Seismic Fullspin 7-Ball Steel XT Built-In Bearings

Fullspin Bearings

With few exceptions, other skate brands are just “tourists” when it comes to Bearings – sourcing average products from third-party brokers or small producers, with little or no input regarding engineering and manufacturing specs.

Once you scratch the surface, Bearings get wildly technical – so much so that unscrupulous brands can often get away with oversimplifications, misleading or exaggerated claims, and outright fabrications. But at Seismic, we’ve been mining the science and the facts – and innovating superior skate bearing tech – since 2011. We’ll give you the straight dope.

THE BASICS 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 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.

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.
