Seimic FullSpin 8mm 7Ball Steel XT Built-In Bearings Silver

Product Description

Seimic FullSpin 8mm 7Ball Steel XT Built-In Bearings Silver. The Fullspin® 7-Ball Steel XT™ Bearings are the pinnacle of modern skate bearing engineering, developed with a team of top American engineers and manufactured in one of the world’s leading bearing factories. Built to fit standard 8mm axles, these bearings combine advanced materials, precise tolerances, and a patented built-in spacer system for unmatched speed, control, and durability. Designed to meet the highest standards of skateboarding performance, they are the go-to choice for riders who demand the absolute best. The 7-ball configuration offers the ideal balance of speed, strength, and impact resistance, making it perfect for high-speed slides, tight turns, and all types of technical riding. Inside, premium Grade G10 steel balls reduce friction for a smoother, more consistent roll, while the exceptionally tight tolerances in the raceways and assembly help minimize play, noise, and wear. Extra-thick steel outer rings with a 60% stiffer profile resist flexing on heavy impacts and retain their speed and shape over time. A premium black oxide coating adds advanced rust protection to further extend bearing life. At the core of the XT is Fullspin’s patented built-in spacer and alignment system—engineered for next-level performance. The built-in half-spacers feature extra-wide flanged ends that provide over twice the contact surface of standard built-in setups. This added surface area dramatically improves bearing alignment, steadiness, and paired performance. Combined with all other features, the system supports incredibly consistent wheel contact and grip, improves slide predictability, and extends the life of both wheels and bearings. To protect against the elements, Fullspin uses labyrinth-style seals that slot into V-shaped grooves to block dust and debris, while next-generation ball retainers act as a second line of defense against grime. A specially formulated high-performance lubricant ensures these bearings operate at their best under the real-world demands of skateboarding—not just in free-spin tests. For riders pushing the limits of street, park, and downhill performance, the Fullspin 7-Ball Steel XT™ Bearings deliver a level of precision, speed, and durability that puts them in a class of their own.
