Full disclosure: what follows is Seismic‘s own text for the Tekton XT Classic bearings. We’ve just copy and pasted it because… well… there’s a lot of text here. All we’ll add is that, yes, these bearings are bloody good.
Next-level skate bearing tech – more speed, better handling, longer life!
- Versatile Free-Spaced Design
- 50% Stronger XT (Extra-Tough) Steel Casings
- Tighter Assembly Tolerances
- Dust-Resistant Ball Retainers
- Premium Lube
– More speed & acceleration
– Consistent wheel contact & grip
– Predictable slide release & hookup
– Extended wheel & bearing life
Versatile Free-Spacer System: Precisely-sized spacers square up against bearings and stabilize them inside wheels. Combines with Tighter Radial Tolerances (3µ – 5µ) that minimize torsional play inside bearing assemblies. Locks in highly-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 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.
