Fullspin™ Precision-Profiled XT™ Steel Spacers

Fullspin™ Precision-Profiled XT™ Steel Spacers
Premium 0.400-inch steel bearing spacers.
Fit standard 8mm axles only.

Fullspin’s unique Precision-Profiled XT (Extra-Tough) Steel Spacers have broad flanged ends that square up against Classic (non-Built-In) inner ring surfaces with up to 67% more contact area – powering unprecedented Classic alignment precision and stability.

Design levels and steadies all working components of seated bearings far more precisely and stably than Classic spacers from other brands – which are typically rough-cut from thin-walled, easily-bent iron or aluminum, with oversized bores that rock on axles.

This is hands-down the most advanced Classic bearing alignment tech ever seen in the skate world, and it unleashes truly exceptional paired performance. Synergizes with working features in all high-quality Classic bearings* to maintain exceptionally consistent wheel contact and grip; support extremely predictable slide performance; and noticeably extend both wheel and bearing life.

Precision-machined from premium bearing steel with advanced heat-treatment for unmatched strength and toughness.

Spacer width set to extra-strict 0.400-inch tolerance, to support highly accurate positioning of paired bearings inside finer wheels with well-engineered hubs.

Radius reduced to bare minimum on spacer edges, for fuller contact and more stable alignment at bearing interfaces. Bore specs dialed to maintain exceptional straightness on finer axles.

* For best results, use with Seismic® Fullspin Classic bearings, which have extra-wide inner ring contact surfaces that exactly match the profiled spacer ends.
