Seismic Fullspin 7-Ball Steel XT Built-In Bearings (8 Pk)

Seismic Fullspin (aka Tekton) 7-Ball Steel XT Built-In Bearings (integrated spacers & speedrings). A favorite among longboarders for downhill and freeride. Designed for use with standard 8mm axle trucks. The ultra-precise spacers with a wide contact surface ensure perfect alignment and secure fit within the wheels. The Fullspin bearings are remarkably durable and high-performing, with excellent dust resistance. Speed, acceleration, and control are all top-notch. Featuring 7 extremely durable steel balls with imperceptible friction. Equivalent to Abec 9 or higher quality. Set of 8 bearings.

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 – 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. 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.
