings to unlock truly exceptional paired performance. Synergizes with all advanced features in individual bearings to maintain extremely consistent wheel contact and grip; support highly 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.
