# Seismic - Tekton 7-Ball XT Ceramic Classic

**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! 5_0%-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._
