Seismic – Fullspin 10mm Steel XT Built-In – Bearings

Seismic Skate – Fullspin 10mm Steel XT Built-In – Bearings

Fullspin™ 10mm Steel XT™ Bearings with Patented High-Precision Built-In Spacer System
Next-level skate bearing tech – more speed, better handling, longer life!
Fit standard 8mm axles only.

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
6-Ball system – Less total friction, better acceleration and speed on straightaways. Recommended for LDP and top-speed pursuits.
Premium Steel balls – Superior Grade G10 balls spin truer with less friction 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. Coated with a strong rust-preventative agent, but more economically finished without the black oxide anti-corrosion surface treatment seen in premium Steel and Ceramic XT models.
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.

We don’t bother with the ABEC rating system, which measures only the most superficial dimensional tolerances of the outer and inner rings – all of negligible relevance to real-world skating performance. Low-versus-high ABEC ratings have no direct correspondence with poor-versus excellent skating performance in the real world.
