Premium bearings with Classic free-spacer system.
Description from Seismic
Tekton™ 7-Ball Steel Bearings with Classic Free-Spacer System
Next-level skate bearing tech – more speed, better handling, longer life!
Versatile Free-Spaced Design • 30% Stronger Steel Casings • Tighter Assembly Tolerances • Premium Lube
– More speed & acceleration
– Consistent wheel contact & grip
– Predictable slide release & hookup
– Extended wheel & bearing life
Versatile Free-Spacer System: Precisely-sized spacers square up against bearings and stabilize them inside wheels. Combines with Tighter Radial Tolerances (3µ – 5µ) that minimize torsional play inside bearing assemblies. Locks in highly-precise alignment, protects against friction and wear, minimizes noise.
Tougher Construction: Superior steel and thicker outer casings boost strength by more than 30%! Ball raceways hold smooth polish, and bearings stay tight and fast, for far longer! 30%-stiffer casings resist flexing, spin truer / faster, keep seals from popping off on extreme impacts.
7-Ball Assembly: Classic configuration. Best overall durability against frequent high impacts and side loads.
Premium Steel Balls: Superior concentricity, surface smoothness, strength, and durability.
High-End Lubricant: Packed with premium “high-RPM” light grease from Kyodo Japan. Formulated for peak performance under actual skating stresses, not max free-spin time.
Inner Race: Specially contoured under seal to resist contamination.
Additional Features: Dupont® engineering-grade Nylon retainers, removable rubber-coated steel seals with printed graphic.
