Introducing the newest bearing innovation from Seismic: The Tekton 7-Ball XT Steel Built-In Longboard Skateboard Bearings!

50% Stronger XT (Extra-Tough) Steel Casings than the previous bearing.

The integrated spacer in the Tekton Bearings is self-aligning, therefore making sure that you get a proper spin without having to worry about how precise your bearing seats or axles are. The Tekton Bearing is designed to correct small (but substantial) flaws in your axles and bearing seats to allow your wheels to spin faster and maintain more of their intended characteristics. The widened lip at the connection point between the bearings is the key to this design. By having a larger and more precise contact patch between the two bearings, you can be sure your wheels are performing to their full potential.

Note: These bearings will not fit on streets skate wheels. For street skate wheels try Tekton Classic or Tekton LITE Built-In bearings.

Seismic's Description

Tekton™ 7-Ball XT™ Steel Bearings with Patented High-Precision Built-In Spacer System
The bearing behind the Official IGSA Downhill Speed World Record – 80.83 mph by Mischo Erban!
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 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. 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 graphics.

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.

The first time I rode these bearings I was hooked, I live in the desert with only one smooth hill. These bearings handle the rough terrain, the extreme heat these last three weeks; 105 F - 45.5 C, and all the sand. Didn't need to clean them for a lot longer then I thought. Try 'em, there worth it.
