Fullspin™ 7-Ball LITE Classic Bearings

Classic configuration. Best overall balance of speed and resistance to frequent impacts and side loads. Recommended for high-speed turning and sliding (e.g., DH, Freeride, Slalom, Luge, Pump Track) and all style / trick disciplines (e.g., Street, Park, Pool, Ramp, SurfSkate, Flatland and Longboard Freestyle).

Superior concentricity, surface smoothness, strength, and durability. Manufactured to Grade G10 spec for truer, lower-friction ball spin inside bearings; less energy loss; more speed; and longer bearing life.

Compared to balls used in run-of-the-mill skate bearings, G10 specs are 60% – 80% tighter for concentricity (roundness), and 50% – 67% stricter for surface smoothness. (In simpler terms, twice as smooth as the finest cue ball, 10 times as smooth as a mirror finish.)

Manufacturing specifications for raceways and assembly are highly technical considerations, but absolutely mission-critical to overall bearing performance. Unlike other skate brands, Seismic fully committed to mastering the science and optimizing every last parameter.

See footnote below for the finer points.¹ The important takeaway is: Specs as tight and accurate as Fullspin’s are only possible at the very biggest, best-equipped, and most skillful factories in the world. The average small skate bearing producer can’t even come close.

The bottom line for rolling performance: Fullspin’s world-class factory tolerances result in significantly less internal play, friction, wear, and noise; and noticeably superior speed, handling, and durability!

¹ Radial clearance (gap between balls and raceway surfaces) held within a super tight and narrow range, with remarkably little deviation from the exact middle. Synergizes with extra-strict raceway curvature radius for outstandingly balanced load distribution across balls – a key determinant of overall bearing efficiency and toughness. Raceway surface finish up to 40% smoother than well-known brands. Superior tolerances for outer and inner ring concentricity (roundness), too.

Inner and outer rings precision-machined from superior steel with advanced heat treatment that fully optimizes metal’s crystalline microstructure. Raceways hold strictest curvature and finest surface finish – and bearings stay tight and fast – for far longer.

Outer rings are thicker and 60% stiffer than those seen on most other skate bearings (made with inferior steel). So they resist flexing, spin truer and faster, and keep seals from popping off on extreme impacts. Coated with a strong rust-preventative agent, but more economically finished without the black oxide anti-corrosion surface treatment seen in premium Steel and Ceramic XT models.

Radius reduced to bare minimum on all edges of both outer and inner rings – for fuller contact and more stable alignment inside bearing pockets of finer wheels; on axles of finer trucks; and at Built-In spacer interfaces. A Fullspin first!

Second only to Fullspin’s own profiled free spacer design (seen in Ceramic XT Classic models), this is the most advanced Classic bearing alignment tech available in the skate world, and it unlocks outstanding paired performance.

Fullspin’s standard spacers are anything but ordinary – made with superior metal, smarter and stricter dimensional specs, and thicker walls that square up against matching extra-wide inner ring surfaces with superior precision and stability.

System levels and steadies all working components of seated bearings much more precisely and stably than Classic designs from other brands – which typically use spacers rough-cut from thin-walled, easily-bent iron or aluminum, with oversized bores that rock on axles.

Synergizes with all advanced features in individual bearings to maintain highly consistent wheel contact and grip; support more predictable slide performance; and extend both wheel and bearing life

Precision-machined from premium bearing steel with advanced heat-treatment for unmatched strength and toughness.

Spacer width set to extra-strict 0.400-inch tolerance, to support highly accurate positioning of paired bearings inside finer wheels with well-engineered hubs.

Radius reduced to bare minimum on all edges (inner rings of bearings and ends of spacers), for fuller contact and more stable alignment at spacer interfaces.

All bore specs (spacer as well as inner ring) dialed to maintain exceptional straightness on finer axles.

Premium Ceramic models include profiled spacers with extra-wide contacts that boost alignment precision even further. (Also available separately.)

Packed with premium “high-RPM” light grease from Kyodo Japan. Formulated for peak performance under real-world skating stresses, not max free-spin time. Just press into your wheels and go!¹

Note: Free-spinning bearings or wheels by hand, under zero load, is not a meaningful measure of real-world performance (though none of us can resist free-spinning fresh new wheels and bearings). Fullspin’s advanced lubricant is designed to perform best when warmed up under the load of a human skater who’s rolling, turning, and sliding on real asphalt or concrete.²

¹ Do not clean – or add extra lubricant to – brand new Fullspin bearings. Wipe grime off outer seals whenever excess builds up. Clean and re-lube bearings only as needed, depending on how often and where you skate – more frequently if you ride through water, mud, dirt, or sand. Do not remove outer seals or disassemble in any way; just soak in isopropyl alcohol (70% solution or greater), rinse, and let dry. Avoid excessive cleaning, which increases risk of accidental damage to small internal components, as well as citrus-based cleaning solutions, which cause corrosion.
² Bearings may gain extended free-spin time if they’re under-lubricated, or lubricated with very thin oil, or assembled too loosely. But under real-world skating stresses, they won’t perform as well or hold up as long as high-quality bearings with tight assembly tolerances and appropriate lubricant – even though the latter may have a shorter free-spin. Most skating speed records have been set on bearings with modest free-spin. What matters is how bearings handle under the load of a human rider’s bodyweight – rolling, turning, and sliding on real asphalt or concrete.

Removable rubber-coated “no contact” steel seals with printed graphic. Edges of seals slot inside V-shaped grooves machined into both outer and inner rings. This “Labyrinth” interface maximizes resistance to dust and debris – which can only penetrate the bearing by navigating a twisting, maze-like path around seal edges.

Note: Seals protect bearings from environmental contaminants, which significantly accelerate wear. Properly-made “no contact” seals do not add friction. Brands that promote completely unsealed bearings just want you to wear yours out faster so they can sell you another set (that will also wear out prematurely).

Fullspin’s custom ball retainers keep bearings cleaner for longer, without the addition of a second seal. They feature an expanded outer diameter that slots into a groove in the outer ring just like a second seal – to form a unique integral barrier against dirt and grime.

Molded from an engineering-grade fiber-reinforced composite specifically formulated by the German producer for high stiffness and dimensional stability in bearing retainers and similar components.

We don’t bother with the ABEC rating system, which measures only the most superficial dimensional tolerances of the outer and inner rings – all of negligible relevance to real-world skating performance.

Other bearing brands frequently inflate or fabricate ABEC ratings to mislead the buying public. But even when accurately measured and reported, low-versus-high ABEC ratings have no direct correspondence with poor-versus excellent skating performance in the real world.

No wasteful, oversized metal tins or plastic cases – just a minimal recyclable cardboard box. Bearings and spacers wrapped inside VCI (“Volatile Corrosion Inhibitor”) paper – another Fullspin first! Adds superior protection against corrosion during transit and long-term storage of unopened packages.

Just superior performance through genuinely advanced, no-BS engineering; highest-quality materials and components; and highest-precision manufacturing.

100% FREE OF:
– Random bearing tech inappropriately adapted from other industries solely for the sake of novelty.
– High-sounding raceway coatings that interfere with optimal finishing and cause abrasive damage to ball surfaces.
– Flashy lubricant additives that accelerate wear not speed.
– Bombastic references to features and processes like the following (all totally ordinary and unexceptional at any decent, self-respecting skate bearing factory): deep-groove raceways with micro-channels, fine-polishing, fiber-reinforced nylon retainers, hand-inspection, and ultrasonic solvent washing.
