Onewheel Ceramic Hybrid Bearing – The 6907 Series (35mm X 55mm) Ceramic Hybrid Wheel/Axle bearings are produced with steel races and ceramic balls and have rubber seals to keep the elements out.

CERAMIC BEARING
BENEFITS:

Reduced
rolling resistance mainly results from the ceramic balls having increased smoothness, dimensional stability, and
increased uniformity of their steel ball
bearing counterparts. These properties
ensure that the applied loads are more evenly distributed
distributed over all of the rolling
elements. Additionally, ceramic materials have a much lower coefficient of friction (~20–30 times less) than
steel ball bearings with standard seals and lubrication. This reduced friction
results in less rolling resistance and
faster rotational speeds.

Ceramic
Bearings are also harder than steel bearings and are therefore more durable.
Studies have shown that ceramic hybrid bearings can last anywhere from 5 to 20 times longer. The smoother surface of the ceramic balls
also significantly reduces the risk of bearing seizure with little to no
lubrication. An additional benefit is their
ability to operate in harsh environments due to corrosion
resistance. Finally, their electrical insulation
properties eliminate the risk of electrical erosion and pitting of the rolling
elements.

Each order includes a set of Bearings (2 Units).
