Seismic Ceramic Tekton classic bearings.
8x bearings and 4x spacer
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. Meets or exceeds all criteria for ABEC-9 rating. Eco-friendly packaging: No oversized metal tins or plastic boxes – just a minimal recyclable cardboard box. No fake tech or exaggerations: Just more speed and longevity through real science and no-BS engineering! 100% free of: • Random bearing tech adapted from other industries just for the sake of novelty. • Expensive over-hyped raceway coatings that interfere with optimal polishing and may actually grind on balls. • Over-hyped lubricant additives that accelerate wear not speed. • Misleading claims that industry-standard features and factory processes are unique or special. (e.g., deep-groove raceways with micro-channels, fine-polishing, fiber-reinforced nylon retainers, hand-inspection, ultrasonic solvent washing, etc.)
