Quantum Science "Eclipse" Full Ceramic Premium Skateboard Bearing Kit (Top of the Line)

Quantum "Eclipse" Full Ceramic Bearings 

Top of the Line - Ultra Premium Quality

Full Ceramic + Diamond Matrix coating (DMx)

*These are low impact/high speed and designed mainly for street cruising/surf skating and low impact skateboarding. 

*Bearing Press Tool is Required 

Quantum Description:

When fast and smooth are not enough, consider the Eclipse series full ceramic bearing. Extremely low coefficient of friction and low centrifugal forces make this bearing the fastest bearing out there. There is no other skate bearing like it on the planet.

Eclipse series bearings feature high precision ZrO2 ceramic inner/outer rings with a weatherproof Diamond Matrix coating applied, diamond polished raceways and rolling elements, silicon nitride (Si3N4) rolling elements, high strength thermoplastic cage, and our proprietary Graphflo engineered lubrication process.

Each Eclipse Series Bearing Kit Includes:

8 x eclipse series bearings

16 x frictionless shields (8 installed, 8 spares)

8 x speed washers

1 x tube of low-viscosity bearing lubricant (2ml, single use)

1 x sticker

CAUTION – These are full ceramic bearings (ceramic inner ring, ceramic outer ring, ceramic rollers). These bearings MUST be installed using a bearing press or QUANTUM bearing tool (no truck axles). Precision spacers are highly recommended when using full ceramic bearings.

USE CASE: While incredibly fast and smooth, full ceramic bearings are also more brittle compared to chrome steel. These bearings should only be used for very low impact longboard or e-board cruising only with low durometer wheels (88A or below).
