The fastest speed has to have the ultimate bearings. Si3N4 ceramic skate board bearings are 50% lighter than steel and 40% stronger. So finely balanced, they have an incredible maximum spin rating of 100,000 rpm under load. Each ball is more round than the best steel bearing of any type, grade or benchmark. At 25mph, the calculated energy saving from these alone is 0.8 to 1.0 watts over the standard Precision Steel bearing , A custom thermoplastic retainer physically separates and locates each individual ball within the bearing race for optimum performance and longevity. Further protection is fill with high speed cream. Double light contact seals on polished races provide a final near friction free protective barrier against the elements. The bearing races themselves are a hybrid ceramic specific alloy finely ground and polished to a ABEC9 standard and cryogenically treated at -300 degrees Fahrenheit to refine the molecular structure.


The standard kingsk8 high performance and competition ceramic skate board bearings uses a Grade 5 ball (even use a Grade 3 if highest quality you want, the finest available) and ABEC9 races, while most other ceramics on the market are using Grade 10 or Grade 25 balls with an low pricesion race making them actually less efficient than the standard kingsk8 Precision ceramic skate bearings.


Ceramic skate board bearings have quickly proven themselves far superior to their steel counterparts. Increased demands for more efficient and quicker production have uncovered many weaknesses in the use of steel bearings. Faster production speeds mean more loads and negative forces are being applied to the steel parts. As temperatures and friction increase with the higher production speeds the steel rolling elements and their surrounding rings will show small imperfections that ca n shorten the life span of the bearing. Lubrication for the bearings will also wear out quickly causing the parts to seize possibly causing more damage to the machine than just needing to replace the bearing.


The Kingsk8 high performance and competition ceramic skate board bearings are the absolutely highest grade and tolerance ever available in the skateboard and skate industry.




Kingsk8 ceramic skate board bearings compared with traditional metal bearing, ceramic bearing is featured in following:


1.Could be used at higher temperature. Ceramic maintains mechanical properties at high temperature,ceramic bearing can be used at elevated temperature.

2.Corrosion resistant. ceramic bearing are more suitable for chemical industry application.

3.More suitable for temperature-variation application. Because thermal expansion co-efficiency of ceramic are smaller than metal, so the change of clearance of ceramic bearing is smaller than that of metal bearing.

4.More resistance to seizing due to smaller thermal expansion when skateboarding a long time.

5. ceramic skate board bearings can work under poor lubrication, because ceramics are self-lubrication. ceramic bearing could be used at high-vacuum environment.

6.Could be used as insulation bearing and can prevent Electrical Arcing because ceramics is not electrical conductor.

7.Could be used in magnetic environment because ceramics do not respond to magnetic forces.
