The bearing behind the Official IGSA Downhill Speed World Record! Tektons should not be confused with bearings that have their inner races stretched on one side to form a simple half-spacer. Sometimes called “industrial” bearings, these have been used in pre-assembled skateboards since the 1970s, and more recently for racing, but they’re still vulnerable to misalignment. The diameter of the Tektons’ flanged contact surfaces is up to 35% larger compared to bearings coupled with floating spacers, and up to 23% larger compared to bearings with stretched inner races. This translates to exponentially better correction for flaws in bearing seat levelness, bearing seat spacing, axle diameter and axle straightness.Tekton bearings, rated at ABEC-7, are precisely dimensioned to provide superior alignment safeguards in all modern high-performance skateboard wheels. Features include steel balls, nylon retainers, black outer casing, removable rubber-coated steel seals with printed graphic, and a proprietary lubricant combining both oil and grease.
The inner race is stepped underneath the seal to resist contamination, and it’s stepped between the bearing and the flange to save weight. (A set of Tektons weighs the same as a set of conventional bearings with simple floating spacers.) On the side opposite the flange, the inner race extends 0.5mm to form a thin integrated washer.
