Versatile Free-Spacer System:Precisely-sized spacers square up against bearings and stabilize them inside wheels. Combines withTighter Radial Tolerances(3µ – 5µ) that minimize torsional play inside bearing assemblies. Locks inhighly-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 forpeak performance under actual skating stresses,notmax 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.)
