Seismic Tekton 7- Ball XT Classic – In Skateboard Bearings
Tekton™ 7-Ball XT™ Ceramic Bearings with Classic Free-Spacer System
Next-level skate bearing tech – more speed, better handling, longer life!
Precision-Profiled Steel Spacers • 50% Stronger XT (Extra-Tough) Steel Casings • Tighter Assembly Tolerances • Dust-Resistant Ball Retainers • Premium Lube
– Superior speed & acceleration
– More consistent wheel contact & grip while cornering
– More predictable slide release & hookup
– Longer wheel & bearing life
Next-Gen Profiled Steel Spacers: Extra-wide contact surfaces square up against bearings and stabilize them far better than traditional thin-tube spacers formed of much softer iron or aluminum. Combines with Tighter Radial Tolerances (3µ – 5µ) that minimize torsional play inside bearing assemblies. Locks in super-precise alignment, protects against friction and wear, minimizes noise.
XT Construction: More than 50% tougher! Superior steel, thicker outer casings, and advanced heat treatment. Ball raceways hold smooth polish, and bearings stay tight and fast, for far longer! 50%-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 Black Ceramic Balls: (genuine N4Si3 / trisilicon tetranitride) Lighter, smoother, harder, heat-resistant, rustproof. Reduce friction, increase acceleration and speed, scour / clean raceways! A whole new realm of fast.
Advanced Dust-Resistant Ball Retainers: Keep bearings cleaner for longer, without the added friction of a second seal. Formed of Dupont® engineering-grade Nylon.
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: Black outer casings, removable rubber-coated steel seals with printed graphic.
