Introducing the newest bearing innovation from Seismic: Tekton 7-Ball XT Ceramic Classic Free Spacer Bearings

Premium bearings with precision-profiled steel 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!

Seismic's Description

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! 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.

Additional Features: Black outer casings, removable rubber-coated steel seals with printed graphic.

Meets or exceeds all criteria for ABEC-9 rating.
