Seismic Tekton bearings.
8x Lager plus spacer
Tekton™ 7-Ball XT™ Steel Bearings with Classic Free-Spacer System Next-level skate bearing tech – more speed, better handling, longer life! Versatile Free-Spaced Design • 50% Stronger XT (Extra-Tough) Steel Casings • Tighter Assembly Tolerances • Dust-Resistant Ball Retainers • 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. 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 Steel Balls: Superior concentricity, surface smoothness, strength, and durability. 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.)
