Seismic Fullspin® Precision-Profiled XT™ Steel Bearing Spacers

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

Fullspin’s unique Precision-Profiled XT (Extra-Tough) Steel Bearing 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.
