Seismic Tekton 7-Ball XT Ceramic Built-In Longboard Skateboard Bearings
Introducing the newest bearing innovation from Seismic: Tekton 7-Ball XT Ceramic Built-In Bearings
Premium bearings with integral flanged half-spacers and black ceramic balls.
We all know the steel balls are fast, so there's no telling how fast we'll get moving on some of Seismic's Ceramic Tektons. In addition to being faster in general, ceramic balls dissipate heat more efficiently than their steel counterparts. This means your bearings will stay cooler and so will your wheels. Good news all around! It's also worth noting that ceramic isn't susceptible to rust! (Yes, the cage and integrated spacer can still rust, so don't go puddle hopping with these just yet... Although we've even had very good luck with our steel Tektons in wet conditions!)
If you want some more technical goodness, read Seismic's description below!
Tekton™ 7-Ball XT™ Ceramic Bearings with Patented High-Precision Built-In Spacer System
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 in extra-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 with Tighter Radial Tolerances (3µ – 5µ) that minimize torsional play inside bearing assemblies. Locks in super-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 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. Extends 0.5mm outside to form built-in washer. No bearing spacers, axle washers, or World Record budgets required!
Additional Features: Black outer casings, removable rubber-coated steel seals with printed graphic.
Meets or exceeds all criteria for ABEC-9 rating.
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.
