Seismic Tekton Ceramic Bearings
The bearing behind the Official Downhill Speed World Record – 80.83 mph by Mischo Erban!
Now with tighter assembly tolerances!
Already in a class by itself, black ceramic balls send the self-aligning Tekton design to a whole new realm of fast.
Compared to even the finest steel bearing balls, ceramic balls have several remarkable advantages that justify their higher cost. They’re significantly lighter and lower in friction, so they accelerate faster and roll further at a higher speed, even with little or no lubricant. They’re so hard and strong that they crush dirt, debris, and even rust, which keeps the steel raceways clean and polished. They dissipate heat better, so bearings (and wheels) run cooler. They’re also rustproof, so they last longer even when ridden in wet conditions.
Seismic® Tekton bearings feature wide, flat contact surfaces at the ends of integrated, custom-machined half-spacers. The broad flanges square up, co-align and self-stabilize inside your wheels – correcting for flaws in bearing seat levelness, bearing seat spacing, axle diameter and axle straightness.
The Tektons literally block themselves from sitting or rocking out of alignment, so they stay straighter than any other bearing system ever. Your wheels roll faster with better control, while the bearings last longer and stay quieter.
Other features include: top-quality black trisilicon tetranitride (Si3N4) balls, nylon retainers, black outer casing, removable rubber-coated steel seals with printed graphic, and high-end Japanese Kyodo grease. Construction meets or exceeds requirements for ABEC-7 rating.
The inner race is stepped underneath the seal to resist contamination, and it’s stepped between the bearing and the flange to save weight. On the side opposite the flange, the inner race extends 0.5mm to form a thin integrated washer. No bearing spacers or axle washers.
