Tekton Precision-Profiled XT Steel Spacers

Built-In: Integral half-spacers square up and self-stabilize inside wheels. Extra-wide contacts on XT models (U.S. Pat. #9,126,101) align bearings better than any other system – even correcting for off-spec axles and misaligned bearing seats. Inner race extends 0.5mm outside, eliminating need for axle washers.

Classic: Precisely-sized free spacers square up against bearings and stabilize them inside wheels. Premium Ceramic models include Profiled Steel Spacers with extra-wide contacts – a Tekton innovation that brings a revolutionary new level of durable alignment to free-spaced bearings. (Also available separately.)

Tekton’s superior spacing tech synergizes with Tighter Radial Tolerances that minimize torsional play inside bearing assemblies. Locks in highly-precise alignment, protects against friction and wear, minimizes noise.

Standard: Superior steel and thicker outer casings boost strength 30%! Standard heat treatment applied.

XT (Extra-Tough): Superior steel and thicker outer casings PLUS ultra-premium heat treatment that fully optimizes steel’s microstructure and catapults strength 50% beyond ordinary bearings!

Tekton’s much stiffer, tougher casings resist flexing, spin truer and faster, and keep seals from popping off on extreme impacts. Ball raceways hold smooth polish, and bearings stay tight and fast, for far longer!

Meets or exceeds all criteria for ABEC-9 rating.

7-Ball: Best overall balance of speed and resistance to frequent high impacts and side loads.

6-Ball: Six larger, stronger balls. Less total friction, better acceleration and speed on straightaways!

Premium Steel: Highest grade available. Superior concentricity, surface smoothness, strength, and durability.

Premium Black Ceramic (Si3N4): Lighter, smoother, harder, heat-resistant, rustproof. Reduces friction, increases acceleration and speed, scours and cleans raceways.

Packed with premium “high-RPM” lubricant from Kyodo Japan, one of the world’s most renowned lubricant suppliers. Formulated for peak performance under real-world skating stresses, NOT max free-spin time.

Advanced dust-resistant ball retainer keeps bearings cleaner for longer, like a second seal with no added friction. Formed from Dupont engineering-grade Nylon for superior durability.

Inner race contoured under outside seal to resist contamination. Extends 0.5mm on seal-side of built-in models, eliminating need for axle washers.

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 longer life through real science and no-BS engineering!
