⚡ Seismic Fullspin 6-Ball Steel XT Built-In Bearings (set of 8)
The Seismic Fullspin 6-Ball Steel XT Built-In Bearings (set of 8) is made for skaters looking for a defined bearing setup. Ball count, material and spacer design determine how the set suits a chosen style of riding.
★ Bearings for your setup
The 6-ball system is designed to reduce friction and support acceleration and straight-line speed. Seismic recommends it for long-distance pumping and top-speed riding.
⚙️ Balls and precision
Premium steel balls are made to tight tolerances for consistent rotation and reduced internal play. XT versions add reinforced outer rings and tight raceway and assembly tolerances.
Mounting and compatibility
The Built-In setup integrates half-spacers into the bearings. Their wider interface helps align the bearings and stabilize their position in the wheels.
