Tekton™ 7-Ball XT™ Steel Bearings with Patented High-Precision Built-In Spacer System The bearing behind the Official IGSA Downhill Speed World Record – 80.83 mph by Mischo Erban! Next-level skate bearing tech – more speed, better handling, longer life!
Ultra-Precise Alignment • 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
PATENTED Spacing System:Built-in half-spacers end inextra-wide contact surfaces(U.S. Pat. #9,126,101) that square up and self-stabilize inside wheels – correcting for flaws in bearing seat levelness, bearing seat spacing, axle diameter, and axle straightness. Combines withTighter Radial Tolerances(3µ – 5µ) that minimize torsional play inside bearing assemblies. Locks insuper-precise alignment, protects against friction and wear –better than any other system.Minimizes noise, too.
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. Extends 0.5mm outside to form built-in washer.No bearing spacers, axle washers, or World Record budgets required!
NOTE:The broad Tekton XT flanges may not fit hub-less street wheels with old-style, oversized bearing supports, which sometimes leave the wheel’s central hole smaller than the flange (15mm in diameter). For wheels of this type, use Tekton Classic or Tekton LITE Built-In bearings.
